What is physiological heart disease?

I need a definition please.

There is no such word or phrase in the medical dictionary.
Physiology means the science dealing with the function of various parts and organs of living organisms.
Morbid physiology or pathological physiology means the study of disordered function in diseased tissues.
There may be some sense if you had asked for the definition of pathological physiology of heart disease.

The role of psychosocial factors in the cause of coronary heart disease has been investigated with increasing confidence over recent years, due to a number of developments. Large scale prospective studies of psychosocial factors assessed with standardised measures and using all the rigour of modern multivariate epidemiology have begun to produce results.

Recent research has shown that psychological risk factors play an important role in the pathogenesis of cardiovascular diseases. The so-called coronary prone behaviour pattern predominates, an important part of which is the Type A behaviour pattern.
This is characterized by a marked ambition, a constant feeling of being under pressure, due to latent aggression and to a striving to dominate.

For cerebrovascular diseases the so-called pressured pattern as a risk factor has been found to be typical which is comparable to the Type A behaviour. Psychological risk factors and their components are not equally important for different vascular diseases. Besides the explanation of the question as to how far psychological processes really are involved in the development of vascular diseases, the research on psychological risk factors serves as a foundation for psychosomatic theories.

Psychological distress, particularly depression, is being increasingly recognized as a risk factor for coronary heart disease.Depression is also associated with increased mortality risk following myocardial infarction.

This is the best definition I can find.
Take care as always!
