Abstract
The importance of the most common risk factors in patients under 35 years old, who have had clinical syndromes of ischemic heart disease, such as angina pectoris and/or myocardial infarction (MI) and/or intermediary syndrome, and in whom coronary angiography has been performed, has been reviewed in a retrospective study made under the auspices of the Swiss Cardiac Society (SCS). The results of this survey are compared with those of a national control population study (PNR) carried out in four cities in Switzerland (Nyon, Vevey, Aarau, Soluthurn) on a population of about the same age group (25–40 years).
