In a large population of patients (n = 3666) who were discharged from the hospital after acute myocardial infarction and followed up for 1 year, factors associated with recurrent nonfatal (n = 171) or fatal (n = 74) infarction were identified. Also, the effects of combining various end points (recurrent nonfatal or fatal infarction and other cardiac death) in multivariate analyses, a practice common in many small studies that evaluate the predictive-value of various treatments or special tests, was examined. In univariate analyses, patients with nonfatal recurrent infarction did not differ with respect to age or gender from infarct-free survivors, but they more often had a history of previous myocardial infarction, congestive heart failure, angina pectoris, and diabetes; more severe pulmonary congestion was present on chest x-ray during the admission, and a non-Q wave index infarction was more frequent. Patients with either a fatal or nonfatal recurrent infarction had more angina pectoris during follow-up (55% to 60%) compared with 27% in event-free survivors and 31% in patients who died of other cardiac causes in whom this factor could be assessed before death. In multivariate analyses, historical and clinical prognostic factors were ranked differently for fatal or nonfatal reinfarction and other cardiac causes of death; angina pectoris at follow-up was highly related to recurrent infarction (fatal or nonfatal), along with a history of diabetes, and a non-Q wave index infarction. These factors were not independently related to other causes of cardiac death.(ABSTRACT TRUNCATED AT 250 WORDS)

We determined in-hospital and 1-year prognoses after acute myocardial infarction (MI) in 5,839 consecutive patients derived from 14 of 21 coronary care units in Israel during 1981-1983. Age-adjusted in-hospital mortality was 23.1% in 1,524 women and 15.7% in 4,315 men (p less than 0.0005). One-year age-adjusted mortality rates in patients surviving hospitalization were 11.8% in women and 9.3% in men (p = 0.03). Cumulative age-adjusted 1-year mortality rates were 31.8% in women and 23.1% in men (p less than 0.0005). Relative odds of mortality, covariate-adjusted for major prognostic factors that included age, prior MI, congestive heart failure, and infarct location by electrocardiogram, indicated that female gender was independently and significantly associated with increased mortality both during hospitalization (relative odds, 1.72; 95% confidence interval, 1.45-2.04) and at 1 year after discharge (relative odds, 1.32; 95% confidence interval, 1.05-1.66). In separate multivariate analyses for each gender, a major factor that emerged as a predictor of outcome in women, but not in men, was a reported history of diabetes mellitus, both for in-hospital mortality and for 1-year mortality. However, even in the nondiabetics in this population, female gender was a significant, independent predictor of in-hospital mortality. The findings of the present study substantiate that women fare worse than men after suffering an acute MI, that increased age does not fully account for the increased mortality in women, and that diabetic women are at particularly high risk once MI has occurred.

In order to predict the residual stenosis in coronary thrombolysis, the factors easily obtained from clinical history--age, gender, history of angina before acute myocardial infarction (AMI), family history, hypertension, diabetes, hypercholesterolemia, smoking, and interval between onset of AMI and recanalization--were observed in 114 patients with successful coronary thrombolysis. In 55 patients with angina before AMI, 29 patients had residual stenosis greater than or equal to 75% and 26 patients had residual stenosis less than 75%. In 59 patients without angina before AMI, 15 patients had residual stenosis greater than or equal to 75%, and 44 patients had residual stenosis less than 75%. The presence or absence of angina before AMI was the main variable that discriminated the groups of residual stenosis of more or less than 75%, which was the only significant independent variable to predict the residual stenosis. These data suggest that the presence of angina pectoris before AMI is likely to be associated with a significant degree of residual stenosis after thrombolysis.

The Copenhagen City Heart Study is a prospective cardiovascular population study designed to evaluate incidence of, and risk factors for, cardiovascular disease. A random sample, comprising approximately 20,000 people, were invited to participate. Initial information about potential risk factors was collected during 1976-78 (attendance rate 74%); data about 389 new cases of first acute myocardial infarction (AMI) was obtained from a second survey in 1981-83, as well as from hospital and death registers up to 31 December 1983. The average observation period was 6.5 years. Cox's regression model was used for data analysis. Some 'basic' factors, namely age, sex, family history of AMI, early parental death, height, earlobe crease, length of school education, income and living alone or with a partner were dealt with in a previous paper and are among the potential risk factors for AMI included in the Copenhagen City Heart Study. In this analysis we also include life-style characteristics, some biological traits and disease conditions. An increased risk for first AMI among smokers was graded: the estimated relative risk (ERR) for heavy smokers consuming more than 29g tobacco per day was 2.8 relative to non-smokers. Alcohol intake of five or more drinks per day was associated with a decreased risk, an ERR of 0.6 relative to those who did not drink alcohol daily. Physical inactivity during work but not at leisure was associated with increased risk (ERR 1.4) as was body mass index where the risk was mediated mainly through blood pressure and plasma triglycerides. Oral contraception was not associated with an increased risk, whereas with diabetes the risk increased (the ERR for diabetes being 1.8). Plasma cholesterol above the level of approximately 7 mmol l-1 proportionally increased risk; the ERR in the 1.5% with the highest level was 3.7. A low triglyceride level was associated with low risk; the ERR in the fifth of the study population with the lowest level was 0.6. Elevated blood pressure also proportionally increased risk. Subjects on antihypertensive drug treatment had higher risk than non-treated subjects with similar blood pressure. The effect of socioeconomic factors described in the previous paper was not mediated through their influence on the risk factors included in the present analysis.

The Stroke Register was established in 1984 in Heidelberg, as a part of the MONICA Project, covering the same population (approximately 601,000) as the Acute Myocardial Infarction Register. In the present analysis, the data for men and women (aged 25-64) for 1985 and 1986 are presented. During the two years, 303 men and 143 women were registered. The overall age-standardized attack rate was 127.2/100,000 for men and 52.8/100,000 for women, and the age-standardized incidence was 97.4/100,000 in men and 42.9/100,000 in women. The proportion of first stroke was 76.5% in men and 81% in women. The 28-days mortality was 12% for men and 19% for women. Hypertension, diabetes mellitus, smoking and heart disease (coronary heart disease, rhythm disturbances) were identified as risk factors for stroke. Among the registered victims of stroke, 61% of the men and 67% of the women had a history of hypertension. In men, a high prevalence of smokers, 54% was found (33.9% in the total population in the same age range). In women, the prevalence of smokers is nearly the same as in the total population. Diabetes mellitus was present in 23% of men and in 40% of women, and hyperlipidaemia in 30% of men and in 18% of women.

As predicted, coronary artery disease is being recognized with increasing frequency in the town hospitals in Papua New Guinea. This report contains the clinical characteristics of 20 patients with acute myocardial infarction admitted to the Port Moresby General Hospital. The clinical features of acute myocardial infarction were typical of the disease anywhere. The seemingly rare frequency of angina of effort in this group of patients is an interesting observation. The high in-hospital case fatality rate observed here is alarming. Urban dwelling, the male gender, smoking and diabetes were important risk factors in the development of this disease in these patients.

To determine the evolution of acute myocardial infarction in patients with diabetes we study 207 consecutive patients with myocardial infarction. Using WHO's criteria 23% of our cases were diagnosed of diabetes mellitus. Diabetic patients were older than non diabetic (67.9 +/- 10 years vs. 62.4 +/- 11 years, p less than 0.05) and had a higher ratio of females (52% vs. 21%, p less than 0.001). Cigarette smoking was infrequent in diabetic population. Incidence of other risk factors was comparable. Despite an increased proportion on no q-wave myocardial infarction in the diabetic patients (12.5% vs. 6.9%, p NS), the site of infarction was similar into the two groups. Acute phase mortality was higher in the diabetic group (37.5% vs. 16.3%, p less than 0.001). This increased mortality is, partially, related to an increased incidence of pump failure, but a multivariate analysis using stepwise logistic regression, selected diabetes as an independent predictor of prognosis. Survivors were followed for 41 +/- 20 months; diabetic patients showed a poor prognosis with a higher incidence of congestive heart failure (42.8% vs. 13.7%, p less than 0.01), reinfarction (16.6% vs. 8.5%) and death. Cox proportional hazard model selected diabetes as an independent predictor of survival. We conclude that patients with diabetes mellitus constitute a subgroup into the myocardial infarction population; this subgroup had greater mortality than non diabetic patients in relation to increased incidence of pump failure, but multivariate analysis indicates that other factors not considered in the present study may play a role in their poor prognosis.

Manitoba's hospital separations and physician medical files were linked for the fiscal years 1984-85 and 1985-86. The result was a study file consisting of records for 5,293 males and 3,143 females, who, during this period, suffered an Acute Myocardial Infarction (AMI), commonly called a heart attack. Merging the two types of files created a comprehensive data base for these AMI victims. The Manitoba age-sex standardized AMI rate was 38.0 per 10,000 population. Age-specific rates were higher for males than for females for all age groups. Hospitalized cases accounted for 7,201 individuals or 85.4% of AMI victims. Age-sex standardized rates of hospitalization per 10,000 population ranged from 27.1 in the Central region to 36.0 in the Westman region. The Manitoba age-specific rates of hospitalization for males in the 35-54 and 55-64 age groups were about three times the female rates for the same age groups. One quarter of AMI hospitalized victims died in hospital. The Manitoba age-specific death rates for males in the 35-54, 55-64 and 65-74 age groups were double the rates for females in the same age groups. Of the 8,436 AMI victims under study, 86.4% had at least one other concurrent medical condition such as angina, other forms of ischemic heart disease, diabetes, or hypertension. Of AMI victims, 93.8% underwent at least one of the following procedures: coronary artery bypass surgery, angiogram, electrocardiogram, cardiac catheterization, arteriography, or blood cholesterol testing. A higher percentage of procedures was performed on males than on females.

Forty one cardiac rupture complicating acute myocardial infarction (AMI) were studied in a ten-year period. The anterior AMIs are most likely to be observed with ruptures. The interval from the onset of AMI to the clinical detection of rupture was short (acute period). Some factors such as physical work in the acute period and transmural infarctions strongly infiltrated with leukocytes cause a higher frequency of rupture. Diabetes and hypertension might be predisposing factors.

This cost-benefit analysis attempts to translate the clinical findings of the Helsinki Heart Study (HHS) and published results regarding additional cardiovascular conditions into economic terms meaningful to US managed care providers. The study has the following 3 key objectives: to define the cost effectiveness of gemfibrozil in the prevention of coronary heart disease (CHD); to assess the net impact of gemfibrozil on total treatment costs for CHD; and to identify those patient groups for whom gemfibrozil therapy is most cost effective. In order to reach these findings a cost-effectiveness model was constructed based on original clinical data provided by the HHS, published findings for CHD risk and cost of treatment in the US, expert opinion and extension of HHS to other cardiovascular conditions, and documented costs and treatment protocols of US Medicaid and privately managed health care programmes. The model was applied to the California Medicaid (Medi-Cal) programme to estimate costs of hyperlipidaemia therapy using gemfibrozil. In parallel, savings to Medi-Cal from averted coronary events were estimated. From these data, the net expected savings to Medi-Cal were calculated. The probability of experiencing CHD varies with cholesterol level, age, sex and risk factors such as smoking, hypertension and diabetes. Therefore, it is possible to use risk-factor profiles to define groups of individuals with low, moderate or high risk of experiencing acute myocardial infarction (AMI) or sudden cardiac death. The probability of a cardiac event within 5 years ranges from 1.1% in a 45-year-old low risk male to over 36% in a 55-year-old high risk male. The average total cost of CHD care was found to be US$22,271 within 5 years. Using the probability of a CHD event to calculate the expected 5-year cost of CHD care produces a range from US$242 in the 45-year-old low risk male to US$8084 in the 55-year-old high risk male. Treatment with gemfibrozil reduces the probability of AMI and sudden cardiac death events by 34%, as demonstrated in the HHS. Therefore, the corresponding probability ranges are reduced to 0.7% in the 45-year-old low risk male and 27.3% in the 55-year-old high risk male after treatment with gemfibrozil. The expected cost of a coronary event is reduced by US$82 and US$1997, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)
