Twenty-Year Trends In The Incidence Of Stroke Complicating Acute Myocardial Infarction: Worcester Heart Attack Study., Jane Saczynski, Frederick Spencer, Joel Gore, Jerry Gurwitz, Jorge Yarzebski, Darleen Lessard, Robert Goldberg

Jorge L. Yarzebski

BACKGROUND: Given the improved survival of patients after acute myocardial infarction (AMI), more patients are at risk for cerebrovascular complications of AMI. Trends in the magnitude of stroke in the setting of AMI are not well characterized, however, and neither have contemporary trends in the hospital death rates of patients developing acute stroke been examined. RESULTS: Of 9220 patients without a history of stroke hospitalized with confirmed AMI between 1986 and 2005 in all greater Worcester medical centers, 132 (1.4%) experienced an acute stroke during hospitalization. The proportion of patients with AMI who developed a stroke increased through the 1980s …

BACKGROUND: Stroke is the third leading cause of death in Puerto Rico. We examined the pre-hospital phase, management and case-fatality-rates (CFR) of patients discharged with acute stroke from the Carolina University of Puerto Rico Hospital during 2007.

METHODS: Trained personnel collected information on demographics, delay-time, mode-of-transportation, management, and mortality from all medical records. STATAa was utilized to conduct univariate comparison of demographics, mode-of-transportation, therapeutics and diagnostic characteristics. Logistic regression analysis assessed cohort effect and controlled for confounders.

RESULTS: The average age was 69.1 years, and 53% were males. The average delay between onset of symptoms suggestive of stroke and arrival …

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 …
