Comparison of Outcomes of Balloon Aortic Valvuloplasty Plus Percutaneous Coronary Intervention Versus Percutaneous Aortic Balloon Valvuloplasty Alone During the Same Hospitalization in the United States
The use of percutaneous aortic balloon balvotomy (PABV) in high surgical risk patients has resurged because of development of less invasive endovascular therapies. We compared outcomes of concomitant PABV and percutaneous coronary intervention (PCI) with PABV alone during same hospitalization using nation's largest hospitalization database. We identified patients and determined time trends using the International Classification of Diseases, Ninth Revision, Clinical Modification, procedure code for valvulotomy from Nationwide Inpatient Sample database 1998 to 2010.ST-T Wave Abnormality in Lead aVR and Reclassification of Cardiovascular Risk (from the National Health and Nutrition Examination Survey-III)
Electrocardiographic lead aVR is often ignored in clinical practice. The aim of this study was to investigate whether ST-T wave amplitude in lead aVR predicts cardiovascular (CV) mortality and if this variable adds value to a traditional risk prediction model. A total of 7,928 participants enrolled in the National Health and Nutrition Examination Survey (NHANES) III with electrocardiographic data available were included. Each participant had 13.5 ± 3.8 years of follow-up. The study sample was stratified according to ST-segment amplitude and T-wave amplitude in lead aVR.
