Clinical Trial
Association between atmospheric conditions and occurrence of out-of-hospital cardiac arrest- 10-year population-based survey in Osaka.
Weather conditions affect the occurrence of cardiovascular disease. The aim of this study was to investigate the associations between atmospheric conditions including temperature, pressure, and humidity, and the occurrence of out-of-hospital cardiac arrests (OHCAs) with cardiac etiology. ⋯ The occurrence of adult OHCA with cardiac etiology increases with decreasing temperature of the day. Elderly people are more susceptible to severe weather conditions.

Chronic ischemic mitral regurgitation (IMR) is still a significant clinical problem. It is present in 10-20% of patients with coronary artery disease and is associated with a worse prognosis after myocardial infarction and subsequent revascularization. ⋯ In order to do so, the condition will be defined and the evolution of classic or traditional surgical approaches to repairing or replacing the mitral valve in the setting of IMR will be described. Finally, novel approaches to the repair of the ischemic mitral valve will be considered.

Interest in hormonal response after pediatric cardiac surgery is growing, but many aspects remain unclear. The aim of this study was to test age-related variations and prognostic values of thyroid hormones, and brain natriuretic peptide (BNP) levels before and after surgery. ⋯ BNP and thyroid response after pediatric cardiac surgery differs widely according to age. Beside Aristotle score, combined measurement of fT3 and TSH are the strongest predictors of TTE, especially in neonates.

Pericardial effusion (PE) may complicate permanent heart rhythm device (HRD: pacemaker, implantable cardioverter-defibrillator, and cardiac resynchronization therapy) placement. Incidence of and risk factors for this complication have never been prospectively evaluated. ⋯ PE is frequently seen after HRD implantation, but rarely requires any therapy. Female gender and antiplatelet therapy are risk factors, whereas previous cardiac surgery was a protective factor.

Recent studies have proven that initial renal dysfunction and worsening renal function during hospitalization can predict the clinical outcome of patients with acute myocardial infarction (AMI). There is limited study regarding acute kidney injury (AKI) by the RIFLE classification (Risk of renal failure, Injury to the kidney, Failure of kidney function, Loss of kidney function, and End-stage renal failure) to assess the outcome of AMI survivors. ⋯ Independent of initial renal dysfunction on admission, the AKI severity by RIFLE classification may be useful in establishing the hospital discharge risk score for predicting long-term mortality in AMI patients who survive to discharge.
