The DAPT SHOCK AMI trial is the first major study to evaluate antiplatelet therapy specifically in patients with cardiogenic shock (CS) following acute myocardial infarction (AMI). It compares initial treatment strategies using cangrelor versus crushed ticagrelor. Early and potent platelet inhibition is critical for restoring microvascular reperfusion in this high-risk population. Previous randomized trials have excluded these patients, leaving a gap in evidence for optimal antiplatelet manageme...

The ODYSSEY-HCM trial found that mavacamten did not significantly improve exercise capacity or patient-reported outcomes in individuals with symptomatic nonobstructive hypertrophic cardiomyopathy. Safety concerns emerged, including more frequent reductions in ejection fraction and treatment interruptions among those receiving mavacamten. The trial's limited diversity and short duration raise questions about the generalizability and long-term implications of the findings. Despite the lack of appr...

Adverse pregnancy outcomes (APOs), affecting up to 20% of pregnancies, serve as early indicators of a woman's future cardiovascular risk and should be treated as critical markers in preventive care. Pregnancy offers a unique opportunity—a "window"—to identify and address cardiovascular vulnerabilities, making routine screening for heart health essential at every clinical encounter. Long-term monitoring beyond the postpartum period is vital, as cardiovascular risks persist and evolve over time. I...

Cohort studies have provided robust data on cardiovascular risk factors, forming the basis for predictive models like the Pooled Cohort Equations and PREVENT. Clinical trials confirm that treating these risk factors effectively reduces cardiovascular events. Over the past 50 years, age-adjusted mortality from acute myocardial infarction has dropped by 89%, reflecting major progress. To advance further, we must consider integrating imaging to identify those at highest risk, using risk factors to ...

The menopause transition marks a pivotal period of cardiometabolic change that significantly elevates cardiovascular (CV) risk in women. Despite its clinical importance, this phase remains underrecognized in CV risk assessment, contributing to a profound knowledge gap. Enhancing clinician education and fostering multidisciplinary collaboration are essential to delivering individualized care that addresses both symptom burden and long-term CV outcomes. By prioritizing this life stage, we can impr...

Chronic Total Occlusion Percutaneous Coronary Intervention (CTO PCI) is a procedure used to open coronary arteries that have been completely blocked for an extended period. It offers benefits like reduced angina and improved quality of life but carries risks such as vessel injury, heart attack, and procedural failure. Before considering CTO PCI, physicians typically optimize patients on anti-anginal medications—such as beta-blockers, nitrates, and calcium channel blockers—to manage symptoms and ...

While blood thinners like warfarin and direct oral anticoagulants (DOACs) remain the standard for stroke prophylaxis, left atrial appendage occlusion (LAAO) devices offer a non-pharmacologic alternative for patients at high bleeding risk. Recent trials have shown that LAAO can be as effective as anticoagulants in preventing stroke and may be a viable option, especially for patients who cannot tolerate long-term anticoagulation. In this interview, Drs. Anthony N. DeMaria and Dhanunjaya Lakkireddy...

Persistent symptoms after an acute pulmonary embolism (PE) may indicate post-pulmonary embolism syndrome (PPES), a condition affecting up to 50% of patients. The most important consideration in managing PPES is to carefully evaluate and differentiate it from other potential causes of ongoing shortness of breath, particularly chronic thromboembolic pulmonary hypertension (CTEPH), which requires targeted treatment. How can clinicians best differentiate between PPES and other causes of persistent s...

Palliative care supports heart failure patients by guiding complex medical decisions, managing symptoms, and enhancing quality of life. Despite being a guideline-recommended therapy, it remains underused—referrals are 45% lower for heart failure patients than for cancer patients with similar prognoses. Collaboration between cardiology and palliative care teams ensures that patients and caregivers receive goal-aligned care and the best possible quality of life. In this interview, Dr. Mary Norine ...

Recent clinical trials demonstrate that intensive blood pressure lowering—targeting systolic levels below 120 mm Hg—can significantly reduce cardiovascular events and mortality, even among older adults, individuals with diabetes, and those with chronic kidney disease. This challenges the long-standing belief that looser blood pressure targets are safer for older patients, showing instead that with proper monitoring, tighter control offers substantial net benefits for most high-risk groups. In th...

Rapid emergency medical services transport to a percutaneous coronary intervention (PCI)-capable hospital is critical for timely intervention and management of life-threatening arrhythmias in ST-elevation myocardial infarction patients. Upon emergency room arrival, immediate transfer to the cath lab is essential to restore perfusion and improve both short- and long-term cardiovascular outcomes, as recommended by clinical guidelines. Interventional cardiologists must also be adept at managing cul...

Heart failure arises when the heart is unable to pump or fill with blood effectively. In the cardiac catheterization lab, we have the unique ability to directly measure the physiological abnormalities underlying this condition, making it the gold standard for diagnosing heart failure. While not every patient requires heart catheterization, it is often essential for those with heart failure with preserved ejection fraction (HFpEF). This is because noninvasive tests, which are commonly used, frequ...

The SOUL trial demonstrated that in patients with type 2 diabetes (T2DM) and established atherosclerotic cardiovascular disease (ASCVD), chronic kidney disease (CKD), or both, treatment with oral semaglutide significantly reduced the risk of major adverse cardiovascular events (MACE) compared to placebo—without an increase in serious adverse events. These findings position oral semaglutide as a compelling option with cardiovascular benefits consistent with those seen in injectable GLP-1 receptor...
