Heart disease of the left main coronary artery has been found to be an inherited condition. Families tend to “share” this form of heart disease.
“In our study we focused on the coronary disease pattern underlying coronary artery disease and found that, for left main coronary artery disease, 49 percent of the phenotypic variation that is due to genetic effects was inherited. This substantial heritability is even higher than that for coronary artery disease or myocardial infarction in general.”
Why is this important? It can provide for more intensive screening and treatment strategies for patients that have known heart disease …read more

Hmm… I will present this to you with no opinion or comments from me. It seems that researchers out of The Bristol Heart Institute in Britain have confirmed the belief that certain patients that have survived heart attacks and heart disease become more naturally pre-conditioned than their healthy counterparts.
… Discovered surprising responses of the heart to mock cardiac surgery in a mouse model. When the heart was stopped and restarted — mimicking the conditions used in most heart bypass surgery — scientists found hearts with coronary disease from genetically modified mice were more resistant to damage than hearts without …read more

Twice as many women as men ages 45 to 64 have undetected or “silent” myocardial infarctions, suggesting a general diagnosis problem; however, Warwick University Medical School researchers say doctor’s gender may hinder early diagnosis of heart disease in women.
This is sort of interesting. The doctors gender affects the diagnosis of heart disease. And which sex had the “quicker hand” to diagnosing coronary disease? If you guessed the female physicians then you are correct, but only towards males. The female doctors showed a clear bias in favor of male patients when considering age as a diagnostic factor, …read more
