Ivabradine Versus Beta-Blockers in Mitral Stenosis in Sinus Rhythm: An Updated Meta-Analysis of Randomized Controlled Trials.

Background: Symptoms of mitral stenosis (MS) are worsened during tachycardia and exercise. Beta-blockers are used in controlling heart rate (HR) in MS, resulting in symptom improvement, but coming with significant side effects. Ivabradine has a selective action on the sinus node devoid of the usual side effects of beta-blockers.

Red Cell Distribution Width and Mortality in Patients With Acute Coronary Syndrome: A Meta-Analysis on Prognosis.

Background: Red cell distribution width (RDW), a routine component of the complete blood count (CBC), measures variation in the size of circulating erythrocytes. It has been associated with several clinical outcomes in cardiovascular disease. We sought to strengthen the association between RDW and mortality in patients admitted for acute coronary syndrome (ACS) by pooling together data from available studies.

Chronic Heart Failure Clinical Practice Guidelines' Class 1-A Pharmacologic Recommendations: Start-to-End Synergistic Drug Therapy?

Background: Chronic heart failure (HF) disease as an emerging epidemic has a high economic-psycho-social burden, hospitalization, readmission, morbidity and mortality rates despite many clinical practice guidelines' evidenced-based and consensus driven recommendations that include trials' initial-baseline data.

Objective: To show that the survival and hospitalization-free event rates in the reviewed chronic HF clinical practice guidelines' class I-A recommendations as initial HF drug therapy (IDT) is possibly a combination and 'start-to-end' synergistic effect of the add-on ('end') HF drug therapy (ADT) to the baseline ('start') HF drug therapy (BDT).

Methodology: The references cited in the chronic HF clinical practice guidelines of the 2005, 2009, and 2013 American Heart Association/American College of Cardiology (AHA/ACC), the 2006 Heart Failure Society of America (HFSA), and the 2005, 2008, and 2012 European Society of Cardiology (ESC) were reviewed and compared with the respective guidelines' and other countries' recommendations.
