The banquet hall is very lively, happy in people’s faces, the most happy is Master Zhang, because today is his son’s wedding. He happily shuttled in the crowd, and guests and friends frequently raise a glass, pass each other cigarettes, his partner reminded him from time to time: “your high blood pressure, heart and bad, or less to drink, less smoke ……” “It’s okay, you see I’m fine, right? Today is the child’s wedding day, don’t spoil it!” Just when the wedding banquet was about to end, Master Zhang suddenly felt chest tightness, palpitations …… , then, sweating profusely, pale, people rushed him to the hospital, but because of myocardial infarction recurrence, although by the medical staff to rescue, he still left the world. Like some patients with myocardial infarction, Master Zhang was discharged from the hospital after the disappearance of clinical symptoms, thought he was cured, do not pay attention to the heart, heart care, “forget” smoking, drinking, so that the myocardial infarction killed a “shot back”, so that the family was caught off guard The family is in great distress. Recurrent myocardial infarction is also called reinfarction, that is, after the initial acute myocardial infarction hospitalization period, the original infarct area has healed after the recurrence, it is a common type of acute myocardial infarction in the elderly, accounting for about 12.8-25.0%; recurrence time is the highest within two years, accounting for 1/3- 1/2 of the total incidence of the fall, and a considerable number of cases The time of recurrence is the highest within two years, accounting for 1/3- 1/2 of the total incidence, and a considerable number of cases can be recurrent or multiple recurrence, the most can reach 6- 9 times or more. Experts point out that the mortality rate of reinfarction is significantly higher than that of the first acute myocardial infarction, and the more the number of reinfarctions and the shorter the interval, the higher the mortality rate. This is because, as a result of multiple infarctions, the area of necrotic non-contractile myocardium increases significantly, thus increasing the number of serious complications, such as heart failure, cardiogenic shock, or in more serious cases, fatal rhythm disorders such as ventricular fibrillation and heart rupture. Why is reinfarction? The reason is that after the clinical symptoms of acute myocardial infarction disappear, the pathological basis of —- coronary atherosclerosis and blood viscosity abnormalities do not decrease, and various risk factors may still be at work, and many triggers may reappear, so the risk of reinfarction The risk of reinfarction still exists. The following aspects are prone to reinfarction: 1, strenuous exercise: sudden strenuous exercise, sympathetic excitation, vasoconstriction, aggravating myocardial ischemia and hypoxia; 2, emotional excitement: great joy, anger, worry, etc. make the central nervous system and cardiovascular system in an unstable state, vasodilation and contraction function is greatly affected; 3, neglect to keep warm: when the temperature drops suddenly, do not pay attention to warmth, prompting strong vasoconstriction; coupled with Dry climate, reduced drinking water, low activity, resulting in thick blood, slow flow and induced re-infarction; 4, defecation force: do not pay attention to keep the bowel movement, defecation difficulty when holding the breath force, so that the abdominal pressure increases, blood pressure rises suddenly, increased myocardial oxygen consumption; 5, recreation is not moderate: all night long playing mahjong, playing cards, a long time in a state of tension, so that the body adrenaline secretion increased, blood pressure increases; such as then Calculation of win or lose, emotional ups and downs, so that myocardial oxygen consumption greatly increased; 6, the pursuit of stimulation: love to watch the thrilling athletic competition and the chase and fight of the thrilling film, television drama, and even to the fierce rhythm, lighting fast-changing ballroom dancing, so that they are in a thrilling atmosphere and strong sensory stimulation; 7, forgetting to drink: ethanol stimulates the central nervous system, causing vasospasm, increasing myocardial oxygen consumption; 8, Eating too much: craving for delicious food, overeating, increasing the burden on the heart; 9, laughing: laughing, sympathetic nerve overexcitation, increased adrenaline secretion, causing a rise in blood pressure; 10, excessive fatigue: do not pay attention to rest, physical and mental fatigue, increasing the burden on the heart; 11, indiscriminate intercourse: feel energetic, full of energy after the disease, unrestrained sexual life; 12, abrupt drug withdrawal: feel that the disease Stable, suddenly stop using all drugs without permission, causing the condition to rebound. These “sad” things, for the average person may not pose any great threat, but for patients who have suffered a myocardial infarction, the consequences are often very serious. Master Zhang excessive joy, wanton drinking, smoking, and overwork when hosting a wedding, resulting in joy and sadness.
