What are the complications of myocardial infarction in the elderly?

summary

In the popular science book myocardial infarction and myocardial rehabilitation, Professor Ding Rongjing introduced that myocardial infarction is one of the most dangerous cardiovascular diseases, and it is also a major disease affecting the healthy life of Chinese residents. There may be several common complications after the occurrence of myocardial infarction, which should be paid attention to by patients and their families.

What are the complications of myocardial infarction in the elderly?

Cardiac rupture: it accounts for about 3% - 13% of the fatal cases. It often occurs within 1-2 weeks after myocardial infarction. The reason is that the infarct area loses elasticity, myocardial necrosis, neutrophils and monocytes release hydrolase, which leads to cardiac wall rupture. Ventricular aneurysm: about 10-38% of infarction cases. It may occur in the early stage of infarction or the healing stage of fibrosis. The infarcted myocardium or scar tissue, under the action of intraventricular pressure, swells outward to form ventricular aneurysm. Ventricular aneurysm can be secondary to mural thrombosis, arrhythmia and cardiac insufficiency.

Mural thrombus: more common in left ventricle. Because of the rough intima of infarct area, the vortex at the aneurysm and ventricular fibrillation, the thrombosis can be induced, which can fall off with the contraction and relaxation of the heart and cause the embolism of the arterial system. Arrhythmia: myocardial infarction involves the conduction system, causing conduction disorders, some can lead to cardiac arrest, sudden death. The most common cause of death is the loss of myocardial contractility in infarcted area, which leads to left, right or total heart failure.

Acute pericarditis: transmural infarction, often occurs after myocardial infarction serous or serous cellulosic pericarditis. About 15% of myocardial infarction, often occurs in 2-4 days after myocardial infarction, cardiogenic shock: about 10% - 20% of myocardial infarction. When the infarct size is more than 40%, the myocardial contractility is extremely weakened and the blood output is significantly reduced, which can cause cardiogenic shock and lead to death.

matters needing attention

The above is the content of the complications of myocardial infarction in the elderly. The elderly with this disease must take measures to prevent the complications. The complications of myocardial infarction may lead to the death of patients, so when they find that they have the precursor of myocardial infarction, they should immediately go to the hospital for health examination. When there is no life danger, they can be discharged.
