Background:
The utilization of mechanical circulatory support (MCS) for percutaneous coronary intervention (PCI) using percutaneous ventricular assist device (PVAD) or intra-aortic balloon pump (IABP) has been increasing. We sought to evaluate the outcome of coronary intervention using PVAD compared with IABP in noncardiogenic shock and nonacute myocardial infarction patients.
Method:
Using the National Inpatient Sampling (NIS) database from 2005 to 2014, we identified patients who underwent PCI using ICD 9 codes. Patients with cardiogenic shock, acute coronary syndrome, or acute myocardial infarction were excluded. Patient was stratified based on the MCS used, either to PVAD or IABP. Univariate and multivariate logistic regression were performed to study PCI outcome using PVAD compared with IABP.
Results:
Out of 21,848 patients who underwent PCI requiring MCS, 17,270 (79.0%) patients received IABP and 4,578 (21%) patients received PVAD. PVAD patients were older (69 vs. 67, p < .001), were less likely to be women (23.3% vs. 33.3%, p < .001), and had higher rates of hypertension, diabetes, hyperlipidemia prior PCI, prior coronary artery bypass graft surgery, anemia, chronic lung disease, liver disease, renal failure, and peripheral vascular disease compared with IABP group (p ≤ .007). Using Multivariate logistic regression, PVAD patients had lower in-hospital mortality (6.1% vs. 8.8%, adjusted odds ratio [aOR] 0.62; 95% CI 0.51, 0.77, p < .001), vascular complications (4.3% vs. 7.5%, aOR 0.78; 95% CI 0.62, 0.99, p = .046), cardiac complications (5.6% vs. 14.5%, aOR 0.29; 95% CI 0.24, 0.36, p < .001), and respiratory complications (3.8% vs. 9.8%, aOR 0.37; 95% CI 0.28, 0.48, p < .001) compared with patients who received IABP.
Conclusion:
Despite higher comorbidities, nonemergent PCI procedures using PVAD were associated with lower mortality compared with IABP.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
