coronariennes

Coronariennes refers to things pertaining to the coronary arteries of the heart. In French medical usage, coronarienne is an adjective (plural coronariennes) related to the arteries that supply the myocardium, and it is commonly found in phrases such as maladies coronariennes or artères coronariennes. The term is largely replaced in English by coronary or coronary arteries.

Anatomy: The coronary arteries arise from the base of the aorta and supply oxygenated blood to the heart muscle. The main vessels are the left coronary artery, which divides into the left anterior descending and the left circumflex arteries, and the right coronary artery. Their branches form a network that nourishes the walls of the cardiac chambers.

Pathologies: Coronary disease encompasses conditions caused by reduced blood flow through the coronaries, principally atherosclerotic plaque buildup. This can cause stable or unstable angina, myocardial infarction, and, with extensive disease, heart failure. Other coronarienne-related conditions include vasospasm and congenital anomalies of the coronary arteries.

Diagnostics and treatment: Evaluation relies on clinical assessment, electrocardiography, cardiac biomarkers such as troponin, imaging (echocardiography, CT angiography), and invasive coronary angiography. Treatments aim to restore or improve blood flow and reduce risk factors: antiplatelet therapy (for example aspirin), statins, antihypertensives, and lifestyle modifications. Revascularization with percutaneous coronary intervention or coronary artery bypass grafting may be indicated depending on disease extent and symptoms.
