What is the leading cause of cardiovascular disease during pregnancy?

The leading cause of cardiovascular disease during pregnancy is often attributed to hypertension. Hypertension can manifest as gestational hypertension or preeclampsia, both of which pose significant risks to both the mother and the fetus. These conditions can lead to severe complications, such as placental abruption, preterm birth, and maternal organ failure.

Rheumatic heart disease, while it is a serious condition that can affect women's health during pregnancy and can lead to complications, is not as prevalent or common as hypertension. Diabetes, though it can also lead to cardiovascular complications, is not specifically the leading cause during pregnancy. Obesity is another significant risk factor that contributes to various health issues in pregnancy, including hypertension and diabetes, but it does not specifically categorize as the leading cause of cardiovascular disease.

Understanding the implications of hypertension during pregnancy is crucial as it requires careful monitoring and management to ensure the health and safety of both the mother and the developing fetus.
