Is Sodium Bicarbonate or N-Acetyl-Cysteine Effective in Preventing Contrast-Induced Nephropathy?

In a recent study published in the New England Journal of Medicine, it was found that amongst patients undergoing angiography, sodium bicarbonate is not better than sodium chloride  and neither is acetylcysteine better than oral placebo in the prevention of a composite outcome of death, need for dialysis, or persistent kidney injury. The treatment was also ineffective in reducing the risk of contrast-associated acute kidney injury.

Does Magnitude of CRP Level Reduction Correlate With Cardiovascular Mortality?

In a recent study published in The Lancet, it has been found that the magnitude of reduction in C Reactive Protein (CRP) levels due to treatment with Canakinumab, an interleukin 1β targeting monoclonal antibody, may directly correlate with a decrease in major cardiovascular events in post-myocardial infarction (MI) patients, even in the absence of an alteration in LDL levels.

Acute Myocardial Infarction after Laboratory-Confirmed Influenza Infection

In a recent retrospective cohort study published in the New England Journal Medicine, a significant association was found between acute respiratory infections, particularly influenza, and the occurrence of acute myocardial infarction (MI) in the following week. The study also highlights the increased risk in older patients and in those who are hospitalized for the first time for an MI.

S-LAAO Reduces Thromboembolism in AFib Patients After Heart Surgery

In a recent retrospective cohort study published in the Journal of American Medical Association conducted on patients with atrial fibrillation (AF) undergoing cardiac surgery, surgical left atrial appendage occlusion (S-LAAO) as compared with no surgical left atrial appendage occlusion (no S-LAAO) was significantly associated with lower risk of readmission for thromboembolism.  Continue reading

D-dimer Level is Associated With Increased Long-term Cancer Incidence and All-cause Mortality

According to a recently published article in Circulation, it was found that D-dimer level is an independent predictor of the long-term (up to 16 years) risk of arterial and venous events, cause-specific mortality, and the incidence of new cancers. The results of the study are based on a  subanalysis of the LIPID trial. Continue reading

Does Marijuana Use Impact Cardiovascular Health?

With the increasing use and the legalization of marijuana in several states of USA, there is a need to evaluate its impact on the health. To explore this, a systematic review was recently published in Annals of Internal Medicine by Ravi et al. In the study, the investigators studied the association between marijuana use and cardiovascular outcomes. The authors concluded, “Evidence examining the effect of marijuana on cardiovascular risk factors and outcomes, including stroke and myocardial infarction, is insufficient”. Continue reading

Novel Echo Markers In Stroke Risk Stratification In AFib

The assessment of left atrial reservoir strain and P-wave to A’ duration on tissue Doppler imaging provides additional risk stratification for stroke after initial CHA2DS2-VASc scoring, according to a study published in the European Heart Journal, and may prove helpful in guiding decisions about anticoagulation for patients after the diagnosis of atrial fibrillation.
