How to detect myocardial ischemia? All of these methods work!

Patients with myocardial ischemia are mainly elderly people, and the harm caused to the body when the disease occurs is immeasurable. In general, this disease can be detected by electrocardiogram, echocardiogram, X-ray examination, coronary angiography, cardiac catheterization and other methods.

Electrocardiogram : Most patients are found to have abnormalities, which may manifest as various arrhythmias, the most common of which are atrial fibrillation, frequent multifocal premature ventricular contractions, sinus tachycardia and left bundle branch block. There are often ST-T abnormalities and pathological Q waves of old myocardial infarction.

Echocardiogram : Examination shows general enlargement of the patient's heart, often mainly left ventricular enlargement, with increased ventricular cavity diameter at end-diastole and end-systole, increased end-diastolic and end-systolic volumes, decreased left ventricular ejection fraction, and multi-segmental ventricular wall motion stiffness, weakening or disappearance. Patients with progressive heart failure may also develop right ventricular enlargement and pericardial effusion.

X-ray examination: Chest X-ray examination of patients with congestive ischemic cardiomyopathy may show signs of global cardiac enlargement or left ventricular enlargement, and may also have pulmonary interstitial edema, pulmonary congestion, alveolar edema, and pleural effusion. Aortic and coronary artery calcifications are sometimes found.

Coronary angiography: Patients often have multiple vascular stenosis of more than 70%. According to foreign statistics, about 71% have 3-vessel lesions, 27% have 2-vessel lesions, and only 2% have a single-vessel lesion. 79% had left circumflex artery disease, 88% had right coronary artery disease, and 100% had left anterior descending artery disease.

Cardiac catheterization: The patient's left atrial pressure, left ventricular end-diastolic pressure and pulmonary artery wedge pressure are increased. Examination may reveal local or diffuse multi-segmental and multi-regional ventricular wall motion abnormalities, significantly reduced left ventricular ejection fraction, mitral regurgitation, etc.

Ventricular radionuclide angiography : The examination showed enlarged cardiac chambers, ventricular wall motion disorders and decreased ejection fraction. Myocardial imaging can reveal areas of abnormal myocardial radionuclide perfusion in multiple segments.

The above is an introduction to the examination methods for myocardial ischemia in the elderly. When the elderly suffer from this disease, their children should pay more attention to their physical health and help them develop good living habits. You should also pay attention to adjusting your diet. Talk to the elderly often, take them for walks and stretch their muscles. These are very beneficial for the elderly.
