Specifically regarding cardio vascular disease:
Mortality rates from CHD are 46 per cent higher for men and 51 per cent higher for women of South Asian origin than in the non-Asian population.
In more than 90% of cases, the risk of a first heart attack is related to potentially modifiable risk factors, including smoking, poor diet, obesity/overweight, and insufficient physical activity.

Diet and lack of exercise are perhaps generic problems for socially disadvantaged groups. People of South Asian origin living in the UK, for instance, tend to have low levels of physical activity and fitness compared to the general population.
As with the general population, smoking prevalence in Black and other minority groups tends to decrease with age with the highest rates in those aged 16-34. Exceptions are Black Caribbean and South Asian men in whom prevalence is highest in those aged 35-54.

Is there inequality in health care?
Evidence shows that South Asians are less likely to be prescribed lipid lowering medication (for reasons that are as yet unclear) and more likely to decline and drop out from cardiac rehabilitation programmes. In addition they are more likely to present with atypical symptoms after myocardial infarction, which may delay diagnosis and optimal intervention.
The observed inequality may partially be a result of the “attitude of not taking advantage of the health service, ”lack of awareness of coronary heart disease,” and the “linguistic and cultural barriers” seen in this population.
