Use of Dynamic Myocardial Imaging in the Evaluation of Heart Failure With Preserved Ejection Fraction Provides Prognostic Value
A study published in JACC: Cardiovascular Imaging has shown that both left ventricular systolic and diastolic reserves contribute to risk prediction in Heart Failure With Preserved Ejection Fraction (HFpEF). Therefore, the inclusion of the exertional assessment of left ventricular function to diagnostic algorithms may improve the prognostication process in this disease condition. Continue reading
Prior Cerebrovascular Disease: A Key Factor In The Assessment for Optimal Left Main Coronary Artery Revascularization Strategy Results From the EXCEL Trial
A study conducted by Dr. Gregg W.Stone and his colleagues from Columbia University Medical Center demonstrated that patients with left main coronary artery disease (LMCAD) and prior cerebrovascular disease (CEVD) compared with those without CEVD have higher rates of stroke and reduced event-free survival after revascularization. In their publication in JACC: Cardiovascular Interventions, they stated that PCI need not be a priori preferred over CABG for LMCAD in patients with known CEVD. Patients with CEVD should undergo evaluation for both PCI and CABG, with careful consideration of comorbidities, the likelihood of safely achieving complete revascularization, and patient preferences in order to determine the optimal coronary revascularization strategy.

2018: Cardiology News at A Glance Most important trials published in 2018
COAPT trial
This prospective, multicenter, open-label, randomized trial aimed to assess the use of transcatheter mitral valve repair in heart failure (HF) patients with mitral regurgitation due to left ventricular dysfunction. A total of 614 patients were randomized to either receiving guideline-directed medical therapy (GDMT) alone or GDMT in addition to transcatheter mitral-valve repair. The primary efficacy endpoint was all hospitalizations due to heart failure at 24 months of follow-up, while the primary safety endpoint was freedom from device-related complications at 12 months of follow-up. The study showed that the device group had a lower risk of hospitalization for HF (HR 0.53, 95% CI 0.4-0.7) and all-cause mortality (HR 0.62, 95% CI 0.46-0.82) at 24 months. Moreover, the rate of freedom from device complications at 12 months was 96.6% which exceeded the prespecified safety threshold. Continue reading
