Acute Coronary Syndrome in Pre- and Post-partum Women - A Review.

Acute coronary syndrome (ACS) during pregnancy and the post-partum period are weighed by a high mortality rate for the mother and foetus. They should be considered as multifactorial diseases with a special role for sexual hormones. In this setting, ACS is mostly related to an early atherosclerotic disease, even if other conditions are responsible. Indeed, an important part is due to spontaneous coronary artery dissection, more common during delivery and the post-partum period. In the remaining situation, an isolated intracoronary thrombus or a normal angiographic pattern can be found at angiography. Pathophysiology is still uncertain with different hypothetical mechanisms. Prompt diagnosis of ACS and aetiology are essential for an optimal therapeutic strategy. Difficulties in treatment management is a matter for debate, especially in pre-partum women. In the last two decades improvements of diagnostic tools, coronary angiography and subsequent percutaneous treatment have changed the natural history of this rare condition.
