Prevalence and predictors of long corrected QT interval in HIV-positive patients: a multicenter study.

Aims: HIV and highly active antiretroviral therapy (HAART) may affect cardiac conduction, and a higher incidence of sudden death has been recognized in HIV-positive patients. Nevertheless, predictors of prolonged corrected QT interval (cQT) have been poorly described. The aim of the study was to investigate the prevalence and predictors of long cQT in a cohort of HIV-positive patients.

Impact on prognosis of periprocedural myocardial infarction after percutaneous coronary intervention.

Introduction: Different definitions of periprocedural myocardial infarction (MI) after percutaneous coronary intervention (PCI) have been provided, but their impact on prognosis remains to be determined.

Methods: Procedural data from consecutive patients undergoing PCI from 2009 to 2011 were revised to adjudicate diagnosis of periprocedural MI according to CK-MB increase (>3 × URL and >5 × URL), to troponin increase (>3 × 99th percentile URL and >5 × 99th percentile URL) and to recent 2012 Task Force and Society for Cardiovascular Angiography and Interventions (SCAI) definitions. Major adverse cardiovascular events (MACE) was the primary end-point.

Thirty-day readmission rates after PCI in a metropolitan center in Europe: incidence and impact on prognosis.

Introduction: Thirty-day readmission rates after percutaneous coronary intervention (PCI) have been related to adverse prognosis, and represent one of the most investigated indicators of quality of care. These data, however, derive from non-European centers evaluating all-cause readmissions, without stratification for diagnosis.

Methods: All consecutive patients undergoing PCI at our center from January 2009 to December 2011 were enrolled.

Heart failure in patients with human immunodeficiency virus: a review of the literature.

Coronary artery disease represents the leading cause of death for HIV patients treated with highly active antiretroviral treatment. Besides this, an extensive amount of data related to the risk of overt heart failure and consequently of atrial fibrillation and sudden cardiac death (SCD) in this population has been reported. It seems that persistent deregulation of immunity in HIV-infected patients is a common pathway related to both of these adverse clinical outcomes.
