[Giant aneurysm of the right coronary artery: an unusual treatment].

Coronary artery aneurysm (CAA) is an uncommon disease observed in only 0.15-4.9% of patients undergoing coronary angiography.

Pathophysiology of Atherosclerotic Plaque Development.

Cardiovascular diseases and in particular coronary atherosclerotic disease are the leading cause of mortality and morbidity in the industrialized countries. Coronary atherosclerosis has been recognized for over a century and it was the subject of various studies. Pathophysiological studies have unravelled the interactions of molecular and cellular elements involved in atherogenesis; during the last decades the basic research has focused on the study of the instability of atherosclerotic plaque.

New Anti-Anginal Drugs: Ranolazine.

Chronic angina represents a condition that impairs quality of life and is associated with decreased life expectancy in the industrialized countries. Current therapies that reduce angina frequency include old drugs such as nitrates, β -blockers and calcium antagonists. Several new investigational drugs are being tested for the treatment of chronic angina.

Ticagrelor: a novel drug for an old problem.

Cardiovascular disease and in particular, acute coronary syndromes are one of the principle causes of death in the industrialized countries. In the setting of acute coronary syndromes (both ST - segment or non ST - segment elevation myocardial infarction), platelets aggregation plays a key and central role in their development. Platelets are the mediators of hemostasis at sites of vascular injury, but they also mediate pathologic thrombosis; activated platelets stimulate thrombus formation in response to rupture of an atherosclerotic plaque or endothelial cell erosion promoting atherothrombotic disease.

Novel biomarkers in the diagnosis of acute coronary syndromes: the role of circulating miRNAs.

Cardiovascular disease, in particular acute coronary syndromes (ACS), is still one of the leading causes of death in industrialized countries. ACS including ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UA) are associated with lower mortality if diagnosed early. The diagnosis is based on clinical symptoms, ECG and circulating biomarker-level changes.

Aortic counterpulsation in cardiogenic shock during acute myocardial infarction.

Intra-aortic balloon counterpulsation is the most widely used form of mechanical hemodynamic support in the setting of cardiogenic shock due to ST-segment elevation myocardial infarction (STEMI). Intra-aortic balloon pump (IABP) is also strongly recommended (class 1b) in the current European guidelines for treatment of STEMI. The evidence of a possible benefit of IABP in this setting is based mainly on registry data and a few randomized trials.

Ranolazine: effects on ischemic heart.

Coronary artery disease is the major cause of mortality and morbidity in the industrialized countries; in the United States of America and in Europe, it is responsible for one of every six deaths per year. In the setting of ischemic heart disease, angina pectoris and chest pain, in particular, are the major causes of emergency department accesses. Angina pectoris is a clinical syndrome characterized by discomfort typically in the chest, neck, chin and left arm induced by physical exertion, emotional stress and cold and is relieved by rest or by taking of nitrates.

Intracoronary injection of glycoprotein IIb/IIIa, abciximab, as adjuvant therapy in primary coronary intervention.

Acute coronary syndromes and, in paticular, ST - segment elevation myocardial infarction are the principle causes or mortality and morbidity in the industrialized countries. The manadgement of acute myocadial infarction is much debated in the literature; primary percutaneous coronary intervention is the treatment of choice. In the recent years there has been an increasing interest in the concept of adjunctive pharmacological therapy to improve outcomes in primary percutaneous coronary intervention.

Levosimendan preoperative.

During the last years an increasing number of patients with high perioperative risk and decreased left ventricular function are referred to cardiac and non-cardiac surgery. In this subgroup of patients, heart failure is the major cause of perioperative morbidity and mortality. In order to prevent and treat this type of complications several therapeutic attempts have been tried involving intra aortic balloon pump and inotropic agents infusion (such as beta-adrenergic agonists and phosphodiesterase inhibitors) Levosimendan is new inotropic agent; it is a calcium-sensitising inotropic agent and a vasodilator used in the treatment of heart failure.

Association of long QT syndrome loci and cardiac events among patients treated with beta-blockers.

Context: Data on the efficacy of beta-blockers in the 3 most common genetic long QT syndrome (LQTS) loci are limited.

Objective: To describe and assess outcome in a large systematically genotyped population of beta-blocker-treated LQTS patients.

Design, Setting, And Patients: Consecutive LQTS-genotyped patients (n = 335) in Italy treated with beta-blockers for an average of 5 years.
