Arterielle hypertonie bei patienten mit koronarer herzerkrankung

Arterial hypertension is the most important risk factor for coronary artery disease (CAD). There is a high coincidence of both diseases, whereby both impair coronary microcirculatory function synergistically, which can be measured functionally by decreased coronary flow reserve. This dysfunction leads to permanent damage to the left ventricular myocardium. Lifestyle changes play a central role in the primary and secondary prevention of CAD. Additionally, there are well-established options for antihypertensive drug therapy, which should be combined with aspirin and statins. Pharmacological treatment should follow distinctive blood pressure goals in relation to the severity of CAD. Particular attention is paid in this context to the relation between diastolic blood pressure values and cardiovascular endpoints, which displays a j-shaped curve with the lowest risk at levels between 70 and 90 mmHg.
