Studies show that 30% of NonSTEMI have an occluded infarct artery at the time of angiography done 24 hours after presentation. These patients have worse outcomes: higher mortality, more CHF, higher biomarkers, and worse ejection fractions than the NonSTEMI patients with open arteries. This is because of subtle ECG findings.

Immediate and early percutaneous coronary intervention in very high-risk and high-risk non-ST segment elevation myocardial infarction patients. Her long term outcome (with very large LAD MI and EF of 30%) is unknown. Otherwise it results in a terrible outcome, as in this case, with devastating permanent loss of myocardium).

Background Drug-eluting stents (DESs) have become the gold standard of coronary angioplasty since their inception in 2002. We aimed to compare outcomes between a broad range of second-generation DP-DES and BP-DES in an all-comer population. Conclusion Clinical follow-up up to 2 years shows similar outcomes between BP-DES and DP-DES.

Soviet biologist Trofim Lysenko famously rejected the objective reality of Mendelian genetics because it clashed with the Marxist philosophy that the environment, not genetics, was the primary determinant of outcomes. But what should matter is outcomes not diagnoses. Physician assessments often misclassify chest pain as nonanginal.

When one of these arteries becomes completely blocked by a blood clot, it results in a heart attack, also known as MI (Myocardial infarction). When a person experiences a heart attack or myocardial infarction, they may feel chest pain and other symptoms in different parts of their body.

A combination of balloon angioplasty, stent implantation, and intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) was employed, resulting in significant thrombus reduction and improved coronary flow.
