Recent Trends In The Incidence Rates Of And Death Rates From Atrial Fibrillation Complicating Initial Acute Myocardial Infarction: A Community-Wide Perspective, Robert Goldberg, Jorge Yarzebski, Darleen Lessard, Jacqueline Wu, Joel Gore

Jorge L. Yarzebski

BACKGROUND: Limited information is available about recent trends in the incidence and death rates from atrial fibrillation (AF) complicating acute myocardial infarction (AMI). The purpose of this study was to examine the impact and trends over time of AF complicating initial AMI. METHODS: We conducted a longitudinal study of 2596 residents of the Worcester, Massachusetts, metropolitan area with initial AMI and without previous AF who were hospitalized at all area hospitals in 5 annual periods between 1990 and 1997. RESULTS: A total of 13% of hospitalized patients developed AF. There was a marked decrease in the proportion of patients who …

Use Of Do-Not-Resuscitate Orders In Patients With Kidney Disease Hospitalized With Acute Myocardial Infarction, Joline Chen, Jonathan Sosnov, Darleen Lessard, Jorge Yarzebski, Joel Gore, Robert Goldberg

BACKGROUND: Patients with kidney disease are at increased risk for adverse health outcomes in comparison to patients without kidney disease. Therefore, patients with kidney disease may have greater use of do-not-resuscitate (DNR) orders than patients without kidney disease in the setting of an acute illness. We examined the association between advanced kidney disease and use of DNR orders in patients admitted with an acute myocardial infarction (AMI) to all greater Worcester, MA, hospitals as part of an epidemiological study.

METHODS: Use of DNR orders in 4,033 Worcester residents hospitalized with AMI at 11 greater Worcester medical centers during 1997, 1999, …

Treatment Practices And Outcomes Of Patients With Established Peripheral Arterial Disease Hospitalized With Acute Myocardial Infarction In A Community Setting, Frederick Spencer, Darleen Lessard, Chyke Doubeni, Jorge Yarzebski, Joel Gore, Robert Goldberg

BACKGROUND: There are little contemporary data available describing the hospital and long-term outcomes of patients with peripheral arterial disease (PAD) who are hospitalized with acute myocardial infarction (AMI). The objectives of our population-based study were to examine the hospital and long-term outcomes, as well as the use of different treatment practices, among patients with established PAD who were hospitalized with AMI. METHODS: The study sample consisted of 4480 patients hospitalized with AMI at all Worcester, Mass, medical centers in 4 alternate years between 1997 and 2003. RESULTS: Among the metropolitan Worcester residents hospitalized with AMI, 13.5% had a history of …


Trends (1986 To 1999) In The Incidence And Outcomes Of In-Hospital Stroke Complicating Acute Myocardial Infarction (The Worcester Heart Attack Study), Frederick Spencer, Joel Gore, Jorge Yarzebski, Darleen Lessard, Elizabeth Jackson, Robert Goldberg Jul 2010

Trends (1986 To 1999) In The Incidence And Outcomes Of In-Hospital Stroke Complicating Acute Myocardial Infarction (The Worcester Heart Attack Study), Frederick Spencer, Joel Gore, Jorge Yarzebski, Darleen Lessard, Elizabeth Jackson, Robert Goldberg

Although stroke is an infrequent hospital complication of acute myocardial infarction (AMI), limited contemporary data are available about the incidence and death rates associated with this serious complication. The objective of this population-based study was to examine temporal trends (1986 to 1999) in the risk of stroke and associated hospital outcomes in patients hospitalized with AMI. This was an observational study of 6,325 metropolitan Worcester, Massachusetts, residents hospitalized with validated AMI and without prior stroke at all greater Worcester hospitals during 8 one-year periods between 1986 and 1999. Overall, 1.5% of patients (n = 92) with confirmed AMI developed an …
