Effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on left ventricular remodelling and longitudinal strain: a prospective observational study.

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) lower cardiovascular events in type 2 diabetes mellitus (T2DM) patients, although the mechanisms underlying these benefits are not clearly understood. Our aim was to study the effects of SGLT2i on left ventricular remodelling and longitudinal strain. METHODS: Between November 2019 and April 2020, we included 52 patients with T2DM ≥ 18 years old, with HbA1c between 6.5 and 10.0%, and estimated glomerular filtration ≥ 45 ml/min/1.73 m2. Patients were classified into SGLT2i group and control group, according to prescribed treatment by their referring physician. Conventional and speckle tracking echocardiography were performed by blinded sonographers, at baseline and after 6 months of treatment. RESULTS: Among the 52 included patients (44% females, mean age 66.8 ± 8.6 years, mean HbA1c was 7.40 ± 0.7%), 30 patients were prescribed SGLT2i and 22 patients were classified as control group. Mean change in indexed left ventricular mass (LVM) was - 0.85 ± 3.31 g/m2 (p = 0.003) in the SGLT2i group, and + 2.34 ± 4.13 g/m2 (p = 0.58) in the control group. Absolute value of Global Longitudinal Strain (GLS) increased by a mean of 1.29 ± 0.47 (p = 0.011) in the SGLT2i group, and 0.40 ± 0.62 (p = 0.34) in the control group. We did not find correlations between changes in LVM and GLS, and other variables like change in HbA1c. CONCLUSIONS: Among patients with T2DM, SGLT2i were associated with a significant reduction in indexed LVM and a significant increment in longitudinal strain measured by speckle tracking echocardiography, which may explain in part the clinical benefits found in clinical trials.

Outcome implication of sex-related effective orifice area normalized to body size in aortic stenosis.

INTRODUCTION: Although several echocardiographic parameters have different values according to sex, there are no studies in echocardiographic variables of aortic stenosis (AS) severity. Our aim was to evaluate the sex-related prognosis of several echocardiographic parameters in AS. METHODS: Two hundred and twenty-five patients with at least moderate AS (effective orifice area [EOA] ≤ 1.50 cm2 ) were prospectively enrolled. EOA was normalized to body surface area (BSA), height, and body mass index (BMI). Receiver operating characteristic curves, in women and men separately, were plotted to determine the best cutoff value for predicting cardiovascular death. RESULTS: The largest area under the curve (AUC) to predict cardiovascular death was EOA in men (AUC 0.74, P < .001) and EOA/height in women (AUC 0.81, P < .001). An EOA/height cutoff value of 0.55 cm2 /m in women had a sensitivity of 100% and specificity of 61%; a cutoff of 0.50 cm2 /m in men obtained a sensitivity of 92% and a specificity of 56%. During a mean follow-up of 247 ± 183 days, there were 33 cardiovascular deaths. Women with EOA/height ≤ 0.55 cm2 /m had higher cardiovascular mortality (22% vs 0%, P < .001) and men with EOA/height ≤ 0.50 cm2 /m (21% vs 2%, P < .001). One-year survival in women with EOA/height ≤ 0.55 cm2 /m was 67 ± 8% and 100 ± 0% in EOA/height > 0.55 cm2 /m (P < .001). In men, 1-year survival was 70 ± 8% in EOA/height ≤ 0.50 cm2 /m, and 93 ± 6% in EOA/height > 0.50 cm2 /m (P = .004). CONCLUSIONS: Normalization of EOA is useful in AS, especially in women. We recommend using an EOA/height cutoff value of 0.55 cm2 /m in women, and 0.50 cm2 /m in men to identify a subgroup with higher cardiovascular risk.

Oral anticoagulation in chronic kidney disease with atrial fibrillation.

Chronic kidney disease (CKD) and atrial fibrillation (AF) frequently coexist, amplifying the risk of cardiovascular events and mortality. In patients with CKD stage 3 and non-valvular AF, direct oral anticoagulants (DOACs) have shown, compared to vitamin K antagonists (VKA), equal or greater efficacy in the prevention of stroke and systemic embolism, and greater safety. There are no randomizedtrials of the efficacy and safety of DOACs and VKA in advanced CKD. On the other hand, observational studies suggest that DOACs, compared to warfarin, are associated with a lower risk of acute kidney damage and generation/progression of CKD. This paper reviews the epidemiological and pathophysiological aspects of the CKD and AF association, the evidence of the efficacy and safety of warfarin and ACODs in various stages of CKD with AF as well as the comparison between warfarin and ACODs in efficacy and anticoagulant safety, and in its renal effects.

Update for 2014 on clinical cardiology, geriatric cardiology, and heart failure and transplantation.

In the present article, we review publications from the previous year in the following 3 areas: clinical cardiology, geriatric cardiology, and heart failure and transplantation. Among the new developments in clinical cardiology are several contributions from Spanish groups on tricuspid and aortic regurgitation, developments in atrial fibrillation, syncope, and the clinical characteristics of heart disease, as well as various studies on familial heart disease and chronic ischemic heart disease. In geriatric cardiology, the most relevant studies published in 2014 involve heart failure, degenerative aortic stenosis, and data on atrial fibrillation in the geriatric population. In heart failure and transplantation, the most noteworthy developments concern the importance of multidisciplinary units and patients with preserved systolic function. Other notable publications were those related to iron deficiency, new drugs, and new devices and biomarkers. Finally, we review studies on acute heart failure and transplantation, such as inotropic drugs and ventricular assist devices.

Anticoagulación oral en la enfermedad renal crónica con fibrilación auricular / Oral anticoagulation in chronic kidney disease with atrial fibrillation

La enfermedad renal crónica (ERC) y la fibrilación auricular (FA) frecuentemente coexisten, amplificando el riesgo de eventos cardiovasculares y de mortalidad. En pacientes con ERC estadio 3 y FA no valvular los anticoagulantes orales de acción directa (ACOD) han demostrado, comparados con antagonistas de la vitamina K (AVK), igual o superior eficacia en la prevención de ictus y embolismo sistémico, y mayor seguridad. No existen ensayos aleatorizados de la eficacia y la seguridad de ACOD y AVK en la ERC avanzada. Por otra parte, estudios observacionales sugieren que los ACOD, comparados con warfarina, se asocian a menor riesgo de daño renal agudo y de generación/progresión de la ERC. En este trabajo se revisan los aspectos epidemiológicos y fisiopatológicos de la asociación ERC y FA, las evidencias de la eficacia y seguridad de la warfarina y de los ACOD en las diversas fases de la ERC con FA, así como la comparación entre warfarina y ACOD en la eficacia y seguridad anticoagulante, y en sus efectos renales
