Most studies of an association of visit-to-visit variability of blood pressure with increased risk of future adverse cardiovascular events are of short duration and rarely include a placebo group. Using data from the double-blind, placebo-controlled Systolic Hypertension in the Elderly Program, the authors examined mortality from cardiovascular causes up to(More)
BACKGROUND We assessed trends in the prognosis of patients with acute myocardial infarction hospitalized in New Jersey hospitals. In recent decades, in-hospital mortality has declined markedly but the decline in longer-term mortality is less pronounced, implying that mortality after discharge has worsened. METHODS AND RESULTS Using the Myocardial(More)
The case is reported of a patient who underwent aortic valve replacement (AVR) in 1969 and received a (first-generation) Björk-Shiley Delrin valve. Forty years later, the patient presented to the authors' hospital in congestive heart failure and with echocardiographic evidence of severe stenosis and mild aortic regurgitation. The patient underwent a redo(More)
BACKGROUND The incidence rates of ischemic stroke and ST-segment elevation myocardial infarction (STEMI) have decreased significantly in the United States since 1950. However, there is evidence of flattening of this trend or increasing rates for stroke in patients younger than 50 years. The objective of this study was to examine the changes in incidence(More)
BACKGROUND To assess the adverse clinical effects of left anterior hemiblock alone or in combination with right bundle branch block and of complete left bundle branch block in comparison with isolated right bundle branch block and the relationship of these effects with altered mechanoelectric factors resulting in left ventricular dysfunction. METHODS In a(More)
His bundle electrograms were recorded in 2 adult cases of congenital corrected transposition of the great arteries. Both patients had prolonged HV conduction and a His potential that was wide. These findings are different from those reported in congenital atrioventricular block without ventricular inversion wherein an abnormality within the AHperiod has(More)
In two cases of permanent transvenous pacemaker failure, the defective pacing electrode could not be removed. A second pacing electrode was placed in the same vein to avoid an additional operation. To our knowledge, this simple and effective procedure has not been previously reported.
OBJECTIVE To assess the relationship between preeclampsia or eclampsia and stroke, myocardial infarction (MI), subsequent cardiovascular outcomes, and long-term survival. METHODS Using the Myocardial Infarction Data Acquisition System in New Jersey (1994-2009), we analyzed cardiovascular outcomes in women with and without preeclampsia or eclampsia and a(More)
