Apparent absence of stroke and ischaemic heart disease in a traditional Melanesian island: a clinical study in Kitava.
On the island of Kitava, Trobriand Islands, Papua New Guinea, a subsistence lifestyle, uninfluenced by western dietary habits, is still maintained. Tubers, fruit, fish and coconut are dietary staples. Of the total population, 1816 subjects were estimated to be older than 3 years and 125 to be 60-96 years old. The frequencies of spontaneous sudden death, exertion-related chest pain, hemiparesis, aphasia and sudden imbalance were assessed by semi-structured interviews in 213 adults aged 20-96. Resting electrocardiograms (ECG's) were recorded in 119 males and 52 females. No case corresponding to stroke, sudden death or angina pectoris was described by the interviewed subjects. Minnesota Code (MC) items 1-5 occurred in 14 ECG's with no significant relation to age, gender or smoking. ST items (MC 4.2 and 4.3) were found in two females and Q items (MC 1.1.2, 1.3.2 and 1.3.3) in three males. Stroke and ischaemic heart disease appear to be absent in this population.
