The present retrospective cohort study aimed to investigate the long-term outcomes of successful recanalization vs. Of these, 1, patients A propensity score matching PSM was conducted to reduce the impact coronary collaterals potential confounding on the outcomes. The primary outcome was the frequency of major adverse cardiac events MACEs. Results: Throughout a 2.

There coronary collaterals no significant difference in MACE collatsrals The primary outcome among patients with impaired and preserved LV systolic function after PSM was similar to that from earlier findings before PSM was conducted. The presence of a CTO was found to be the strongest independent predictor of incomplete revascularization in patients with complex coronary artery disease CAD undergoing percutaneous coronary interventions PCIs.

Some observational studies have reported that CTO-PCI is associated with angina symptom relief, and that it improves long-term survival and left ventricular ejection fraction LVEF 4 — 7. However, CTO-PCI is performed infrequently, due to lesional complexity, procedural complications, and coronary collaterals findings, and nearly half of CTO patients are managed by conservative medical therapy MT 18 — The number of patients with LV systolic dysfunction is significant.

However, the clinical outcomes of impaired and preserved LV systolic function in CTO patients have been rarely reported, and there are no current guidelines or consensus related to the optimal treatment strategy for CTO lesions in patients with LV systolic dysfunction. Accordingly, we aimed coronary collaterals assess the long-term outcomes of optimal MT vs.

Materials and Coronary collaterals Study Design and Population A total of 27, coronary angiography procedures were performed at our center in the period between January and December Patients with a confirmed CTO diagnosis were selected.


Exclusion criteria were as follows: history of coronary artery bypass grafting CABGbecause CTO lesions in patients with history of CABG surgery show more extensive calcification, negative remodeling, and accelerated progression of atherosclerosis, which are associated with lower success rates, higher rates of complications, and worse outcomes 13 ; CABG or failed CTO-PCI; acute myocardial infarction MI ; cardiogenic shock; and cancer. A total of 1, patients were enrolled in the study. Coronary collaterals were assigned to revascularization or optimal MT groups according to the initial treatment strategy. Decisions for patients coronary collaterals for revascularization were based on at least one of the following conditions: 1 presence of symptomatic angina, 2 inducible myocardial ischemia salva jennifer coronary collaterals echocardiography or myocardial perfusion scan, and 3 myocardial viability on cardiac magnetic resonance imaging MT was strongly preferred colaterals asymptomatic patients who did not have available viability data or in subjects with proven absence of viability.

PCI was preferred in symptomatic patients even without collatwrals on viability or in asymptomatic patients with viability. The decision to perform PCI for CTO patients was also dependent on several factors, including co-morbidity, the extent of other coronary artery disease, CTO location, technical difficulty, and doctors' and patients' preference 14 Patients' LV systolic function was evaluated using a two-dimensional echocardiogram.]
