Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace narrowed aortic valves that fail to properly open. Following this procedure, however, left ventricular (LV) hypertrophy and myocardial fibrosis persist and are linked to worse prognosis. Renin-angiotensin system (RAS) inhibition can protect against these risks and in response to … [Read more...] about Renin-angiotensin system inhibitors improve TAVR prognosis

Prognostic implication of myocardial injury during PCI vs CABG
Periprocedural myocardial infarction (PMI) is myocardial injury that occurs during revascularization procedures, such as percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). What remains unclear is the prognostic implications of periprocedural myocardial infarction and the extent of myonecrosis that is prognostically significant. In the … [Read more...] about Prognostic implication of myocardial injury during PCI vs CABG
Cardiac magnetic resonance imaging used to identify infarct-related arteries in NSTEMI patients
Non-ST-segment-elevated myocardial infarction (NSTEMI) patients often present with multivessel or non-significant coronary artery disease. This can complicate identification of the infarct-related artery (IRA), increasing the likelihood of revascularization of non-culprit arteries. https://youtu.be/WchARtkURiA A recently published study by Heitner et al. has … [Read more...] about Cardiac magnetic resonance imaging used to identify infarct-related arteries in NSTEMI patients
A strategy for predicting abnormal diastolic response to exercise in patients with dyspnea unable to perform an exercise test
The difficulties of diagnosing heart failure with preserved ejection fraction (HFpEF) are well known. In patients presenting with dyspnea, its presence can be confirmed by exercise testing. However, many patients are unable to perform adequate exercise testing, hence the need for a simpler clinical diagnostic test. Kosmala et al. describe such a diagnostic strategy that … [Read more...] about A strategy for predicting abnormal diastolic response to exercise in patients with dyspnea unable to perform an exercise test
Prognostic value of sodium balance in acute decompensated heart failure
In relation to natriuresis in the pathophysiology of heart failure, current guidelines focus on fluid balance and weight change. Despite the frequent use of these parameters as endpoints in major clinical trials, they have yet to be linked to meaningful clinical outcomes. Researchers in the ROSE-AHF trial suggest that this focus on fluid volume and weight change represents a … [Read more...] about Prognostic value of sodium balance in acute decompensated heart failure
