CRP and heart failure: Our findings showed that elevated C-reactive protein (CRP) had a statistically significant superiority in predicting all-cause mortality (OR: 3.22, 95% CI: [2.71, 3.84], <i>p</i> < 0.00001), cardiovascular death (OR: 3.26, 95% CI: [2.30, 4.61], <i>p</i> < 0.00001), major adverse cardiovascular events (MACEs) (OR: 2.85, 95% CI [2.08, 3.90], <i>p</i> < 0.00001), heart failure (OR: 2.29, 95% CI: [1.48, 3.54], <i>p</i> = 0.0002), recurrent myocardial infarction (OR: 1.76, 95% CI: [1.28, 2.43], <i>p</i> < 0.001), and restenosis (OR: 1.71, 95% CI: [1.18, 2.47], <i>p</i> = 0.004).
