|Description:||In a study of male survivors of heart disease, researchers found that there were fewer patients who were Type A before age 55 than would have been otherwise expected. (4)|
A 1981 German study of 13,175 patients showed a prevalence of Blood Type A in all forms of heart disease examined. A relationship between erythrocytic antigens of the ABO and Rh blood systems and cardiovascular pathology was revealed by comparing the distribution of blood groups in 13,175 patients and 7,800 donors. Prevalence of A gene and Rh+ phenotype in congenital and acquired heart diseases and ischemic heart disease was found. The frequency of B gene is increased in patients with acquired heart diseases.
An eight-year study of 7662 men published in the prestigious British Medical Journal found Blood Type A is linked to a higher incidence of ischaemic heart disease, as well as having higher total serum cholesterol concentrations.

Results from the NHLBI Family Heart Study also showed a higher risk of coronary heart disease (odds ratio was 2.0 (95% confidence interval = 1.2 to 3.1) for Lewis (a-b-) versus other Lewis groups. Triglycerides were significantly higher in the Lewis (a-b-) subjects. Among women, there was also a trend towards increased risk of CHD among Lewis negative phenotypes; however, the trend is dramatically weaker than among male subjects. (1)
Additional research has also duplicated these results, supporting and adding to the weight of evidence linking Lewis negative phenotype Lewis (a-b-) as a marker of high risk for the development of ischemic heart disease. Even excluding the Lewis negative phenotype, the secretor phenotype Lewis (a-b+) was found to be a genetic marker of resistance against the development of ischemic heart disease, while ABH non-secretor status is a risk factor predisposing individuals towards heart disease.

It was found that blood-group phenotypes represent an important biophysiopathological action in regard to articular rheumatism and its cardiac consequences, in myocardial infarction and in hypertension, males only. It shows itself in: -- a significant negative association with group O and positive association with group A in the myocardial infarction; -- a significant negative association with group O and positive for the others in the valvulopathic (rheumatic) diseases; -- a positive association with A phenotype and negative with B in arterial hypertension, males only; -- no association with ABO blood-groups and congenital heart disease. (3)
In a retrospective study in 3100 patients of different ages the relationship between blood group and cardiac infarction was investigated in 450 patients. The patients were divided in two age groups: those who were 65 yr old and older and younger patients (age less than 65 yr). The predominance of blood group A in patients with cardiac infarction was highly significant in both age groups (P less than 0.005, two-tailed Chi-square test). Step-wise excluding all patients with at least one of the risk factors, hypertension, hyperuricemia, diabetes mellitus, smoking, and hyperlipemia similar results were found: the predominance of blood group A in the elderly patients with cardiac infarction was even higher than before excluding the risk factors (P less than 0.001). The predominance of blood group A was also demonstrated at a lower level in younger patients with cardiac infarction (P less than 0.05). Our investigation strongly suggests the existence of a genetic factor associated with blood group A and independent of the other risk factors which is also responsible for a greater incidence of cardiac infarction.
| ||Women Type A Other factors significantly associated with MI were hypertension, angina pectoris, diabetes mellitus, blood group A, and a history of MI or stroke before age 60 years in a mother or sibling. Factors not significantly associated with MI were obesity, history of preeclamptic toxemia, and type A personality. Xzz.>|
