Table 1. Demographic data, prevalence of PICA-VA and the cardiovascular risk factors in patients and controls.
| Patients | Control | P value | |
|---|---|---|---|
| (n = 80) | (n = 80) | ||
| Age | 70.7±10.7 | 70.7±10.7 | |
| (35–87) | (35–87) | ||
| Gender (M/F) | 67/13 | 67/13 | |
| PICA-VA | 15 (19%) | 5 (6%) | 0.0168 |
| Coronary artery disease | 12 (15%) | 5 (6%) | 0.0725 |
| Hyperlipidemia | 30 (38%) | 10 (13%) | 0.0003 |
| Hypertension | 64 (80%) | 29 (36%) | <0.0001 |
| Diabetes Mellitus (DM) | 39 (49%) | 6 (8%) | <0.0001 |
PICA-VA = posterior inferior cerebellar artery (PICA) termination of vertebral arteryThe difference in PICA-VA between groups remained statistical significance (p = 0.0465) after adjusted for history of hyperlipidemia, hypertension and DM.
