Join CardioNerds EP Council Chair Dr. Naima Maqsood and Episode Lead Dr. Jeanne De Lavallaz as they discuss the results of the VANISH2 Trial with expert faculty Dr. Jeff Healey and Dr. Roderick Tung. Audio editing by CardioNerds academy intern, Grace Qiu.

The VANISH2 trial enrolled 416 patients with ischemic cardiomyopathy, an ICD in place, and recurrent episodes of sustained monomorphic ventricular tachycardia (VT) to receive either first-line VT catheter ablation or antiarrhythmic drug therapy with the primary composite outcome of death from any cause, appropriate ICD shock, ventricular tachycardia storm (meaning at least 3 ventricular tachycardia events within 24hrs) or treated ventricular tachycardia below the detection limit of the ICD. The study population had a mean age of 68 years, with 94% being men and predominantly of white ethnicity. On average, 14 years had elapsed since their last myocardial infarction, with approximately 60% having undergone percutaneous coronary intervention at the time. The mean ejection fraction was 34%.

This episode was planned in collaboration with Heart Rhythm TV with mentorship from Dr. Daniel Alyesh and Dr. Mehak Dhande.

Join CardioNerds EP Council Chair Dr. Naima Maqsood and Episode Lead Dr. Jeanne De Lavallaz as they discuss the results of the ARREST-AF Trial with expert faculty Dr. Prashanthan Sanders and Dr. Mehak Dhande. Audio editing by CardioNerds intern Bhavya Shah.

The ARREST-AF trial enrolled 122 patients with a BMI of 27 kg/m2 or greater and at least one cardiovascular risk factor with either paroxysmal or persistent AF and were scheduled to undergo de novo AF ablation. They were randomized to an intensive risk factor management (RFM) program versus usual care. The RFM program addressed obesity, sleep apnea, HTN, HLD, tobacco, and alcohol abuse, whereas the usual care arm had a discussion of risk factors but without an extensive risk factor modification or follow-up program. The study population had a mean age of 60 years, a mean BMI of 33 kg/m2, and 56-60% of patients with persistent AF. A third of the study population was female. The trial showed a significant improvement in the primary endpoint of the percentage of patients free from atrial fibrillation after ablation in those receiving the intensive lifestyle RFM program. At the end of the 12.3-month follow-up period, 66% percent of patients in the RFM group were free from AF compared to 42% in the usual care group (HR 0.53, p = 0.03). The RFM group also showed significant improvement in AF symptom severity, decline in body weight, systolic blood pressure, glycemic control, and exercise capacity. On average, patients in the RFM arm lost 9 kg of weight compared to 1 kg in the control group. Similarly, systolic blood pressure decreased by 13.1 mmHg in the RFM group but increased by four mmHg in the control group.

Join CardioNerds Heart Failure Section Chair Dr. Jenna Skowronski, episode lead Dr. Merna Hussein, and expert faculty Dr. Milton Packer as they discuss the SUMMIT trial.

The SUMMIT trial randomized 731 patients with HFpEF with LVEF ≥ 50% and obesity with BMI ≥ 30 kg/m2 to receive tirzepatide or placebo for at least 52 weeks. The two co-primary endpoints were a composite of time to cardiovascular death or a worsening heart failure event and quality of life measured by the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS). Treatment with tirzepatide led to a lower risk of the composite of cardiovascular death or worsening heart failure as well as improved quality of life.

This episode was planned in collaboration with the American College of Cardiology Section of the Prevention of Cardiovascular Disease with mentorship from Section Chair Dr. Eugenia Gianos.

Join CardioNerds Heart Failure Section Chair Dr. Jenna Skowronski, episode lead Dr. Apoorva Gangavelli, and expert faculty Dr. Ronald Witteles as they discuss the Nex-Z trial.

This was a phase 1, open-label trial investigating nex-z, a CRISPR-Cas9-based treatment, in 36 patients with transthyretin amyloidosis with cardiomyopathy (ATTR-CM). The primary objectives were aimed at studying the safety and pharmacodynamics of this novel gene-based treatment modality. This episode dives into the nuances of the data, future directions for investigation, and future clinical implications.

Join CardioNerds co-founder Dr. Daniel Ambinder, episode lead Dr. Nidhi Patel, and expert faculty Dr. Keith Ferdinand as they discuss the BP ROAD trial.

The BP ROAD trial randomized 12,821 patients 50 years of age or older with type 2 diabetes, elevated systolic blood pressure, and an increased risk of cardiovascular disease to receive intensive treatment that targeted a systolic blood pressure of less than 120 mm Hg or standard treatment that targeted a systolic blood pressure of less than 140 mm Hg for up to 5 years. Investigators found a significant reduction of major cardiovascular events with intensive blood pressure lowering. This episode dives into the nuances of the data and clinical implications.
