Nutrition in primary and secondary prevention of cardiovascular risk in the continental and Mediterranean regions of Croatia

BACKGROUND: The aim of this observational study was to evaluate the effect of Mediterranean and continental nutrition on cardiovascular risk in patients with acute and chronic coronary heart disease in Croatia. METHODS: The study included 1284 patients who were hospitalized in a 28-month period due to acute or chronic ischaemic heart disease in hospitals across Croatia. An individual questionnaire was prepared which enabled recording of various cardiovascular risk factors. RESULTS: Patients with chronic coronary artery disease have a better index of healthy diet than patients with acute coronary disease. Women have a better index of diet than men in both Croatian regions. When the prevalence of risk factors (impaired glucose tolerance, diabetes mellitus types I and II, hypercholesterolaemia, hypertriglyceridaemia and hypertension) in patients with Mediterranean and continental nutrition is compared, a trend is seen for patients who have risk factors to consume healthier food. CONCLUSION: The Mediterranean diet is associated with reduced risk of developing cardiovascular disease. This effect is more evident in patients with known cardiovascular disease.
