Effects of Intracoronary Alteplase on Microvascular Function in Acute Myocardial Infarction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Impaired microcirculatory reperfusion worsens prognosis following acute ST‐segment–elevation myocardial infarction. In the T‐TIME (A Trial of Low‐Dose Adjunctive Alteplase During Primary PCI) trial, microvascular obstruction on cardiovascular ...

What is the Role of Coronary Physiology in the Management of Patients with Chronic Coronary Syndromes?

Reviews in Cardiovascular Medicine, 2022
The use of coronary physiology in patients with chronic coronary syndromes is highly variable, and the evidence base complex. Tests of coronary physiology have traditionally been invasive (e.g., fractional flow reserve), but novel non-invasive methods ...
