Day-to-day blood pressure variability predicts poor outcomes following percutaneous coronary intervention: A retrospective study

Figure 1 Adjusted odds ratios with 95% confidence intervals from logistic regressions of preoperative blood pressure variability predicting outcomes after percutaneous coronary intervention. Odds ratios were controlled for age, sex, smoking status, diagnoses of hypertension or diabetes, prior cardiovascular disease, prior myocardial infarction, prior coronary artery bypass graft, prior percutaneous coronary intervention (PCI) left ventricular ejection fraction (LVEF), prior creatinine, anginal class, on anti-anginal medications, indication, and average systolic or diastolic blood pressure. Due to some missing values, myocardial infarction was not adjusted for PCI LVEF and creatinine. MACE: Major adverse cardiac events; MI: Myocardial infarction; LC: Largest change; SD: Standard deviation.

Figure 2 Receiver operating characteristic curves for blood pressure variability predicting major adverse cardiac events, readmission, and myocardial infarction for patients one year after undergoing percutaneous coronary intervention. A: Major adverse cardiac events blood pressure variability (BPV); B: Readmission BPV; C: Myocardial infarction BPV. SD: Standard deviation.

Figure 3 Mean blood pressure variability by age and major adverse cardiac event status of patients one year after undergoing percutaneous coronary intervention. BPV: Blood pressure variability; LC: Largest change; MACE: Major adverse cardiac events; SD: Standard deviation.
