AIMS: Enhanced heart rate is a compensatory mechanism in chronic heart failure (CHF), preserving cardiac output, but at the cost of increased left ventricular (LV) oxygen consumption and impaired diastolic function. Heart rate reduction (HRR) induced by the If current inhibitor ivabradine prevents LV systolic dysfunction in CHF, but whether ...

It is unclear whether intracoronary (IC) bolus administration of glycoprotein IIb/IIIa inhibitors (GPIs) during percutaneous coronary intervention (PCI) in patients with acute coronary syndromes is superior to intravenous (IV) administration. We conducted a meta-analysis of randomized controlled trials (RCTs) to compare the effects of IC and IV administrations of GPIs ...

Percutaneous coronary stenting is synonymous with dual antiplatelet therapy, ranging from four weeks to lifelong. However, even short-term (four weeks) therapy with aspirin and thienopyridines is occasionally contraindicated. No study has ever appraised very short-term dual antiplatelet therapy after stenting. We thus aimed to exploit the pro-healing features of the ...

Despite observations suggesting a benefit for late opening of totally occluded infarct-related arteries after myocardial infarction, the Occluded Artery Trial (OAT) demonstrated no reduction in the composite of death, reinfarction, and class IV heart failure over a 2.9-year mean follow-up. Follow-up was extended to determine whether late trends would favor ...

Atrioventricular conduction prolongation (AVCP) in cardiac pacing is measurable and results primarily from delayed atrial conduction. Noninvasive methods for measuring atrial conduction are lacking. Accordingly, AVCP was used to estimate atrial conduction and investigate its role on the paced atrioventricular delay (pAVD) during biventricular pacing (BiVP) optimization. Retrospective analysis of ...

In the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT), a randomized, double-blind, practice-based, active-control, comparative effectiveness trial in high-risk hypertensive participants, risk of new-onset heart failure (HF) was higher in the amlodipine (2.5-10 mg/d) and lisinopril (10-40 mg/d) arms compared with the chlorthalidone (12.5-25 mg/d) arm. Similar ...

Cardiogenic shock still has a grave prognosis. We present the recent advances in mechanical circulatory support (MCS) for the treatment of refractory cardiogenic shock. The contraindications for short-term MCS in rapid-onset cardiogenic shock are becoming fewer and the threshold for its application has been progressively lowered. Short-term MCS is increasingly ...

Whether concentric left ventricular (LV) hypertrophy (LVH) is a common precursor to depressed LV ejection fraction (EF) in humans is uncertain. From 1992 through 1994, 555 patients at our institution underwent echocardiography and had LVH (posterior or septal wall thickness ≥1.3 cm or concentric LVH noted) and normal LVEF. Of ...

Randomized controlled trials (RCTs) are the centerpiece of evidence-based medicine. However, because of the limited follow-up, additional evidence on the long-term consequences of the outcomes used in trials is commonly required for clinical and policy decision making. This article provides insights into the importance and challenges of using such evidence ...

There has been growing evidence that the Purkinje network plays a pivotal role in both the initiation and perpetuation of ventricular fibrillation (VF). A triggering ventricular premature beat (VPB) with a short-coupling interval could arise from either the right or left Purkinje system in patients with polymorphic ventricular tachycardia (VT) ...

Penetrating cardiac trauma carries high mortality rates. It has been commonly associated with stabbing, but increasing urban violence has led to growing numbers of gunshot heart wounds. The latter have higher mortality rates among penetrating cardiac injuries and may affect multiple heart chambers, with mortality rates even higher. We report ...

Prolonged ischemia causes cellular necrosis and myocardial infarction (MI) via intracellular calcium (Ca(2+)) overload. Manganese-enhanced MRI indirectly assesses Ca(2+) influx movement in vivo as manganese (Mn(2+)) is a Ca(2+) analog. To characterize myocardial Mn(2+) efflux properties, T(1)-mapping manganese-enhanced MRI studies were performed on adult male C57Bl/6 mice in which Ca(2+) ...
