Table 3. Cardiovascular disease in the Ghanaian study sample (age≥50 years).

	Males		Females
Electrocardiographic investigations	(n = 168)		(n = 439)
Myocardial infarction
definite	1.8%	(0.6–5.1)	0.9%	(0.4–2.3)
possible	4.2%	(2.0–8.4)	2.1%	(1.1–3.8)
Myocardial ischaemia-like changes
definite	13.7%	(9.3–19.7)	10.0%	(7.6–13.2)
minor	2.4%	(0.9–6.0)	3.2%	(1.9–4.6)
Clinical investigations	(n = 480)		(n = 444)
Ankle-arm index	1.16	(1.10–1.24)	1.14	(1.06–1.22)
Peripheral arterial disease	2.3%	(1.3–4.1)	3.4%	(2.1–5.5)

Prevalences are given as percentages (95% confidence intervals) and distributions are given as medians (interquartile ranges), all for those aged 50 years and older. Peripheral arterial disease has been defined as an ankle-arm index below 0.9.
