There is robust epidemiological evidence dating back to the original Framingham Heart Study from 1977 that indicates an important inverse relationship between high-density lipoprotein cholesterol (HDL-C) and risk of incident coronary artery disease (CAD). Despite this body of scientific information demonstrating that low levels of HDL-C are an independent predictor ...

Even when reperfusion therapy is applied as early as possible, survival and quality of life are compromised in a considerable number of patients with ST-segment elevation acute myocardial infarction. Some cell death following transient coronary occlusion occurs during reperfusion, due to poor handling of calcium in the sarcoplasmic reticulum-mitochondria system, ...

Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy for patients with ST-segment elevation myocardial infarction (STEMI). Effective and safe adjunct antithrombotic therapy is a major determinant for short- and long-term outcomes after primary PCI. Two separate studies have shown significant benefits vs conventional therapy for 2 recently approved ...

Since ischemic heart disease (IHD) is a major cause of mortality and heart failure, novel therapeutic strategies are expected to improve the clinical outcomes of patients with acute myocardial infarction. Brief episodes of ischemia/reperfusion performed at the onset of reperfusion can reduce infarct size; a phenomenon termed "ischemic postconditioning." Extensive ...

Staging of heart failure represents a major issue in clinical practice. In this setting, MOGE(S) classification has been designed to be similar to TNM used in oncology. Nevertheless, MOGE(S) nosology is far away from the key elements of TNM classification, as well as simplicity and clinical applicability. In fact, MOGE(S) ...

A major limitation of primary percutaneous coronary intervention (PPCI) for the treatment of ST-elevation myocardial infarction (STEMI) is impaired microvascular perfusion due to embolization and obstruction of microcirculation with thrombus. Manual thrombectomy has the potential to reduce distal embolization and improve microvascular perfusion. Clinical trials have shown mixed results regarding ...

Cell therapy for heart disease began clinically more than a decade ago. Since then, numerous trials have been performed, but the studies have been underpowered, focusing primarily on low-risk patients with a recent myocardial infarction. Many data have accumulated on surrogate endpoints such as ejection fraction, but few clinical conclusions ...

Coronary bifurcation lesions account for approximately 15% of all percutaneous coronary interventions (PCI) performed. Although clinical outcomes after PCI have been improved considerably, PCI of bifurcation lesions remains to be associated with adverse clinical events, when compared with non-bifurcation PCI. Therefore, several dedicated bifurcation devices have been developed to improve ...

Although high-sensitivity cardiac troponin (hs-cTn) substantially improves the early detection of myocardial injury, it lacks specificity for acute myocardial infarction (MI). In suspected non-ST-elevation MI, invasive coronary angiography (ICA) remains necessary to distinguish between acute MI and noncoronary myocardial disease (eg, myocarditis), unnecessarily subjecting the latter to ICA and associated ...

Numerous definitions have been proposed for the diagnosis of myocardial infarction (MI) after coronary revascularization. The universal definition for MI designates post procedural biomarker thresholds for defining percutaneous coronary intervention (PCI)-related MI (type 4a) and coronary artery bypass grafting (CABG)-related MI (type 5), which are of uncertain prognostic importance. In ...

Secondary hyperparathyroidism is an almost inevitable complication of advanced kidney failure. The introduction of the calcimimetic cinacalcet for the treatment of secondary hyperparathyroidism in patients on dialysis was based on its ability to reduce elevated levels of parathyroid hormone (PTH). Subsequent clinical studies confirmed the beneficial effects of cinacalcet on ...

The majority (70%) of coronary revascularizations concern patients with multivessel disease (MVD). Treatment options include medical therapy, percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). CABG surgery has been shown to improve survival compared with medical therapy. PCI relieves angina compared with medical therapy and is equivalent to ...

Endpoint selection is a critically important step in clinical trial design. It poses major challenges for investigators, regulators, and study sponsors, and it also has important clinical and practical implications for physicians and patients. Clinical outcomes of interest in heart failure trials include all-cause mortality, cause-specific mortality, relevant non-fatal morbidity ...

Procedure-related myocardial infarction (pMI) is directly associated with a coronary revascularization procedure, such as percutaneous coronary intervention (PCI) or CABG surgery. In contrast to spontaneous myocardial infarction (MI), the prognostic relevance of pMI is the subject of ongoing debate. Data from retrospective analyses of large, randomized clinical trials, and large, ...

Left ventricle (LV) remodeling after anterior wall myocardial infarction leads to increased LV volumes, myocardial stress, and, ultimately, heart failure (HF). Patients have high morbidity and mortality risk, and treatment remains limited. Percutaneous ventricular restoration (PVR) therapy using the Parachute device, a fluoropolymer membrane stretched over a nitinol conical frame, ...

A very large body of evidence-predominantly retrospective-suggests that revascularization is superior to optimal medical therapy in patients with a significant amount of 'hibernating' myocardium. Contemporary cardiological practice has embraced this standard of practice, as many centres worldwide place great emphasis upon the results of viability testing by non-invasive imaging techniques ...

The evaluation of ventricular function is a core component of 2-dimensional echocardiography (2DE). Given the known limitations of 2DE, a more accurate assessment of ventricular function has long been desired. Three-dimensional echocardiography (3DE) holds promise to fulfill this role while maintaining the same benefits of low cost, portability, and efficiency ...

We hypothesized that the insensitivity of the electrocardiogram in identifying acute circumflex occlusion would result in differences in the distribution of the infarct-related artery (IRA) between patients with non-ST-segment elevation myocardial infarction (NSTEMI) and STEMI enrolled in the Occluded Artery Trial. We also sought to evaluate the effect of percutaneous ...

Coronary heart disease (CHD) is the leading cause of death and disability worldwide. Despite current therapy, the morbidity and mortality for patients with CHD remains significant. The most significant manifestations of CHD arise from acute myocardial ischemia-reperfusion injury (IRI) in terms of cardiomyocyte death and its long-term consequences. As such, ...
