Insights
In 1995, heart failure (HF) affected 9.38% of hospitalized patients at INCOR. Ischemic heart disease was the leading cause, with higher mortality in very young and elderly patients.
Area of Science:
- Cardiology
- Public Health
Context:
- The study examines heart failure (HF) epidemiology at a major cardiac institute.
- Understanding HF incidence and causes is crucial for public health strategies.
Purpose:
- To determine the incidence, primary causes, aggravating factors, and secondary diagnoses of heart failure (HF) in 1995.
- To analyze demographic and etiological factors associated with HF hospitalization.
Summary:
- Heart failure (HF) incidence was 9.38% in 1995, with ischemic heart disease being the most common cause.
- Ischemic, dilated, and valvar heart diseases were the primary etiologies.
- Mortality rates were elevated in pediatric and geriatric populations, linked to disease complexity and comorbidity, respectively.
Impact:
- Provides baseline data on HF incidence and etiology for the specified year and institution.
- Highlights vulnerable age groups for HF, informing targeted interventions.
- Contributes to the understanding of HF burden and its management challenges.
Purpose:
To study the incidence, main causes, aggravating factors and secondary diagnoses of heart failure (HF) during 1995 at the Instituto do Coração of São Paulo.
Methods:
Data from hospitalized patients according to the PRODESP data base were analyzed. The following data were studied; age, sex, principal and secondary diagnoses, surgical procedures and mortality. To analyze the data, tables according to sex, age and main cause were built. Analysis of variance and t test were employed to verify differences between groups.
Results:
In 1995, 903 out of 9620 patients were hospitalized due to HF. The majority were male (60.4%) and the patients' age was between two days and 98 years old (mean 52.6). Ischemic (32.6), dilated (25.8%) and valvar heart disease (22%) were the main causes of HF. 32.1% were submitted to correction of the HF main cause, specially those with valvar heart disease (62.3%). There was greater incidence of multiple diagnoses in aged patients. The mortality was greater in patients younger than 20 and in those older than 80 years old.
Conclusion:
The incidence of HF at INCOR during 1995 was 9.38%. Ischemic myocardiopathy was the most frequent HF cause. The mortality was greater among children, probably because of heart disease complexity and, in the above-80 group due to the greater comorbidity.
