I AM YOU

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights that help women understand their unique heart health, manage stress, and take charge of their well-being. Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez explores a frustrating experience many women know all too well: being told their medical tests are “normal” even when they know something isn't right. You'll meet a 44-year-old woman who felt that something was off despite normal blood work, an EKG, and a routine checkup. As Dr. Alvarez explored her sleep, menstrual cycle, energy levels, and nighttime heart palpitations, a more complete picture began to emerge.

Dr. Alvarez explains the critical difference between the absence of diagnosed disease and optimal health. Standard medical tests often identify established disease but may miss early physiological changes, subtle cardiovascular dysfunction, and hormonal transitions that affect how women feel long before conventional test results become abnormal.

She also discusses ischemia with non-obstructive coronary arteries (INOCA), a condition in which women can experience genuine cardiovascular symptoms despite having no significant blockages in their major coronary arteries. Drawing on findings from the Women's Ischemia Syndrome Evaluation (WISE) study, she highlights why women's cardiovascular symptoms deserve careful investigation, even when standard testing appears reassuring.

With clarity and compassion, she covers:

• Why a normal medical test does not necessarily mean your body is functioning optimally
• The important difference between detecting established disease and identifying early physiological dysfunction
• How INOCA and small blood vessel dysfunction can cause cardiovascular symptoms even when major coronary arteries appear clear
• What the WISE study reveals about cardiovascular disease in women without obstructive coronary artery disease
• How fluctuating estrogen levels during perimenopause can affect blood vessel function and cardiovascular health
• Why being within a laboratory reference range does not automatically mean a result is optimal for your individual health
• Why persistent symptoms should not be dismissed simply because initial testing fails to identify a problem
• How tracking symptoms, energy levels, sleep, menstrual cycles, and other patterns can help uncover important clues
• Why asking whether your health is optimal—not simply whether something is wrong—can change the conversation with your provider
• Five practical steps to advocate for yourself when your body tells you something isn't right

This episode is a powerful reminder that “normal” and “optimal” are not the same thing. A normal test result may be reassuring, but it does not always tell the whole story. Dr. Alvarez encourages women to recognize early warning signs, pay attention to changes in their bodies, and work with healthcare professionals who look beyond laboratory results to understand the complete picture.

Becoming the CEO of your own health means trusting your experience, asking better questions, understanding how hormones and cardiovascular health are connected, and taking proactive steps toward prevention—before a diagnosis appears on paper.

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights that help women understand their unique heart health, manage stress, and take charge of their well-being. Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez challenges a dangerous misconception: that a normal treadmill stress test means your heart is healthy. You’ll meet a 52-year-old woman who recently went through menopause and began experiencing unexplained fatigue, shortness of breath, chest tightness, and occasional jaw discomfort. Despite these symptoms, her treadmill stress test and blood work came back normal. She was told it was probably stress or anxiety, but her symptoms continued for months.

Dr. Alvarez explains why traditional treadmill stress tests can miss cardiovascular disease in women. While these tests primarily look for signs of significant blockages in the large coronary arteries, many women experience problems in the heart’s smaller blood vessels—a condition known as coronary microvascular dysfunction. She explores how differences in women’s cardiovascular physiology, hormonal changes during menopause, and limitations in standard testing can lead to missed diagnoses and delayed treatment.

With clarity and compassion, she covers:

• What a treadmill stress test actually measures—and why a normal result doesn’t necessarily mean your heart is healthy
• Why traditional exercise stress tests can be less accurate in women than in men
• How coronary microvascular dysfunction affects the heart’s smallest blood vessels, even when major arteries appear clear
• What INOCA (ischemia with non-obstructive coronary arteries) means and why it matters for women’s cardiovascular health
• Why symptoms such as fatigue, breathlessness, chest tightness, and jaw discomfort should not automatically be dismissed as anxiety
• How declining estrogen during menopause affects blood vessel function and increases the risk of microvascular dysfunction
• Why microvascular disease is not harmless and can increase the risk of serious cardiovascular complications
• How advanced diagnostic tools—including stress echocardiography, cardiac MRI, PET imaging, and coronary CT angiography—can reveal problems that standard treadmill tests may miss
• Why understanding coronary flow reserve can help identify problems in the heart’s small blood vessels
• How to ask your provider whether persistent symptoms could be caused by microvascular disease or INOCA
• Why tracking your symptoms, pregnancy history, blood pressure, cholesterol, blood sugar, family history, and menopause timeline can improve your cardiovascular evaluation
• Five practical steps to advocate for yourself when your symptoms persist despite normal test results

This episode is a reminder that a normal stress test does not always mean a healthy heart. When your symptoms continue but your test results suggest everything is fine, you deserve answers—not dismissal. Understanding the limitations of traditional testing, recognizing the importance of hormonal changes, and knowing when to seek specialized care can make a meaningful difference in protecting your cardiovascular health.

Becoming the CEO of your own health means listening to your body, asking informed questions, understanding your risk factors, and advocating for the right evaluation. Your symptoms matter, and finding answers starts with knowing where to look.

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights that help women understand their unique heart health, manage stress, and take charge of their well-being. Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez explores why women can visit multiple specialists, undergo numerous tests, and still walk away without answers. You’ll meet a 47-year-old woman struggling with unexplained fatigue, a racing heart, joint pain, mood changes, and brain fog. Despite seeing different specialists, she repeatedly hears the same message: everything looks fine. But if every doctor says she’s healthy, why does she still feel that something is wrong?

Dr. Alvarez explains how modern medicine’s focus on individual organs and specialties can overlook the bigger picture of women’s health. Symptoms that appear unrelated may actually be connected through hormonal changes, particularly during perimenopause and menopause. As estrogen levels fluctuate, they can affect the heart, blood vessels, nervous system, sleep, joints, and mood. Understanding these connections is essential to recognizing patterns that individual tests and specialist evaluations may miss.

With clarity and compassion, she covers:

• Why seeing multiple specialists doesn’t always lead to a complete understanding of your health
• How seemingly unrelated symptoms can be connected through hormonal changes
• Why fatigue, heart palpitations, joint pain, brain fog, and mood changes may be part of a larger pattern
• How fluctuating estrogen levels affect the cardiovascular system, nervous system, and overall well-being
• Why perimenopause can cause symptoms that are easily overlooked or dismissed
• Why normal test results from individual specialists don’t necessarily mean everything is fine
• How tracking symptoms over time can reveal patterns that laboratory tests alone may miss
• Why understanding the relationship between hormones and heart health is essential for prevention
• How to organize your symptoms and communicate the complete picture to your healthcare provider
• Why asking whether perimenopause could explain multiple symptoms is an important step
• Five practical steps to help connect the dots and advocate for a more comprehensive evaluation

This episode is a reminder that your body doesn’t operate in separate departments, even when healthcare does. When multiple specialists tell you everything is fine but you continue to experience symptoms, the answer may lie in understanding how those symptoms connect. Becoming the CEO of your own health means listening to your body, recognizing patterns, asking the right questions, and finding healthcare professionals who look at the whole picture—not just one piece of the puzzle. You deserve answers before overlooked symptoms become a preventable diagnosis.

Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez tackles one of the most common and overlooked threats to women’s cardiovascular health: high blood pressure. You’ll meet a 49-year-old woman whose blood pressure began rising alongside headaches, disrupted sleep, and hot flashes. Despite consistently elevated readings, she was told it was probably stress, white coat syndrome, or simply perimenopause.

Dr. Alvarez explains why even slightly elevated blood pressure deserves attention, particularly during perimenopause and menopause. As estrogen levels decline, blood vessels become less flexible, increasing the risk of hypertension, heart disease, and stroke. She separates popular internet remedies from scientifically supported interventions, revealing what actually works to lower blood pressure—and why the most effective solutions often aren’t found in a supplement bottle.

With clarity and compassion, she covers:

• Why blood pressure often rises during perimenopause and menopause
• How declining estrogen affects blood vessel flexibility and cardiovascular risk
• Why even mildly elevated blood pressure should never be ignored
• How the DASH diet can significantly reduce blood pressure
• Why reducing sodium and increasing potassium from food can make a measurable difference
• How regular aerobic exercise, including walking, cycling, and swimming, helps lower blood pressure
• Why isometric exercises, such as wall sits, may be particularly effective
• How weight management, limiting alcohol, and improving sleep contribute to healthier blood pressure
• Why popular remedies like magnesium, apple cider vinegar, and supplements cannot replace proven treatments
• Why white coat hypertension still deserves monitoring and follow-up
• How to measure blood pressure correctly at home and track trends over time
• Why combining several lifestyle changes can produce meaningful improvements
• Five practical steps to take control of your blood pressure and advocate for better cardiovascular care

This episode is a reminder that high blood pressure is not just a number—it’s a signal your body is sending. You don’t have to wait for symptoms or a crisis to take action. Small, consistent changes in nutrition, movement, and daily habits can make a significant difference in protecting your heart. Becoming the CEO of your own health means knowing your numbers, understanding how hormonal changes affect your cardiovascular health, asking the right questions, and taking action before preventable problems become serious.

Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez explores why so many women experience confusing and seemingly unrelated symptoms during midlife—and why these changes are anything but random. You’ll meet a 43-year-old woman struggling to understand why her menstrual cycles were changing, her heart was racing unexpectedly, her sleep was disrupted, and her body composition was shifting despite maintaining the same habits. Her frustration captures what countless women experience during perimenopause: feeling like their bodies are changing without anyone explaining why.

Dr. Alvarez explains how fluctuating estrogen and declining progesterone can affect multiple systems throughout the body, creating symptoms that may seem disconnected but often share a common hormonal cause. From night sweats and disrupted sleep to heart palpitations and metabolic changes, she reveals how the hormonal transitions of perimenopause influence not only reproductive health but also the brain, nervous system, metabolism, and cardiovascular system.

With clarity and compassion, she covers:

• Why midlife symptoms that seem random may actually be connected to hormonal fluctuations
• How estrogen and progesterone change during perimenopause—and why these shifts can feel unpredictable
• Why declining progesterone and fluctuating estrogen can affect sleep, body temperature, and overall well-being
• How hormonal changes influence the autonomic nervous system and contribute to heart palpitations
• Why estrogen plays an important role in blood vessel function and cardiovascular protection
• How perimenopause affects much more than menstrual cycles and hot flashes
• Three common myths about midlife hormonal changes—and the science behind what is really happening
• Why understanding your body’s changing physiology can replace confusion with confidence
• How tracking menstrual cycles, sleep patterns, and symptoms can help identify hormonal changes
• Why discussing perimenopause openly with your healthcare provider is essential
• How sleep, strength training, adequate protein intake, and stress management support heart health during midlife
• Why understanding your options, including hormone therapy, requires guidance from a provider familiar with women’s cardiovascular health
• Five practical steps to better understand your body, manage symptoms, and protect your long-term health

This episode is a reminder that your body is not betraying you—it is changing according to a biological rhythm that deserves to be understood. Perimenopause is not simply something women must endure without answers. Understanding how hormonal changes affect your heart and the rest of your body is an important step toward prevention, informed decisions, and long-term well-being. Becoming the CEO of your own health means recognizing these changes, asking informed questions, and taking an active role in protecting your heart through every stage of life.

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights that help women understand their unique heart health, manage stress, and take charge of their well-being. Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez challenges a dangerous assumption many women hear after cardiac testing: “Your arteries are clean, so it’s not your heart.” You’ll meet a 51-year-old woman experiencing shortness of breath, chest pressure, jaw tightness, and discomfort between her shoulder blades. Her stress test showed ischemia, yet an angiogram found no significant blockages. She was reassured that her arteries were clean and told her symptoms were probably stress or anxiety.

But her symptoms were real—and so was the ischemia.

Dr. Alvarez explains why a normal angiogram does not necessarily mean a normal heart. An angiogram can identify obstructive disease in the large coronary arteries, but it may not identify problems involving the heart’s smaller blood vessels. In women, conditions such as ischemia with non-obstructive coronary arteries (INOCA) and coronary microvascular dysfunction can cause real symptoms and reduced blood flow even when the major arteries appear open.

With clarity and compassion, she covers:

• Why “clean arteries” do not necessarily mean there is nothing wrong with your heart
• How women can experience ischemia without a major coronary blockage
• What INOCA—ischemia with non-obstructive coronary arteries—means
• How coronary microvascular dysfunction affects the heart’s small blood vessels
• Why women’s heart disease can look different from the traditional blockage-based model of cardiovascular disease
• Why chest tightness, shortness of breath, jaw pain, arm discomfort, and pain between the shoulder blades should not automatically be dismissed as anxiety or stress
• Why microvascular dysfunction is not benign and can carry increased cardiovascular risk
• How declining estrogen during perimenopause and menopause can affect blood vessel function and cardiovascular health
• Why “no stent needed” does not mean “no problem”
• How to track and clearly describe your symptoms to your healthcare provider
• Why women with persistent symptoms should ask whether microvascular disease or INOCA could be involved
• Why controlling blood pressure, cholesterol, blood sugar, exercise, sleep, smoking, and other cardiovascular risk factors remains essential
• Five practical steps women can take to advocate for a more complete evaluation when symptoms persist

This episode is a reminder that a clean angiogram should not always be the end of the conversation. Women can have real ischemia and cardiovascular disease even without a significant blockage in the major coronary arteries. Your symptoms are data, and persistent symptoms deserve to be taken seriously.

Becoming the CEO of your own health means listening to your body, understanding what your tests actually evaluated, asking more precise questions, and continuing to seek answers when your symptoms and your test results do not tell the same story. You do not have to wait for a major blockage to deserve a comprehensive heart evaluation.

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode combines real stories with medical insight to help women better understand their heart health, recognize when something may be wrong, and become stronger advocates for their own care. Dr. Alvarez’s mission is to empower every woman to become the CEO of their own health—with knowledge, confidence, and a voice in their healthcare decisions.

In this episode, Dr. Alvarez tackles a problem far too many women experience: medical dismissal. You’ll hear the story of a 55-year-old woman who lived with chest pressure and shortness of breath for two years, only to be told that her symptoms were likely anxiety. Eventually, she began questioning herself and stopped bringing up what she was experiencing.

Dr. Alvarez explains why women’s cardiovascular symptoms can be overlooked or misinterpreted, particularly when they don’t match the traditional “textbook” presentation of heart disease. She explores how symptoms such as fatigue, shortness of breath, nausea, and back or jaw discomfort may be dismissed as stress or anxiety, and why women-specific factors—including microvascular disease and hormonal changes—need to be part of the conversation.

In this episode, she covers:

• Why women’s heart symptoms can be dismissed or misdiagnosed
• How traditional cardiac symptom patterns have historically been based largely on men
• Why fatigue, breathlessness, nausea, and back or jaw discomfort deserve attention
• How anxiety can become a label before physical symptoms have been fully evaluated
• Why women may experience heart disease without the dramatic “textbook” symptoms
• The role of small blood vessels and microvascular disease in women’s heart health
• Why hormonal changes during menopause matter when evaluating cardiovascular risk
• How using specific language to describe symptoms can help your provider understand what you are experiencing
• Why asking your provider to document concerns and conclusions in your medical record can change the conversation
• How bringing a trusted advocate to an appointment can help you ask questions and process information
• When to ask about additional or women-specific cardiac evaluations
• Why getting another opinion when symptoms persist is part of advocating for yourself

This episode is a reminder that persistent symptoms are information—not an inconvenience. If something still feels wrong after you have been evaluated, you can continue asking questions, request clarification about what has and has not been ruled out, and seek another opinion. Becoming the CEO of your own health means listening to your body, communicating clearly, and taking an active role in making sure your concerns are fully evaluated.

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode brings together real stories and medical insights to help women better understand their heart health, recognize important symptoms, and take a more active role in their well-being. Dr. Alvarez’s mission is to empower every woman to become the CEO of their own health—equipped with knowledge, confidence, and the ability to advocate for themselves.

In this episode, Dr. Alvarez examines a troubling scenario: a woman suffers a stroke, yet the scans, blood work, and other testing fail to reveal what caused it.

Roughly one in three ischemic strokes is considered cryptogenic, meaning the cause remains undetermined. But “no cause found” does not always mean there is no underlying cause. Sometimes, the missing piece may be an intermittent heart rhythm problem—particularly atrial fibrillation (AFib) that appears briefly and disappears before routine testing can detect it.

Dr. Alvarez explains how AFib may last only seconds or minutes and can sometimes cause subtle symptoms such as a fluttering or racing heart, fatigue, dizziness, or shortness of breath. For women going through perimenopause or menopause, these symptoms may be attributed to stress, anxiety, or hormonal changes. While hormones can certainly contribute to palpitations, they should not automatically be assumed to be the only explanation.

Throughout the episode, Dr. Alvarez discusses:

• What doctors mean when they classify a stroke as “cryptogenic”
• Why “no cause found” may mean the cause simply has not been identified yet
• The connection between atrial fibrillation and an increased risk of stroke
• Why brief or silent episodes of AFib can be difficult to capture
• How a normal EKG can miss an intermittent heart rhythm abnormality
• Why longer-term rhythm monitoring may uncover what a short test cannot
• How perimenopause, menopause, and changing estrogen levels can affect heart rhythm
• Why palpitations should not automatically be dismissed as anxiety or hormones
• How AFib symptoms in women may include fatigue, dizziness, breathlessness, or less obvious sensations
• Why tracking when symptoms occur, how long they last, and what accompanies them can help your provider see important patterns
• When it may be appropriate to ask about longer-term heart rhythm monitoring
• Why women who have experienced a stroke with no identified cause should ask whether hidden AFib was adequately investigated
• Practical steps women can take to advocate for a more complete evaluation when something does not feel right

The central message of this episode is that symptoms are information. A flutter that lasts only a minute, a racing heart in the middle of the night, or an unexplained episode of dizziness may be easy to overlook—especially when an initial EKG or other testing comes back normal. But intermittent rhythm problems can be difficult to detect precisely because they are not always happening when the test is performed.

Becoming the CEO of your own health means paying attention to patterns, understanding what your testing actually evaluated, and asking additional questions when symptoms continue. When it comes to preventing stroke, finding a hidden cause before it leads to a serious event can make all the difference.

Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez challenges one of the most frustrating words a woman can hear when she knows something is wrong: “normal.” You’ll meet a 48-year-old woman who spent a year dealing with exhaustion, shortness of breath, and a pounding heart—only to be told again and again that her tests were normal.

Dr. Alvarez explains why a normal test result does not necessarily mean that nothing is wrong. Standard testing may be effective at identifying large, obvious problems, while missing conditions that can present differently in women—including disease involving the small blood vessels, early cardiovascular changes, and issues influenced by hormonal transitions.

With clarity and compassion, she covers:

• What doctors may actually mean when they say a test is “normal”
• Why normal test results don’t necessarily rule out an underlying problem
• How cardiovascular disease can present differently in women, including microvascular disease
• Why hormonal changes and declining estrogen matter when evaluating a woman’s cardiovascular health
• Why persistent symptoms deserve further investigation—even when the initial workup is normal
• How to ask your provider exactly what a test ruled out—and what it did not
• Why asking about women-specific evaluations and additional testing can matter
• How to make sure ongoing symptoms are documented in your medical record
• Why seeking a second opinion is not disloyalty—it’s diligence
• Five practical steps to advocate for yourself when your body tells you something is wrong

This episode is a reminder that “normal” should not always be the end of the conversation. When a test says everything looks normal but your symptoms continue, you are allowed to keep asking questions, seek another opinion, and advocate for a deeper evaluation. Becoming the CEO of your own health means understanding what your test results actually tell you, listening to your body, and continuing to search for answers when something doesn’t feel right.

I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights that help women understand their unique heart health, manage stress, and take charge of their well-being. Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of their own health—with knowledge, confidence, and community.

In this episode, Dr. Alvarez explores an often-overlooked early warning sign of cardiovascular disease: endothelial dysfunction—the loss of the artery lining’s ability to properly relax and regulate blood flow.

Through the story of a woman experiencing persistent cold hands, chest tightness when climbing stairs, fatigue, mildly elevated cholesterol, and the changes of perimenopause, Dr. Alvarez explains why symptoms that are often dismissed as stress, anxiety, aging, or hormones may deserve a closer cardiovascular look.

Dr. Alvarez breaks down how the endothelium—the thin layer of cells lining every artery in the body—uses nitric oxide to signal blood vessels to relax and allow healthy blood flow. She explains how elevated cholesterol can damage this delicate system long before a major blockage appears, and how declining estrogen during the menopause transition can further reduce the body’s ability to produce nitric oxide.

Most importantly, this is a story of hope: endothelial dysfunction is one of the earliest and most reversible stages of cardiovascular disease, and early intervention can help restore healthy vascular function.

With clarity and compassion, she covers:

• What the endothelium is and why this tiny layer of cells plays such a major role in cardiovascular health
• How nitric oxide signals arteries to relax and support healthy blood flow
• Why cholesterol matters beyond simply being a number on a lab report
• How endothelial dysfunction can begin before plaque or blockages are visible on conventional testing
• Why cold hands, chest tightness with exertion, and unexplained fatigue should not automatically be dismissed as stress or anxiety
• How falling estrogen during perimenopause and menopause affects nitric oxide and vascular function
• Why menopause and cardiovascular health should be part of the same conversation
• How lowering cardiovascular risk can allow endothelial function to improve—even before the artery itself looks structurally perfect
• Why women should know their LDL and understand it in the context of their overall cardiovascular and hormonal risk
• Practical ways to protect the endothelium through movement, nutrition, sleep, avoiding smoking, and appropriate medical care
• When new or worsening chest tightness—especially with exertion—needs prompt medical evaluation

This episode is a reminder that prevention begins long before a heart attack or a major blockage. Your symptoms are data. Your cholesterol, hormones, and symptoms should be evaluated as part of one cardiovascular story—not treated as unrelated issues.

Do not wait for an early, reversible warning sign to become an emergency. Listen to your body, ask better questions, and advocate for comprehensive care as the CEO of your own health.
