Clinical Trial | By Catino AB, Hubbard RA, Ky B et al.
BACKGROUND - Sunitinib, used widely in metastatic renal cell carcinoma, can result in hypertension, left ventricular dysfunction, and heart failure. However, the relationships between vascular function and cardiac dysfunction with sunitinib are poorly understood. METHODS AND RESULTS - In a multicenter prospective study of 84 metastatic renal cell carcinoma patients, echocardiography, arterial tonometry, and BN...

OBJECTIVES - The aim of this study was to investigate the influence of microvascular damage in one vessel territory on invasively measured physiological parameters in the other vessel, using a porcine microvascular damage model. BACKGROUND - Although fractional flow reserve (FFR)-guided decision-making for the nonculprit stenosis in patients with acute myocardial infarction has been reported to be better than angi...

BACKGROUND - Current guidelines recommend dual antiplatelet therapy (DAPT) of aspirin plus a P2Y12 inhibitor for at least 12 months after implantation of drug-eluting stents (DES) in patients with acute coronary syndrome. However, available data about the optimal duration of DAPT in patients with acute coronary syndrome undergoing percutaneous coronary intervention are scant. We aimed to investigate whether a 6-month duration...

BACKGROUND - MiStent is a drug-eluting stent with a fully absorbable polymer coating containing and embedding a microcrystalline form of sirolimus into the vessel wall. It was developed to overcome the limitation of current durable polymer drug-eluting stents eluting amorphous sirolimus. The clinical effect of MiStent sirolimus-eluting stent compared with a durable polymer drug-eluting stents has not been investigated in a large randomised ...
Original Research | By Lee SH, Song YB, Lee JM et al.
BACKGROUND - Whether side branch (SB) predilation before main vessel (MV) stenting is beneficial is uncertain, so we investigated the effects of SB predilation on procedural and long-term outcomes in coronary bifurcation lesions treated using the provisional approach.Methods and Results:A total of 1,083 patients with true bifurcation lesions undergoing percutaneous coronary intervention were evaluated. The primary outcome was a ma...
The Wait for High-Sensitivity Troponin Is Over—Proceed Cautiously
Since high-sensitivity troponin (hsTn) assays became available for clinical use in Europe in 2010, clinicians in the United States have been waiting eagerly for US Food and Drug Administration (FDA) approval. It is finally here. High-sensitivity troponin assays hold promise for earlier diagnosis of myocardial infarction (MI), a decrease in the time required to rule out MI, a reduction in sex bias in the diagnosis of MI, and an improvement ...
Expert Opinion | By MR Gimenez, P Badertscher, R Twerenbold et al.
In patients presenting with suspected myocardial infarction (MI), beyond the presence or absence of MI, 4 clinical variables seem to affect high-sensitivity cardiac troponin (hs-cTn) concentrations: age, renal dysfunction, time from chest pain onset, and sex.1 Among the 4 variables, sex has received the most attention, resulting in uncertainty about the need to abandon the 1 overall cutoff in favor of sex-specific cutoffs for hs-cTn in the diagnosis of...
Clinical Trial | By Giugliano RP, Keech A, Murphy SA et al.
IMPORTANCE - Current guidelines for atherosclerotic cardiovascular disease focus on high-intensity statins and targeting or using a threshold low-density lipoprotein cholesterol (LDL-C) level of less than 70 mg/dL for the highest-risk patients. Whether further reduction of LDL-C beyond these boundaries would be beneficial is unknown. OBJECTIVE - To compare outcomes of evolocumab vs placebo in patients ...

BACKGROUND - Canakinumab, a monoclonal antibody targeting interleukin-1β, reduces inflammation and cardiovascular event rates with no effect on lipid concentrations. However, it is uncertain which patient groups benefit the most from treatment and whether reductions in the inflammatory biomarker high-sensitivity C-reactive protein (hsCRP) correlate with clinical benefits for individual patients. METHODS - Th...
Similarities and differences in 2 contemporary postrandomization on-treatment analyses from the FOURIER trial (Further Cardiovascular Outcomes Research With PCSK9 Inhibition in Subjects With Elevated Risk) and CANTOS trial (Canakinumab Antiinflammatory Thrombosis Outcome Study) may provide insight into what factors drive reductions in cardiovascular mortality and all-cause mortality among patients with atherosclerosi...
