Optimal management of patients with acute myocardial infarction (MI) due to critical stenosis of an unprotected left main coronary artery (ULMCA) is not established. However, data from observational studies and registries encourage to perform percutaneous coronary intervention (PCI) in high risk patients. We investigated gender-related discrepancies, clinical course and prognosis ...

Echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. It is the most frequently used cardiovascular diagnostic test after electrocardiography and chest X-ray. However, in a patient with acute chest pain, Transthoracic Echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation ...

A modern concept considers acute coronary syndrome as an autoinflammatory disorder. From the onset to the healing stage, an endless inflammation has been presented with complex, multiple cross-talk mechanisms at the molecular, cellular, and organ levels. Inflammatory response following acute myocardial infarction has been well documented since the 1940s and ...

Whilst advances in reperfusion therapies have reduced early mortality from acute myocardial infarction, heart failure remains a common complication, and may develop very early or long after the acute event. Reperfusion itself leads to further tissue damage, a process described as ischaemia-reperfusion-injury (IRI), which contributes up to 50% of the ...

Ischemic heart disease (IHD) is the leading cause of death and disability worldwide. The major pathological consequences of IHD arise from the detrimental effects of acute ischemia-reperfusion injury (IRI) on the myocardium. Therefore, in order to improve clinical outcomes in patients with IHD, novel therapeutic strategies are required to protect ...
