People of Pakistani origin in Scotland carry a 50 percent elevated risk of suffering from heart diseases.
Scots of Indian and Pakistani origin also have much greater levels of hospital admissions for both conditions than people of white Scottish ethnicity.
Those of Pakistani origin were twice as likely to be admitted to hospital with chest pain compared with white Scots, according to the University of Edinburgh study.
The research also showed that white Scots were one-fifth more likely to be admitted to hospital with angina than other white British, mainly English, living in Scotland.
However, residents in Scotland of white Irish ethnicity have similar rates of hospital admissions with angina and chest pain to those of white Scottish ethnicity
Chinese people in Scotland, in contrast to other ethnic groups, have the lowest levels of hospital admissions for chest pain and angina.
The differences in admissions are most likely due to lifestyle-related factors such as diet, physical activity and smoking.
The study combined Census data on ethnicity and NHS data for hospital discharges, and community and hospital deaths.
Such findings are important as they can help with both prevention as well as planning of healthcare services on a European-wide scale.
"Scots have among the highest rates of heart attacks in the world, but we have shown that, among residents of Scotland, those of Pakistani origin followed by those of Indian origin have beaten them," said Professor Raj Bhopal, of the University of Edinburgh's Centre for Population Health Sciences.
"The most amazing thing is how the Chinese population has such low rates of heart disease-everyone in Scotland has something to learn from them. "
The study has been published in the European Journal of Cardiovascular Prevention and Rehabilitation.
