Acute and Chronic Effects of COVID-19 on the Cardiovascular System.

COVID-19 has shown significant morbidity with the involvement of multiple systems, including the cardiovascular system. Cardiovascular manifestations in the acute phase can include myocardial injury itself, myocardial infarction, venous thromboembolic events, myocarditis, Takotsubo syndrome, and different arrhythmic events. Myocardial injury defined by the rise of cardiac biomarkers in blood has been found in multiple studies with a prevalence of about 20%.

Impact of Chronic Kidney Disease in Chronic Total Occlusion Management and Clinical Outcomes.

Background: Data on the impact of chronic kidney disease (CKD) on clinical outcomes in chronic total occlusion (CTO) patients is scarce, and the optimal treatment strategy for this population is not well established. This study aims to compare differences in CTO management and long-term clinical outcomes, including all-cause and cardiac mortalities, according to baseline glomerular filtration rate (GFR).

Methods: All patients with at least one CTO diagnosed in our center between 2010 and 2014 were included.
