The American Heart Association, American College of Cardiology, and American Society of Hypertension have updated goals for treatment of hypertension in patients with coronary artery disease (CAD). The <140/90-mmHg BP target is reasonable for the secondary prevention of cardiovascular events. A lower target BP (<130/80 mmHg) may be appropriate in some individuals with CAD, previous myocardial infarction, stroke or transient ischemic attack, or CAD risk equivalents (carotid artery disease, peripheral arterial disease, abdominal aortic aneurysm). In patients with an elevated diastolic blood pressure (DBP) and CAD with evidence of myocardial ischemia, the BP should be lowered slowly, and caution is advised in inducing decreases in DBP to <60 mmHg in any patient with diabetes mellitus or who is >60 years of age. In older hypertensive individuals with wide pulse pressures, lowering systolic blood pressure (SBP) may cause very low DBP values (<60 mmHg). This should alert the clinician to assess carefully any untoward signs or symptoms, especially those resulting from myocardial ischemia. In patients >80 years of age, a reasonable BP target is <150/80 mmHg. Octogenarians with heart failure should be checked for orthostatic changes with standing, and an SBP <130 mm Hg and a DBP <65 mm Hg should be avoided. Guideline on the treatment of hypertension in primary prevention is in process.
