Covid-19: Scotland failed to apply measures identified in pre-pandemic exercises, says report

OBJECTIVE In the chronic phase of myocardial infarction, relation between recovery and infarct related artery status remains unclear. The spontaneous changes in rest-redistribution thallium defect size were prospectively studied over six months 52 patients with Q wave infarction. DESIGN Changes rest size, uptake area, radionuclide left ventricular ejection fraction compared to quantitative coronary angiogram data. Two groups considered: a percentage stenosis below 100% (group 1, n = 31); an occluded 2, 21). RESULTS overall population, mean (SD) decreased from 28.2 (17.2)% 24.9 (19.3)% whole myocardium (p 0.01), while, this increased 62.9 (13.7)% 66.9 (15.6)% < 0.001). At time inclusion, uptake, similar both groups. group 1 only, reduction correlated improvement (r 0.41, p 0.02) was stenosis. TIMI 3 reduced while other (−5.1 (7.0)% v +11.0 (14.4)%, contrast, no significant relations found 2 patients. CONCLUSION Late can occur patent artery, depending on flow grade low is associated functional improvement.
