Adult heart disease in Mt Hagen: a study of 154 patients
1Mt Hagen Hospital, Papua New Guinea.
Insights
Cardiovascular disease is prevalent in Papua New Guinea
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Background:
- Previous studies on cardiovascular disease in Papua New Guinea have not focused on the highlander population.
- Understanding the specific burden of heart conditions in this demographic is crucial for targeted healthcare interventions.
Purpose of the Study:
- To investigate the prevalence and nature of cardiovascular diseases among the highlander population in Papua New Guinea.
- To identify the most common cardiac conditions and their characteristics in this specific ethnic group.
Main Methods:
- Retrospective review of 154 cardiac patients presenting to the Mt Hagen adult outpatient department over one year.
- Exclusion criteria included non-highlanders, patients under 12, and secondary heart disease (anemia, vascular).
Main Results:
- Heart disease significantly contributes to outpatient visits and hospital admissions.
- Cor pulmonale secondary to chronic lung disease was the most frequent condition, exceeding other reported frequencies and causing most congestive heart failure.
- Valvular heart disease, including congenital bicuspid aortic valves, was common and severe. Arrhythmias and conduction disturbances were also prevalent. Ischemic heart disease and hypertension were likely underreported.
Conclusions:
- Cor pulmonale and valvular heart disease are significant cardiovascular concerns in the Papua New Guinea highlander population.
- The findings highlight the need for specific public health strategies and clinical management approaches for heart disease in this region.
- Further research is warranted to accurately assess the prevalence of conditions like ischemic heart disease and hypertension.
Abstract:
Although several previous studies have been done on the nature and prevalence of cardiovascular disease in Papua New Guinea no study has looked exclusively at a highlander population. This article reviews 154 cardiac patients who first presented to the Mt Hagen adult outpatient department over a period of one year. The study excluded non-highlanders, patients under 12 years of age, and patients with heart disease secondary to anaemia or diseases of the blood vessels. Heart disease was found to constitute a significant proportion of outpatient visits and admissions. Cor pulmonale secondary to chronic lung disease was the commonest condition seen, occurring in higher frequency than reported elsewhere, and accounting for the majority of cases of congestive heart failure. Valvular heart disease was also common, often presenting in a precocious and severe form. Congenital bicuspid aortic values were important in the generation of aortic valve disease in this population. Arrhythmias and conduction disturbances were also common. Diseases of the myocardium and pericardium occurred infrequently and were of the same nature as those reported in other studies in Papua New Guinea. Hypertension was probably underreported in this study, with renal disease being a contributing factor in the cases seen. Ischaemic heart disease represented a small number of the total cases, but was probably underreported.
