As part of a community-based study of patients hospitalized with acute myocardial infarction (AMI) in the Worcester, Massachusetts, metropolitan area, changes over time in the incidence rates of complete heart block (CHB) complicating AMI, and the prognostic impact of CHB on the in-hospital and long-term survival of these patients were examined. In all, 4,762 patients with validated AMI hospitalized at 16 hospitals in the Worcester metropolitan area during 1975, 1978, 1981, 1984, 1986 and 1988 constituted the study sample. The incidence rates of CHB complicating AMI remained relatively stable at 5.8% over the 13-year (1975 to 1988) period studied. The …

Limited contemporary data are available describing the incidence rates, hospital prognosis, and factors associated with the occurrence of ventricular fibrillation (VF) in patients hospitalized with acute myocardial infarction (AMI). The objectives of our study were to examine 3-decade-long trends (1975 to 2005) in the magnitude, predictors, and hospital case-fatality rates associated with VF in residents of a large New England metropolitan area hospitalized at all area medical centers with an uncomplicated AMI. The study population consisted of 7,472 residents of the Worcester (Massachusetts) metropolitan area hospitalized with an uncomplicated AMI in 15 annual periods from 1975 to 2005. The overall …
Temporal Trends (1975 Through 1990) In The Incidence And Case-Fatality Rates Of Primary Ventricular Fibrillation Complicating Acute Myocardial Infarction. A Communitywide Perspective, David Chiriboga, Jorge Yarzebski, Robert Goldberg, Joel Gore, Joseph Alpert

BACKGROUND: As part of a population-based study of acute myocardial infarction, we examined changes over time in the incidence and in-hospital case-fatality rates of primary ventricular fibrillation complicating acute myocardial infarction. METHODS AND RESULTS: Patients with validated acute myocardial infarction hospitalized at 16 hospitals in the Worcester, Mass, metropolitan area between 1975 and 1990 comprised the study sample. During the 15-year study period, 5.1% of patients developed primary ventricular fibrillation in the setting of uncomplicated acute myocardial infarction, with this rate remaining relatively constant over time. Both age- and multivariable-adjusted analyses showed no significant trend in the incidence rates of …

Atrial fibrillation (AF) is a common complication of acute myocardial infarction (AMI) and this arrhythmia is associated with increased morbidity and mortality in patients with AMI. Limited information is available, however, about changing, and contemporary, trends in the incidence and death rates associated with AF complicating AMI. We examined the magnitude and impact of AF and the risk of stroke and hospital and long-term death rates in a population-based study of patients hospitalized with AMI. The study population consisted of 7,513 residents of the Worcester, Massachusetts, metropolitan area hospitalized with AMI at all greater Worcester medical centers during 9 biennial …
Changes Over Time In The Incidence And Case-Fatality Rates Of Primary Ventricular Fibrillation Complicating Acute Myocardial Infarction: Perspectives From The Worcester Heart Attack Study, Craig Thompson, Jorge Yarzebski, Robert Goldberg, Darleen Lessard, Joel Gore, James Dalen

BACKGROUND: Limited population-based data are available that describe temporal and recent trends in the incidence and case-fatality rates in patients with primary ventricular fibrillation (VF) complicating acute myocardial infarction (AMI). The purpose of this study was to describe changes over a 22-year period (1975 through 1997) in the incidence and hospital case-fatality rates of primary VF complicating AMI from a multihospital, community-wide perspective. METHODS AND RESULTS: This was an observational study of metropolitan Worcester residents hospitalized with a validated uncomplicated AMI (n = 5020) in all hospitals in the Worcester, Massachusetts, metropolitan area (1990 census population = 437,000) during 11 …
Twenty-Two Year (1975 To 1997) Trends In The Incidence, In-Hospital And Long-Term Case Fatality Rates From Initial Q-Wave And Non-Q-Wave Myocardial Infarction: A Multi-Hospital, Community-Wide Perspective, Mark Furman, Harold Dauerman, Robert Goldberg, Jorge Yarzebski, Darleen Lessard, Joel Gore

OBJECTIVES: The goal of this study was to examine long-term trends in the incidence, in-hospital and long-term mortality patterns in patients with an initial non-Q-wave myocardial infarction (NQWMI) as compared with those with an initial Q-wave myocardial infarction (QWMI). BACKGROUND: Limited data are available describing trends in the incidence and mortality from an initial QWMI and NQWMI from a multi-hospital community-wide perspective. METHODS: Our study was an observational study of 5,832 metropolitan Worcester, Massachusetts residents (1990 census = 437,000) hospitalized with validated initial acute MI in all greater Worcester hospitals during 11 annual periods between 1975 and 1997. RESULTS: The …

An elevated white blood cell (WBC) count at the time of hospital presentation is associated with increased mortality after acute myocardial infarction (AMI). The association between WBC count and the development of clinically significant complications of AMI and death during hospitalization for AMI is, however, less clear. The objectives of this observational study were to examine the association between baseline WBC count, the development of heart failure, cardiogenic shock, and death during hospitalization for AMI from a more generalizable community-wide perspective. The study sample consisted of adult residents of all ages from the Worcester, Massachusetts, metropolitan area (1990 census estimate …
