Just as you're back, come visit your cousin at the hospital—he's been admitted. On her way home, Xiao Mei suddenly got a call from her dad and had to head straight to the hospital to see her cousin. That evening, he seemed fine and even quite energetic. They made plans to catch up properly the next day.Little did she know that the next morning, she would be awakened by the devastating news of her cousin's death. A myocardial infarction had taken his life at just 32 years old.Obesity places immense strain on the cardiovascular system. Over time, atherosclerotic plaques form in the coronary arteries, narrowing or blocking the blood vessels. This leads to myocardial ischemia, oxygen deprivation, or necrosis, ultimately causing coronary heart disease. Xiao Mei's cousin succumbed to a myocardial infarction triggered by the rupture of an atherosclerotic plaque.
Three warning signs precede myocardial infarction
Myocardial infarction typically occurs acutely because underlying cardiovascular lesions already exist. When patients experience emotional stress or strenuous physical labor, the heart's workload increases, raising myocardial oxygen demand. With already hardened, narrowed coronary arteries and plaque detachment, the vessels cannot dilate sufficiently, causing myocardial ischemia.If plaque blockage causes vessel rupture, myocardial infarction ensues.
Though sudden in onset, myocardial infarction often presents precursors. Recognizing these symptoms may save lives.
1. Sudden chest pain accompanied by tightness, lasting over 15 minutes.
2. Experiencing palpitations, nausea, vomiting, shortness of breath, pallor, and restlessness.
3. Unexplained chest, back, or shoulder pain that occurs intermittently with varying durations. Such symptoms warrant immediate attention.
4. For obese individuals or those with high blood pressure, high blood sugar, or high cholesterol, stomach pain may signal early myocardial infarction.
5. Some patients experience intermittent toothaches lasting only minutes but recurring frequently.
6. Sudden anxiety-induced insomnia in someone without prior sleep issues is a strong warning sign of heart attack.
7. Unexpectedly rapid heartbeat lasting about 10 minutes, worsening during emotional stress or physical exertion.
8. Some patients report intermittent toothaches lasting only minutes but recurring frequently.
9. Sudden anxiety-induced insomnia in someone without prior sleep issues is a strong warning sign of heart attack.
7. Unexplained sudden heart palpitations lasting about 10 minutes, worsening during emotional stress or physical exertion.
8. Persistent fatigue and dizziness that does not improve with rest. Beyond these pre-event symptoms, three major warning signs indicate myocardial infarction risk:
The first warning sign is having underlying conditions that predispose one to myocardial infarction. Hypertension, hyperlipidemia, diabetes, and obesity are all foundational diseases that can trigger myocardial infarction. Additionally, smoking, staying up late, prolonged sedentary behavior, and unhealthy dietary habits are also contributing factors. If any of these conditions exist, the risk of myocardial infarction is elevated.
The second warning sign is a history of prior episodes. Some coronary heart disease patients have experienced angina attacks. If angina has occurred before, it must be taken seriously, as a subsequent episode could escalate into a myocardial infarction.
The third warning sign is that the infarction is already occurring. This is a critical moment—without immediate medical attention, the patient could lose their life.
If a heart attack occurs, or if symptoms suggest a possible heart attack, the patient must remain calm and take the following necessary steps.
If a heart attack occurs, the patient should lie down, as standing or emotional agitation can increase the burden on the heart.
If the attack happens at home, the patient should immediately take life-saving medication. Typically, this includes aspirin and nitroglycerin. Chewing and swallowing aspirin helps prevent blood clots from growing, while nitroglycerin dilates blood vessels to restore blood flow to the heart as much as possible.
Finally, call 911 immediately. The golden window for myocardial infarction emergency treatment is only 120 minutes. The sooner rescue begins, the better the patient's prognosis. Therefore, once symptoms of a heart attack appear, dial 911 for medical assistance without delay.
Why is the mortality rate for myocardial infarction so high?
The high fatality rate stems from the critical and unique location of the affected area.The heart continuously supplies blood to the entire body without pause, yet myocardial infarction directly disrupts this vital blood supply. Myocardial cells undergo necrosis due to ischemia and hypoxia. The longer this condition persists, the larger the necrotic area becomes, significantly increasing mortality rates.
Furthermore, myocardial infarction often occurs without warning signs, making prevention challenging.Moreover, its sudden onset means patients often have no idea when or where it will strike. Without prompt medical intervention, the fatality rate soars. How to Prevent Myocardial Infarction Preventing myocardial infarction requires addressing the root causes. Quit smoking: Among young and middle-aged adults with acute myocardial infarction, the smoking rate is 78.3%. Therefore, quitting smoking is crucial for prevention.
Ensure adequate sleep. Insufficient sleep or chronic sleep deprivation can disrupt autonomic nervous system function, increasing susceptibility to myocardial infarction and arrhythmias.
Practice stress reduction. Persistent mental tension elevates catecholamine hormone levels in the blood, which can damage blood vessels and trigger myocardial infarction and hypertension.
Maintain regular eating habits. Unhealthy dietary patterns increase risks of hypertension, diabetes, and hyperlipidemia, making balanced nutrition essential.
Minimize emotional fluctuations. Individuals with unstable or volatile emotions experience the greatest impact on blood vessels and blood pressure, potentially triggering hypertension and myocardial infarction—in severe cases, leading to "broken heart syndrome."
Commit to exercise. Long-term physical activity significantly enhances the heart's reserve capacity, protecting blood vessels and the heart even during strenuous exertion.
Maintain a healthy weight. Obesity increases the risk of hyperlipidemia, hypertension, and diabetes. These conditions further exacerbate cardiovascular disease, accelerating blockages within heart vessels. This narrowing of coronary arteries can ultimately lead to myocardial infarction.
