Iron treatments reduce heart attacks in patients on dialysis

A new paper in Cardiovascular Research, published by Oxford University Press, indicates that iron treatments may reduce heart attacks in patients experiencing kidney failure undergoing dialysis.

Coronary artery disease is prevalent in patients with chronic kidney disease but how often heart attacks occur in patients on maintenance hemodialysis and the appropriate treatments to try to prevent heart attacks in such cases is a matter of debate. Observational studies in humans and animal studies lead some researchers to express concern that intravenous iron could increase the prevalence or severity of heart attacks. Others argue that, because iron is likely to result in more oxygen delivery, intravenous iron may reduce coronary events. But there was limited research to support this.

Speech recognizing app helps predict HF

Heart failure (HF) is a progressive condition that affects approximately 26 million people worldwide. Most patients with HF present to the hospital with fluid retention, which manifests as worsening dyspnea caused by pulmonary edema. In a recent study, researchers have developed a novel mobile app, HearO that detects changes in speech which predicts clinical congestion in patients with HF. The study findings were published in the journal JACC: Heart Failure on December 8, 2021.

Mild increase in BP tied with aortic dissection risk

Mild increase in systolic and diastolic BP can increase the risk of aortic dissection, according to a recent study published in the Circulation.

Hypertension or elevated blood pressure (BP) is an important risk factor for aortic dissection (AD); however, few prospective studies concerning this topic have been published. They investigated the association between hypertension/elevated BP and AD in two cohorts and conducted a meta-analysis of published prospective studies, including these two studies.

Preeclampsia ups risk of HF in women

A recent study in the Journal of the American College of Cardiology (JACC) has reported that women with pre-eclampsia/eclampsia are at increased risk of future heart failure (HF) for up to a decade. The study found eclampsia to be an independent risk factor for future hospitalizations for HF with preserved ejection fraction (HFpEF).

While the previous studies have shown preeclampsia to be associated with increased risk of furtire HF, the relationship between preeclampsia and HF subtypes are not well-established. To determine the same, Dominique Williams, Washington University in St Louis, St Louis, Missouri, USA, and colleagues aimed to identify the risk of HFpEF following a delivery complicated by preeclampsia/eclampsia in a retrospective cohort study.
