Impact of Chronic Kidney Disease on the Coronary Revascularization Guided by Intracoronary Physiology: Results of the First Registry with Long-Term Follow-Up in a Latin American Population.

The use of invasive physiology methods in patients with renal dysfunction is not well elucidated. Our objective was to evaluate the in-hospital and long-term results of using intracoronary physiology to guide revascularization in patients with chronic kidney disease. In this retrospective study, we evaluated 151 patients from January 2018 to January 2022, divided into 2 groups: CKD (81 patients [114 lesions]) and non-CKD (70 patients [117 lesions]).

Impact of Sex Differences on the Outcomes of Coronary Invasive Physiological Assessment: Long-Term Follow-Up in a Brazilian Population.

Objective: This study aimed to evaluate the rate of major adverse cardiac events (MACEs; the sum of death, myocardial infarction, and revascularization rates) according to interventional strategies guided by invasive physiological methods in both sexes in a Brazilian population during long-term follow-up for an average of 2 years.

Methods: This retrospective single-center study included 151 consecutive patients (232 lesions) between January 2018 and January 2022. The participants were divided into two groups: the female group (FG), comprising 59 patients with 88 lesions, and the male group (MG), comprising 92 patients with 144 lesions.

Acute Coronary Syndrome with Non-Obstructive Plaque on Angiography and Features of Vulnerable Plaque on Intracoronary Optical Coherence Tomography.

Optical coherence tomography (OCT) has a high spatial resolution and is useful in identifying coronary lesions with high-risk features (vulnerable plaques). These plaques are strongly associated with acute coronary syndrome (ACS). In this report, we present the case of a 43-year-old male patient presenting with typical chest pain that began three hours prior to admission.

Extensive right coronary artery thrombosis in a patient with COVID-19: A case report.

Background: Occurring in approximately 30% of hospitalized patients, cardiovascular complications that take place during the course of coronavirus disease 2019 (COVID-19) have been shown to cause morbidity and mortality. This case is the first report of extensive right coronary artery (RCA) thrombosis that was evaluated by intracoronary imaging and intracoronary invasive physiology in a patient with COVID-19.

Case Summary: A 62-year-old woman presented with flu-like symptoms; ten days later, she presented with inferior ST-segment elevations, chest pain, dyspnea, nausea and vomiting.
