Four characteristics of myocardial infarction in women

Myocardial infarction is relatively common in clinical practice, and the problem of myocardial infarction is also very serious. Many patients experience myocardial infarction suddenly, so it is easy to miss the best time for treatment. Therefore, people should also pay attention to observe some signal prompts in their body. The probability of women suffering from myocardial infarction is also relatively high. So what are the four major characteristics of myocardial infarction in women?

1. The age of onset is relatively old, and most patients are elderly women. The incidence of acute myocardial infarction increases significantly with age, and is closely related to the onset of coronary heart disease. Due to the protective effect of estrogen on women's cardiovascular system, the prevalence of coronary heart disease in women is very low before the age of 50, increases rapidly after the age of 55, reaches a peak around the age of 65, and lasts for about 10 years. Therefore, most cases of acute myocardial infarction in women occur in people over 55 years old, accounting for more than 80% of the total number of female patients.

2. Coexistence of multiple cardiovascular diseases makes treatment difficult. Women have more risk factors for acute myocardial infarction, such as obesity, lack of exercise, high salt intake, strenuous activities, and mood swings. In addition, the incidence of acute myocardial infarction in women is often closely related to the existence of multiple cardiovascular diseases, such as hypertension, hyperlipidemia, diabetes, etc., which form a vicious circle, aggravate the condition and increase the difficulty of treatment.

3. Atypical clinical manifestations and easy misdiagnosis are one of the characteristics of acute myocardial infarction in women. Generally speaking, the early symptoms of acute myocardial infarction in women are mostly non-specific symptoms such as chest tightness, palpitations, headache, dizziness, back pain, difficulty breathing or upper abdominal fullness, or sudden syncope, impaired consciousness and arrhythmia, but often lack typical symptoms such as severe chest pain, nausea, vomiting and radiating pain. Therefore, acute myocardial infarction in women is easily misdiagnosed.

4. The disease progresses rapidly and the mortality rate is high. Because acute myocardial infarction in women is complicated and progresses rapidly, they are prone to serious complications such as shock, heart failure, and arrhythmia in the early stages, resulting in a relatively higher mortality rate. Data show that the mortality rate of acute myocardial infarction in women aged 55-75 can reach 38%, more than twice that of acute myocardial infarction in men.
