Cerebral infarction and heart attack are usually caused by bad living habits, atrial fibrillation, obesity, high blood pressure or high blood lipids. With age, the incidence of cerebral infarction and heart attack will gradually increase, so the elderly need to have regular medical checkups to detect the problem in time and treat it as early as possible. 1. Bad habits: Bad habits such as staying up late, high-fat diet, smoking, emotional anxiety and lack of exercise in daily life are more likely to damage blood vessels and lead to atherosclerosis, which can lead to heart attack and cerebral infarction. 2. Atrial fibrillation: patients with atrial fibrillation are more likely to form blood clots in the heart, and after the blood clots are dislodged, they will enter the aorta from the heart and enter all parts of the blood vessels along with the blood circulation. If it enters the cerebral blood vessels and cardiovascular vessels and causes blood vessel blockage, it will cause cerebral infarction and heart infarction. 3. Obesity: Obesity and overweight patients easily lead to the accumulation of fat in the body, thus blocking the cardiovascular and cerebral blood vessels, and with the development of time the blockage is gradually serious, and it is easy to induce cerebral infarction and heart attack. 4. Hypertension or hyperlipidemia: if patients with hypertension or hyperlipidemia don’t pay attention to standardized medication, blood pressure or blood lipid exceeds the normal range, it will lead to arterial damage caused by atherosclerosis. With the development of atherosclerosis gradually caused by the narrowing of the lumen or even closed, will eventually cause cerebral infarction and heart attack. Cerebral infarction and heart attack are all caused by atherosclerosis of blood vessel occlusion, with the age of cerebral infarction and the incidence of heart attack probability will gradually increase, it is recommended that the elderly regularly to the hospital for medical examination, timely detection of problems and treatment, to avoid delayed aggravation of the symptoms of the disease caused by the adverse consequences.
