Determine the frequency and relationship between ischemic heart disease (IHD) and serum cholesterol levels (SCL) in non insulin dependent diabetes mellitus (NIDDM) of the primary medical care level.
A total of 411 patients from the first medical care level were studied. The sociodemographic profile, SCL and glycemia were determined and conventional ECG was taken. The ST uneveness, ischemic T or pathological Q waves in two or more tappings was considered as IHD. Patients with history of IHD were not included.
The male:female ratio was 1.5:1. Mean SCL was 225 mg/dl (in females 240.8 +/- 56 mg/dl and 220.7 +/- 50.7 in males). In 90 patients we identified IHD (22%), with male predominance (0.85:1, F:M). In the stratified statistical analysis the SCL > or = 200 mg/dl and IHD were significantly associated. The frequency of IHD by SCL levels of 200-239 mg/dl was 24.6% (OR 2.04; CI 95% 1.03-4.07, p = 0.04) and 24.2% (OR 1.99; CI 95% 1.02-3.96, p = 0.04) for SCL of 240-300 mg/dl; in patients with SCL > 300 mg/dl, an increase of IHD to 38.7% was observed (OR 3.95; CI 95% 1.52-10.30, p = 0.002).
The hypercholesterolemia was one of the most important cardiovascular risk factors in NIDDM, in which SCL > or = 200 mg/dl must be considered strongly associated to IHD.
