Coronary Dissection

Ischemic Complications of Pregnancy: Who is at Risk?

Pregnancy is a physiologic challenge, with significant hormonal, metabolic, and hemodynamic changes. Cardiac output is objectively increased by the fifth week after the last menstrual period and continues to grow by approximately 45 % by 24 weeks in the normal, singleton pregnancy. This is facilitated by elevations in heart rate and stroke volume and a decrease in systemic vascular resistance.

Spontaneous Coronary Artery Dissection Presenting with Stroke

Spontaneous coronary artery dissection (SCAD) is a rare and potentially life-threatening condition that can cause rapid deterioration and fatal myocardial infarction. By definition, SCAD implies formation of a false lumen around the true lumen of the artery, which may or may not communicate with the true lumen. By compression of the true lumen, this may cause a blockage of the coronary flow, resulting in myocardial infarction (MI). Early recognition is important as the dissection can progress unpredictably upstream or downstream.
