Angina pectoris - Acute coronary syndrome without ST elevation

High urgency
Very commonModerately severe

Disease caused by a reduction in the blood supply to an area of the heart. The reduced supply of oxygenated blood leads to an imbalance in the supply and consumption of oxygen by heart muscle cells, resulting in damage.

The most common cause is narrowing of the blood vessels due to atherosclerosis, triggered by the accumulation of cardiovascular risk factors such as smoking, hypertension, diabetes, cholesterol, etc.

It typically presents as oppressive chest pain with sweating, nausea, vomiting, shortness of breath, pain in the arms and/or neck.

The diagnosis is made clinically by interview and physical examination. It is confirmed by an electrocardiogram and a blood test.

The aim of treatment is to prevent the formation of clots that can block the blood vessel and to dilate the vessel to improve blood flow. Anti-aggregants, vasodilators and drugs to reduce oxygen consumption in the heart muscle are used.

This is a serious condition that requires immediate medical attention.
