Abstract Background Primary percutaneous coronary intervention is considered the “gold standard” for coronary reperfusion. However, when not available, the drug-invasive strategy is an alternative method and the electrocardiogram (ECG) has been used to identify reperfusion success. Objectives Our study aimed to assess ST-Segment changes in post-thrombolysis and their power to predict recanalization and using the angiographic scores TIMI-flow and Myocardial Blush Grade (MBG) as an ideal reperfusion criterion. Methods 2,215 patients with ST-Segment Elevation Myocardial Infarction (STEMI) undergoing fibrinolysis [(Tenecteplase)-TNK] […]

Abstract Background: The beneficial effects of Elabela on the cardiovascular system have been shown in studies. Objective: To compare serum Elabela levels of chronic total occlusion (CTO) patients with control patients with normal coronary arteries, and to investigate whether there is a correlation with collateral development. Methods: The study was planned cross-sectionally and prospectively. Fifty patients (28.0% female, mean age 61.6±7.3years) with CTO in at least one coronary vessel and 50 patients (38% female, mean age 60,7±6.38 years) with normal […]

Abstract Background: Coronary slow-flow phenomenon (CSFP) and coronary no-reflow phenomenon (CNP) are associated with increased risk of major cardiovascular adverse events (MACE). Objectives: This study aimed to evaluate and compare the one-year clinical follow-up outcomes among patients with CNP and CSFP who underwent percutaneous coronary interventions (PCI) in non-ST elevation myocardial infarction (NSTEMI). Methods: This study included a total of 858 patients who were diagnosed with NSTEMI and underwent PCI within 24 h of symptom onset. The patients were divided […]

Wellens Syndrome, also known as “Anterior Descending Coronary T-wave syndrome”, was described in 1982 by Dr. Henrick Joan Joost (Hein) Wellens, a Dutch physician who also contributed to the characterization of the reentry mechanism in Wolff–Parkinson–White syndrome (WPWS). Originally described during hospital admission (60% at admission and 40% at the follow-up) of patients with unstable angina, it was characterized by the occurrence of 2 electrocardiographic patterns, with pattern A in 25% of patients and B in 75% of patients. […]

Abstract Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis (AS) in patients with elevated surgical risk. Concomitant coronary artery disease affects 55-70% of patients with severe AS. Percutaneous coronary intervention in patients with TAVI can be challenging. We report a case of acute coronary obstruction immediately following transapical TAVI deployment requiring emergent rotational atherectomy.

A 69-year-old male with hypertension, dyslipemia and no previous cardiovascular disease presented a transient ST-segment elevation on electrographic (ECG) monitoring during a planned ureteroscopy. The patient remained asymptomatic during the postoperative period. He only referred very sporadic episodes of effort chest pain in the last years without progression or events at rest. Given the lack of ECG registry, an exercise stress echocardiogram was indicated. The study was clinical and echocardiographically positive for inducible ischemia, with hypokinesia of the mid and […]
