Patients scheduled for elective coronary angiography due to chronic coronary syndrome are recruited at admission to hospital before the coronary anatomy is known. Immediately after coronary angiography measures thermo-dilution derived flow indices are obtained in the left left anterior descending artery (LAD). The patients are followed through telephone-calls and medical records at 1 and 2 years after inclusion and at completion of the study. The hypothesis is that elevated index of microcirculatory resistance (IMR),(\>25) is associated with all-cause death, myocardial infarction (MI) and hospitalization due to congestive heart failure (CHF). The primary analysis is the relationship between IMR and the composite outcome all-cause death, MI and hospitalization due to CHF.
