What Causes MINOCA?
A systematic imaging protocol of coronary angiography, optical coherence tomography, and cardiac MRI in women clinically diagnosed with myocardial infarction with non-obstructive coronary artery disease revealed a cause in 84%, with three-quarters exhibiting an ischemic etiology.

Ticagrelor in the Elderly: More Potent Platelet Inhibition Not Always Better
In a study of 14,000 elderly patients with acute myocardial infarction, treatment with ticagrelor was associated with higher risks of bleeding and all-cause death vs. clopidogrel.

Which Acute Myocardial Infarction Patients Need a Blood Transfusion?
A randomized trial of a restrictive blood transfusion strategy vs. a more liberal strategy in patients with acute myocardial infarction and anemia showed the restrictive strategy is noninferior to the liberal strategy for preventing the primary outcome of death, reinfarction, stroke, or emergency revascularization.

Does BAMI Spell the End for Cell-Based Therapy After Acute Myocardial Infarction?
Investigators tested the mortality benefit of intracoronary bone marrow cells in patients with successfully reperfused acute myocardial infarction. They observed no effect on mortality.

Management of Cardiac Arrest Patients Without STEMI
Since there were no significant differences in outcomes at 90 days or one year, coronary interventions in successfully resuscitated cardiac arrest patients without evidence of STEMI or cardiogenic shock can be delayed until neurologic recovery is evident.

Paper: Acute Coronary Syndrome Patients are Malnourished
Nutritional interventions may be valuable for this population.

Thin Evidence Supporting the Obesity Paradox in STEMI
This largest-to-date analysis of six randomized studies of ST-elevation myocardial infarction revealed no association between body mass index and infarct size, one-year mortality, or heart failure hospitalization.

Discrimination, Disparities, and Dangerous Cardiovascular Outcomes
A pair of papers underscore the persistent inequities that negatively affect the health of people of color, especially African Americans.

Two Possible Mechanisms of Disease in COVID-19
COVID-19 infection may be associated with an increased risk of blood clotting and related thrombotic events, but there are insufficient data to support indiscriminately discontinuing medications that play a critical role in the management of chronic cardiovascular disease.

Is Exercise ECG Testing Dead?
A post-hoc analysis of the SCOT-HEART trial demonstrated exercise ECG is predictive of future coronary heart disease events and mortality. However, coronary CT angiography is more accurate for the detection of coronary artery disease and is more strongly associated with future coronary events.
