Non-ST elevation myocardial infarction in pregnancy-a critical review of current evidence and guidelines.

Treatment for acute coronary syndrome (ACS) in women during pregnancy is challenging. Current standard treatment for ACS includes coronary angioplasty with guideline-directed medical therapy including aspirin, P2Y12 inhibitors, beta-blockers, angiotensin converting enzyme inhibitors, which may portend adverse effects to the fetus. ACS increases ischemic and obstetric complications during pregnancy and the postpartum period.

High-Risk "Protected" Percutaneous Coronary Intervention with Mechanical Circulatory Support in a Non-Surgical Center - An Early Asian Experience.

High-risk "protected" percutaneous coronary intervention (PCI) using mechanical circulatory support (MCS) devices, particularly the Impella axial pump, has emerged as a viable treatment option for high-risk patients with satisfactory clinical outcomes. High-risk and complex interventions have mostly remained within the domain of surgical centers. We report on an early "protected" PCI experience using MCS with the Impella flow pump at a high-volume PCI hospital without on-site surgery.

A case report of dipyridamole stress-induced ST depression progressing to ST-elevation myocardial infarction despite intravenous aminophylline: steal, spasm, or something else?

Background: Dipyridamole stress is commonly used for myocardial perfusion imaging and is generally safe. Myocardial ischaemia can occasionally occur and is classically thought to be due to coronary steal as a result of redistribution of flow away from collateral dependent myocardium. Although ischaemia more commonly presents as electrocardiographic (ECG) ST depression and angina, ST-elevation myocardial infarction may occur as a very rare complication.
