Abstract

Cerebrovascular and coronary disease are characterized by some common aspects. Indeed the same risk factors relate to coronary heart disease and to cerebrovascular disease. However, there may be differences in the pathogenesis of atherosclerotic lesions in coronary and cerebral arteries. In fact some populations are characterized by a high incidence of ischaemic stroke and a low incidence of myocardial infarction, while in other populations there is an opposite trend. These differences could be explained on the basis of: genetic risk factors; a different prevalence of risk factors; a different reactivity of the coronary and cerebral arteries to risk factors; anatomical differences concerning coronary and extracranial cerebral arteries with respect to intracranial cerebral arteries. Atherosclerosis is undoubtedly a systemic disorder and its genetic and environmental causal factors are only partly known. The variable incidence of cerebrovascular and coronary heart disease in the same population or in different populations as well as the different nature of atherosclerotic plaques are probably related to the different prevalence of the causal factors, even though these may not always be identified.

      LDL oxidation leads to incorporation of cholesterol deposits into the subendothelial layer of the blood vessels. Injury to the intimal layer from accumulation of these deposits can cause platelet aggregation and thrombus formation that may lead to stenosis of the vessel.3 Rupture of plaques can lead to acute ischemic events as well as occlusion at the site of the stenosis.

      Arterial disease may differ among vascular beds, particularly smaller arteries and arterioles (33). Plaque composition in the smaller cerebral arteries suggests a more fibrotic process than in the coronary arteries, which have more lipid-rich cores and typical atheromatous lesions (34). In addition, arteriolar lesions are characterized by hyalinosis instead of lipid.

      Atherosclerosis progression is characterized by development of plaque on the insides of arteries, which later hardens and narrows the arteries, leads to reduced supply of oxygen-rich blood to organs and other parts of the body. This can lead to various serious cardiovascular complications like heart attack, stroke, or even death (Paolo et al., 1995). Fig. 1 shows the development of atherosclerotic-plaque in the coronary artery.

      Citation Excerpt :

      The disproportionately high rate of uncontrolled hypertension, diabetes mellitus, and hyperlipidaemia in the African-American population20,21 partly accounts for the increased incidence of intracranial atherosclerosis. The high rate in the Japanese population is attributed to the high frequency of hypertension with paradoxically low rates of hyperlipidaemia.22,23 In the Chinese population, the rates of hypertension, diabetes mellitus, and hyperlipidaemia are not higher than that in the white population,24–26 and therefore the excess burden of intracranial atherosclerosis is unaccounted for.
