Angina pectoris and chest pain
What is it?
Angina pectoris is a pain or a kind of 'weight' that occurs in the chest and radiates to the surrounding areas (arms, neck, back and even jaw). It is a symptom of the heart that occurs as a result of a lack of oxygen caused by a blockage of the coronary arteries (arteries that bring oxygenated blood to the heart).
Which are the symptoms?
Angina pectoris generally has a duration of 5-10 minutes, arising during and immediately after exertion (exertional angina) or even at rest, immediately after eating (postprandial angina), with cold (frigid angina) or in the first hours of physical activity (warm-up). In some rare cases, in generally younger patients, angina may occur only at rest and during sleep, typically between 1:00 and 5:00 a.m. (Prinzmetal angina). Symptoms may be a sign of poor blood supply to the heart (ischemia). This is usually caused by significant narrowing of the arteries that supply the coronary arteries due to the presence of atherosclerotic plaques obstructing flow (in classic exertional angina); or by vasoconstriction of the coronary arteries on plaques that are not very critical (mixed angina); or by severe vascostriction of the coronary arteries that are free of atheroclerotic plaques (coronary spasm in Prinzmetal's angina). Finally, angina may be due to a functional/anatomical alteration of the small capillaries of the microcirculation of the heart (microvascular angina) that lie downstream of the coronary circulation.
- chest discomfort in the center of the chest at exertion or at rest
- sense of constriction, oppression, closure in the throat, which can be radiated to the jaw and even to the teeth
- deep discomfort in the shoulders (interscapularis) and sometimes in the arms on the lower side and the last two-three fingers of the hand (usually left)
- stomach pain on exertion or even at rest (in the epigastrium), which can be confused with a gastritis or indigestion
How is it diagnosed?
Cardiologist examination with echocardiogram taking.
Noninvasive investigation methods:
- physical stress test;
- stress echocardiography;
- myocardial perfusion scintigraphy after stimulation (physical stress, drugs with dipyridamole as active ingredient);
Cardiologist examination helps to perform general clinical evaluation and calculate cardiovascular risk factors (probability of connection of thoracic pain with the heart).
Coronarography is applied only when noninvasive examination has revealed the signs of incomplete heart blood supply, namely:
- physical stress shows revealed changes in the electrocardiogram;
- myocardial scintigraphy shows areas that do not receive radioactive tracers after the patient was physically loaded;
- stress echocardiography shows myocardial segments that do not move after physical or pharmacological stress.
