Abstract: Introduction: Aggressive lowering of diastolic blood pressure (DBP) can occur at the expense of myocardial perfusion, particularly in the presence of coronary artery disease (CAD). Methods: We analysed data from 12,965 consecutive patients undergoing percutaneous coronary intervention (PCI) between 2009 and 2018 from the Melbourne Interventional Group registry who had pre-procedural systolic blood pressure (SBP) <140 mmHg. Patients with ST-elevation myocardial infarction, cardiogenic shock and out-of-hospital arrest were excluded. Patients were stratified into four groups according to DBP: <70 mmHg, 70-79 mmHg, 80-89 mmHg and >89 mmHg. Mortality data were derived from the National Death Index. Results: Patients with DBP <70 mmHg were older, were more likely to be women, have diabetes, renal impairment, prior myocardial infarction, left ventricular dysfunction, multi-vessel disease, peripheral and cerebrovascular disease (all p<0.001). There was no difference in in-hospital or 30-day major adverse cardiovascular events, but patients with DBP <70 mmHg had lower long-term survival on NDI-linkage (Figure). However, on multivariable analysis, DBP <70 mmHg was not an independent predictor of mortality (HR 1.0, 95% CI 0.86-1.15). Conclusions: In patients with well controlled SBP undergoing PCI, lower DBP is associated with higher long-term mortality, related to a greater burden of co-morbidities and higher risk profile.
