"Lao Liu, have you heard? Uncle Zhang from our community had a heart attack in the middle of the night a few days ago, but fortunately, his wife found out early and quickly dialed 120 to get his life back. ”
Lao Li is telling this thrilling story vividly, attracting old friends who are exercising around to stop and listen. "Oh, Uncle Zhang usually looks very tough, why did he suddenly have a heart attack? This illness came too suddenly!"
It is said that that night, as soon as Uncle Zhang lay down and was about to go to bed, he suddenly felt cold sweat all over his body, and he shouted that his chest was tight.
Seeing that his face was pale and his voice had changed, his wife knew that the situation was not good, so she quickly called the children and called an ambulance. The doctor said that a few minutes later, the consequences would be unimaginable. ”
"The heart attack is so dangerous, is there really no warning in advance?" Lao Liu clenched the fitness ball in his hand, and a trace of fear appeared in his heart. "I heard that before some heart attacks, there will be some abnormal manifestations when sleeping, such as sounding the alarm bell for us in advance!"
01. 4 nighttime signs before the onset of myocardial infarction
Cold sweat in the middle of the night: Heavy sweating at night without warning, especially when sweat soaks through clothing and wakes people up, can be a strong warning that a heart attack is about to occur.
Up to 70% of people with myocardial infarction experience these symptoms before the onset of the disease. Cold sweat stems from an emergency response caused by a disorder of the body's autonomic nervous system when the blood supply to the heart is severely insufficient.
Obstructed breathing, chest tightness and sleeplessness: If there is a persistent feeling of chest tightness before falling asleep or during sleep, such as a heavy object pressing on the chest, or accompanied by poor breathing, unable to lie flat, forced to sit up for relief, this may be caused by cardiovascular dysfunction in the pre-myocardial infarction.
Myocardial ischemia can lead to obstruction of venous return to the lungs, causing pulmonary edema, which in turn affects breathing. This abnormal chest tightness not only interferes with sleep, but may also be an early sign of a heart attack, and it is necessary to seek medical attention as soon as possible.
Mood swings, irritability: Before the onset of a myocardial infarction, some patients will experience unexplained emotional changes, such as irritability, anxiety, and even fear for no reason.
These mood swings may stem from indirect effects of insufficient oxygen supply to the heart on the central nervous system, or from the body's instinctive response to a potential crisis.
Nausea and vomiting, dizziness and discomfort: Nausea and vomiting caused by non-digestive diseases, especially accompanied by symptoms such as dizziness and palpitations, especially at night, may be one of the precursors of myocardial infarction.
Myocardial ischemia triggers vagus nerve excitation, which in turn leads to gastrointestinal reactions. At the same time, a lack of blood supply to the brain can also cause dizziness.
02. Myocardial infarction "favors" six high-risk groups
Smokers: Tobacco is like an "invisible killer" in blood vessels, destroying the vascular endothelium, inducing coronary spasm, and causing the myocardium to fall into ischemia predicament. Long-term smokers are like igniting a chronic poisonous fire around the heart, which can detonate a heart attack crisis at any time.
People who stay up late: The risk of heart attack in people who fall asleep after 24 o'clock is 62.8% higher than that of those who go to bed early. They are like runners running alone in the dark, their hearts are overloaded and they may collapse at any moment due to exhaustion.
Patients with high blood pressure: High blood pressure can lead to atherosclerosis, which affects the blood supply to the heart muscle. Under long-term high pressure, the heart is like a walker carrying a heavy mountain, and every step is accompanied by heavy wheezing, which may cause a myocardial infarction due to overwork at any time.
Diabetic patients: The oxygen-carrying capacity of red blood cells in diabetic patients is reduced, and the myocardium is prone to hypoxia. At the same time, glycophilic platelets have strong adhesion and are easy to form thrombosis, making coronary arteriosclerosis and myocardial infarction a shadow that is difficult to get rid of.
Stressed people: Many people in modern society struggle with the dual pressures of work and life. Long-term negative emotions are like invisible shackles that bind the heart, causing it to struggle with exhaustion and increase the risk of heart attack.
People who don't like to exercise: People who lack exercise can't consume the energy they consume effectively, which is converted into fat accumulation in the blood vessels, forming a hidden danger of blood clots. They are like snails sleeping in their comfort zone, seemingly comfortable, but in fact their hearts are at risk of being awakened by a heart attack.
03. Four major lifestyle habits to resist myocardial infarction
Low salt and low fat: Reducing salt intake can help control blood pressure and prevent arteriosclerosis, and limiting the intake of saturated fatty acids and choosing foods rich in unsaturated fatty acids can help lower cholesterol levels and maintain cardiovascular function.
Abundant fruits and vegetables and antioxidants: Increase your intake of fresh vegetables and fruits, which are rich in vitamins, minerals and antioxidants, which can resist oxidative stress and reduce inflammation in the blood vessels, which is beneficial in preventing heart attack.
Whole grains and beans provide dietary fiber: Moderate consumption of whole grains, brown rice, beans and other foods rich in dietary fiber can help reduce blood lipids, stabilize blood sugar, and reduce the predisposing factors of myocardial infarction.
Limit alcohol and sugar, refuse the sweet trap: limit the amount of alcohol to avoid excessive alcohol intake to the heart, control the intake of added sugar, especially avoid sugary drinks, to reduce the risk of diabetes, and indirectly prevent myocardial infarction.
Quit smoking completely: Nicotine, carbon monoxide and other harmful substances in tobacco directly damage the vascular endothelium, induce coronary artery spasm, and accelerate the process of atherosclerosis. Smoking cessation is one of the most direct and effective measures to prevent myocardial infarction.
Avoid staying up late: Try to maintain a fixed schedule and avoid late-night work and entertainment, so as to reduce the additional burden on the heart during the non-physiologically active period.
In the face of the silent "assassin of life" of heart attack, we are not helpless. By understanding the sleep warning signs before a heart attack and identifying whether we are in a high-risk group, we can effectively build a defense barrier to reduce the probability of heart attack and protect the health and tranquility of the heart.
