Cardiovascular event rates and mortality according to achieved systolic and diastolic blood pressure in patients with stable coronary artery disease: an international cohort study: In patients with hypertension and coronary artery disease from routine clinical practice,
systolic blood pressure of less than 120 mm Hg and diastolic blood pressure of less
than 70 mm Hg were each associated with adverse cardiovascular outcomes, including
mortality, supporting the existence of a J-curve phenomenon. This finding suggests
that caution should be taken in the use of blood pressure-lowering treatment in patients
with coronary artery disease.
