While the term “disease modification” is used […]
Mortality Prediction and Outcomes in the HEART-FID Trial
The HEART-FID trial, the largest study to date to investigate intravenous iron therapy in heart failure, compared ferric carboxymaltose (FCM) to a placebo in ambulatory patients with heart failure with reduced ejection fraction as well as iron deficiency. While the trial demonstrated a modest reduction in major clinical outcomes, including all-cause mortality, this difference was not statistically […]
Pharmaco-Invasive Treatment in Younger STEMI Patients: A Comparative Analysis of the STREAM-1 and STREAM-2 Trials
The STREAM-1 trial demonstrated that full-dose tenecteplase (TNK) increased the risk of intracranial hemorrhage in elderly patients (≥75 years) with ST-elevation myocardial infarction (STEMI), while a half-dose eliminated this risk. Subsequently, the STREAM-2 trial confirmed the efficacy and safety of half-dose TNK compared to primary percutaneous coronary intervention (PPCI) in STEMI patients ≥60 years presenting within 3 hours of […]
Alberta Study Finds No Negative Impact on Cardiovascular Medication Adherence During COVID-19 Pandemic
While some studies point to a potential decline in chronic medication adherence during the COVID-19 pandemic, limited empirical evidence has been published to date. In order to address this gap, a recent CVC-led study examined whether the COVID-19 pandemic impacted adherence patterns in patients receiving chronic treatment with cardiovascular drugs. This retrospective study analyzed drug dispensation data […]
Vericiguat’s Effects in Simulated Heart Failure Trial Populations
The VICTORIA trial established that vericiguat, in comparison to placebo, significantly reduced the risk of heart failure hospitalization or cardiovascular death in patients with worsening heart failure with reduced ejection fraction (HFrEF). This study, published in ESC Heart Failure, assessed how vericiguat performed in a group of VICTORIA trial participants with baseline characteristics similar to those in the PARADIGM-HF and DAPA-HF trials.

Proteomic Analysis in Heart Failure with Preserved Ejection Fraction: Insights from VITALITY-HFpEF
Heart failure with preserved ejection fraction (HFpEF) is a complex condition that often develops in people with multiple other health problems, and is believed to arise from a network of related systemic processes. While existing protein biomarkers for HFpEF exhibit diagnostic limitations, a comprehensive protein analysis approach, known as proteomics, has the potential to improve […]
Triglycerides, Alirocumab, and Cardiovascular Outcomes Following an Acute Coronary Syndrome
Alirocumab is an injectable PCSK9 inhibitor that reduces the level of low-density lipoprotein cholesterol (LDL-C), commonly known as “bad” cholesterol. The ODYSSEY OUTCOMES trial demonstrated that, among patients with a recent acute coronary syndrome (ACS) receiving high-intensity statin therapy, alirocumab reduced the risk of recurrent ischemic cardiovascular events and lowered all-cause mortality. Using ODYSSEY OUTCOMES […]
