Background: Several studies have reported that C-reactive protein (CRP), an inflammatory biomarker, predicts cardiovascular events independently of low-density lipoprotein cholesterol levels. However, no study examined whether temporal changes in CRP levels are associated with clinical events in patients with previous myocardial infarction (MI).

Methods And Results: We examined 2184 consecutive patients with previous MI and CRP data at baseline in the Chronic Heart Failure Registry and Analysis in the Tohoku district-2 (CHART-2) Study.

Background: There is no robust evidence of pharmacological interventions to improve mortality in heart failure (HF) patients with preserved left ventricular ejection fraction (LVEF) (HFpEF). In this subanalysis study of the SUPPORT Trial, we addressed the influence of LVEF on the effects of olmesartan in HF.

Methods and results: Among 1,147 patients enrolled in the SUPPORT Trial, we examined 429 patients with reduced LVEF (HFrEF, LVEF <50%) and 709 with HFpEF (LVEF ≥50%).

We examined whether an additive treatment with an angiotensin receptor blocker, olmesartan, reduces the mortality and morbidity in hypertensive patients with chronic heart failure (CHF) treated with angiotensin-converting enzyme (ACE) inhibitors, β-blockers, or both. In this prospective, randomized, open-label, blinded endpoint study, a total of 1147 hypertensive patients with symptomatic CHF (mean age 66 years, 75% male) were randomized to the addition of olmesartan (n = 578) to baseline therapy vs. control (n = 569).
