Be careful when exercising after being tired or staying up late, and beware of myocardial infarction!

Don’t do strenuous exercise rashly after being extremely tired or staying up late! A 53-year-old male engineer named Lin went out for a run on the weekend after working overtime for a week. Unexpectedly, he suddenly suffered a myocardial infarction and fell to the ground. Fortunately, he was immediately found by the public, who performed cardiopulmonary resuscitation and called 119 for medical treatment. After a cardiac catheterization surgery to open the blood vessels and place a stent, his life was successfully saved. He recovered well after the operation and has no sequelae.

Don’t exercise randomly after being tired or staying up late! Beware of acute heart disease

Dr. Huang Hongru, a cardiologist at Guangtian General Hospital, said that with the popularity of sports health care in recent years, the number of patients seeking medical treatment due to myocardial infarction caused by sudden and intense exercise has also increased significantly. In this regard, it is recommended that people increase the intensity of exercise gradually when exercising, and do not immediately engage in strenuous exercise or competition without warming up.

In particular, after being extremely tired or staying up late, for example, working overtime, or staying up all night watching TV series or game broadcasts, you should be particularly careful after the body has accumulated fatigue. You should avoid immediately engaging in strenuous exercise (sprint running, playing in a ball game, or doing high-intensity physical fitness exercises) and other activities; this will increase the chance of rupture of the blood vessel wall due to instantaneous strenuous exercise, thereby increasing the risk of acute heart disease.

Dr. Huang Hongru pointed out that the human heart has three main coronary arteries, which are responsible for providing blood flow and nutrition to the heart. The three main coronary arteries are: the left anterior descending coronary artery, the left circumflex artery, and the right coronary artery. In the case of Mr. Lin, catheter coronary angiography showed that the proximal end of the left anterior descending coronary artery, the most important of his three cardiovascular arteries and responsible for about 50% of the blood flow, was completely blocked, and the right coronary artery was also blocked. This will cause cardiac ischemia, leading to fatal ventricular fibrillation and shock. If you are not careful, there is a high risk of death.

Don’t miss the golden life-saving time for acute myocardial infarction! Unblock blood vessels within 6 hours and reduce sequelae

Dr. Huang Hongru reminds that the golden life-saving time for acute myocardial infarction is to clear the blood vessels as soon as possible within 6 hours after the occurrence of myocardial infarction, and the sooner the better. He shared that he had encountered patients in clinical practice who delayed treatment, and during the process suffered from acute myocardial infarction, vascular blockage, myocardial ischemia, and severe arrhythmia (ventricular tachycardia, ventricular fibrillation). As a result, the heart was unable to effectively pump blood to the brain and other important organs, causing damage to body functions; in particular, the brain was ischemic and hypoxic, resulting in permanent neurological damage, and the patient has to rely on family care to live to this day.

Fortunately, Mr. Lin in the above case received prompt medical treatment, and the two blood vessels were urgently unblocked. A stent was placed in the left anterior descending coronary artery, temporarily alleviating the problem. Mr. Lin has no neurological problems after the treatment.

【Doctor's Tips】:

Finally, Dr. Huang Hongru also reminded that people who smoke, have high blood sugar, high blood pressure, high blood lipids, or have a family history are all at high risk of acute myocardial infarction. What the above groups should be aware of is that although myocardial infarction generally occurs more frequently in autumn and winter, they should still pay appropriate attention to its hazards in summer. If you want to actively prevent myocardial infarction, the simplest and most practical way is to properly control the three high problems, actively quit smoking, and develop regular and moderate exercise habits; and it is best to avoid strenuous exercise when you are physically and mentally weak, such as staying up late, tired, etc.; and regularly undergoing cardiovascular health checks is the key to effectively preventing myocardial infarction.
