While a myocardial infarction (heart attack) can happen to anybody, regardless of race, gender, or age, there are many factors that can increase a person’s risk of developing a MI. Research has shown that one of these factors is actually pregnancy. During pregnancy, the normal cardiac changes such as hypercoagulation and risk factors such as hypertension can increase a woman’s risk of developing an AMI. Even though AMIs are rare in women of reproductive age, pregnancy increases the risk by approximately 3-4 times. Pre-existing heart conditions and complications during pregnancy increase this risk even further .
Other risk factors :
- Age above 35 years old
- Diabetes mellitus
- Thrombophilia (increased ability of blood to clot)
- African race
- If an AMI does occur during or after pregnancy, it poses a very high risk for the mother. Mortality rates range from 5.1-11%. Therefore, it is important for clinicians to recognize abnormal symptoms. If a woman has chest pain or shortness of breath, an AMI is a possibility. Other potential diagnoses are pulmonary embolism and aortic dissection. An ECG and troponin levels are important methods to diagnose the issue .
Signs & Symptoms :
Signs and symptoms of a heart attack are not always obvious in women, and can be even less obvious during pregnancy. Here are some important ones to look out for:
- Pressure, pain or squeezing in the center of chest
- Pain the arms, back, neck, jaw or stomach.
- Shortness of breath
- Cold sweat or chills,
If any of these symptoms are present, it is important to call 911 immediately to get to a hospital. Even if it is not a heart attack, it is better to be safe than sorry.
