摘要:
Changes in mortality from heart disease, cancer, and stroke over recent decades in many countries have received much attention. However, comprehensive and concurrent analyses of these trends and their effect on total mortality have been lacking. Moreover, the extent to which the trends for one disease may relate to those for another disease is unknown. Concordance of trends for major diseases would suggest that they have common causes and thus may be responsive to the same preventive measures.Methods and ResultsAge-adjusted death rates for total mortality and mortality from heart disease, stroke, lung cancer, and cancer other than lung cancer were obtained for the years 1950 to 1987 in 27 countries by sex and ages 35 to 74 years from the World Health Organization statistical reports. Concordance of mortality trends was assessed for ages 35 to 74 between 1950 and 1983 through visual inspection and semiquantitative measurements of percentage change over time. The epidemic increase in heart disease mortality ended in the 1960s or 1970s in most industrialized countries; death rates often declined very steeply. Stroke mortality also changed from an increase to a decline or from a modest to a steep decline in the 1960s or 1970s. Lung cancer mortality slopes generally changed from a steep increase to either a modest increase, a flat trend, or a decline; the changes in slope are lagging behind those for heart disease and stroke. These improvements influenced trends for total mortality. Cancer other than lung cancer trends are less distinct than those for the three other causes of mortality. Yet, testing them for concordance with heart disease trends reveals that they are mostly concordant on a time-lag analysis that assumes that heart disease responds more rapidly to a change in lifestyle or environment than cancer. Trends for heart disease and lung cancer in men also tend to be concordant on time-lag analysis. Heart disease and stroke trends have become more concordant with time.ConclusionsTrends for mortality from heart disease, stroke, lung cancer, and, less distinctly, cancer other than lung cancer, tend to be similar in different countries, leading to a corresponding similarity in total mortality trends. An analysis of trends for pairs of diseases within countries indicates a tendency toward concordance of trends, suggesting the existence of common causes amenable to the same preventive measures. This analysis of international mortality trends is intended to stimulate further research along these lines, as a guide to preventive and therapeutic action.

摘要:
The WHO MONICA Project is a 10-year study that monitors deaths due to coronary heart disease (CHD), acute myocardial infarction, coronary care, and risk factors in men and women aged 35 to 64 years in defined communities. This analysis of methods and results of coronary event registration in 1985 through 1987 provides data on the relation between CHD morbidity and mortality.Methods and ResultsFatal and nonfatal coronary events were monitored through population-based registers. Hospital cases were found by pursuing admissions (“hot pursuit”) or by retrospective analysis of discharges (“cold pursuit”). Availability of diagnostic data on identified nonfatal myocardial infarction was good. Information on fatal events (deaths occurring within 28 days) was limited and constrained in some populations by problems with access to sources such as death certificates. Age-standardized annual event rates for the main diagnostic group in men aged 35 to 64 covered a 12-fold range from 915 per 100 000 for North Karelia, Finland, to 76 per 100 000 for Beijing, China. For women, rates covered an 8.5-fold range from 256 per 100 000 for Glasgow, UK, to 30 per 100 000 for Catalonia, Spain. Twenty-eight-day casefatality rates ranged from 37% to 81% for men (average, 48% to 49%), and from 31% to 91% for women (average, 54%). There was no significant correlation across populations for men between coronary event and case-fatality rates (r= −.04), the percentages of coronary deaths known to have occurred within 1 hour of onset (r= .08), or the percentages of known first events (r= −.23). Event and case-fatality rates for women correlated strongly with those for men in the same populations (r= .85,r= .80). Case-fatality rates for women were not consistently higher than those for men. For women, there was a significant inverse correlation between event and case-fatality rates (r= −.33,P< .05), suggesting that nonfatal events were being missed where event rates were low. Rankings based on MONICA categories of fatal events placed some middle- and low-mortality populations, such as the French, systematically higher than they would be based on official CHD mortality rates. However, rates for nonfatal myocardial infarction correlated quite well with the official mortality rates for CHD for the same populations. For men (age 35 to 64 years), approximately 1.5 (at low event rates) to 1 (at high event rates) episode of hospitalized, nonfatal, definite myocardial infarction was registered for every death due to CHD. The problem in categorizing deaths due to CHD was the large proportion of deaths with no relevant clinical or autopsy information. Unclassifiable deaths averaged 22% across the 38 populations but represented half of all registered deaths in 2 populations and a third or more of all deaths in 15 populations.ConclusionsThe WHO MONICA Project, although designed to study longitudinal trends within populations, provides the opportunity for relating rates of validated CHD deaths to nonfatal myocardial infarction across populations. There are major differences between populations in nonfatal as well as fatal coronary event rates. They refute suggestions that high CHD mortality rates are associated with high case-fatality rates or a relative excess of sudden deaths. The high proportion of CHD deaths for which no diagnostic information is available is a cause for concern.

摘要:
ThisQuick Reference Guide forClinicians contains recommendations on the care of patients with unstable angina based on a combination of evidence obtained through extensive literature reviews and consensus among members of an expert panel. Principal conclusions include the following. (1) Many patients suspected of having unstable angina can be discharged home after adequate initial evaluation. (2) Further outpatient evaluation may be scheduled for up to 72 hours after initial presentation for patients with clinical symptoms of unstable angina judged at initial evaluation to be at low risk for complications. (3) Patients with acute ischemic heart disease judged to be at intermediate or high risk of complications should be hospitalized for careful monitoring of their clinical course. (4) Intravenous thrombolytic therapy should not be evaluadministered to patients without evidence of ST segment elevation and acute myocardial infarction. (5) Assessment of prognosis by noninvasive testing often aids selection of appropriate therapy. (6) Coronary angiography is appropriate for patients judged to be at high risk for cardiac complications or death based on their clinical course or results of noninvasive testing. (7) Coronary artery bypass surgery should be recommended for almost all patients with left main disease and many patients with three-vessel disease, especially those with left ventricular dysfunction. (8) The discharge care plan should include continued monitoring of symptoms; appropriate drug therapy, including aspirin; risk-factor modification; and counseling.
