Disparities in Triple Negative Breast Cancer Among Hispanic Population Living in Latin America Versus the United States.

Introduction: Triple-negative breast cancer (TNBC) has a prevalence of 12%-24% in the Hispanic population. Previous research has demonstrated that disparities in healthcare access significantly influence patient outcomes. We aimed to compare the clinicopathological characteristics and outcomes of Hispanic females with TNBC living in Latin America (HPLA) to the Hispanic population in the United States (HPUS).

Abnormal Exercise Electrocardiography With Normal Stress Echocardiography Is Associated With Subclinical Coronary Atherosclerosis.

Background: Patients with abnormal (positive) exercise electrocardiography, but normal stress echocardiography (+ECG/-Echo), have an increased risk of adverse cardiovascular events compared with patients with a normal (negative) ECG and a normal stress Echo (-ECG/-Echo). However, it is unclear if +ECG/-Echo discordance is associated with a greater burden of subclinical coronary atherosclerosis.

Methods: Project Baseline Health Study participants who underwent a stress Echo and coronary artery calcium (CAC) scan were stratified by stress Echo result: -ECG/-Echo or +ECG/-Echo.

Changes in functional capacity of heart failure patients following a cardiac rehabilitation program.

Purpose: To evaluate the effectiveness of a cardiac rehabilitation (CR) program on functional capacity in patients with heart failure at a high-complexity hospital in the city of Cali during the period from 2017 to 2023.

Methods: A retrospective descriptive study that included 127 patients over 18 years of age diagnosed with heart failure, who completed 36 rehabilitation sessions with complete records of the 6-minute walk test (6MWT), anthropometric and physiological measurements at the beginning and end of the program. Categorical variables were summarized as absolute frequencies and percentages.

Sacubitril/valsartan versus valsartan initiation in patients naïve to renin-angiotensin system inhibitors: Insights from PARAGLIDE-HF.

Aims: Whether prior treatment with angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) modifies efficacy and safety of sacubitril/valsartan (Sac/Val) in patients with heart failure (HF) and ejection fraction (EF) >40% is unclear, thus Sac/Val according to ACEi/ARB status at baseline was assessed.

Methods And Results: This was a pre-specified analysis of Prospective comparison of ARNI with ARB Given following stabiLization In DEcompensated HFpEF (PARAGLIDE-HF), a double-blind, randomized controlled trial of Sac/Val versus valsartan, categorizing patients according to baseline ACEi/ARB status. The primary endpoint was time-averaged proportional change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) from baseline through weeks 4 and 8.
