Resumen


Resumen

La miocardiopatía diabética (MCD) es una complicación de la diabetes mellitus tipo 2 (DM2) que es capaz de evolucionar hasta desarrollar insuficiencia cardiaca (IC) sintomática, independientemente de los factores de riesgo tradicionales para esta, como la enfermedad de las arterias coronarias y la hipertensión. No hay un tratamiento específico para la MCD; sin embargo, los inhibidores del cotransportador sodio-glucosa tipo 2 (iSGLT2) son fármacos hipoglucemiantes que actúan en los canales SGLT2 e inhiben la reabsorción de glucosa en el riñón; además, tienen efectos cardioprotectores, por lo que sus mecanismos a nivel cardiaco se han estudiado. De acuerdo con resultados de estudios preclínicos, los iSGLT2 actúan al interferir en la fisiopatología de la MCD. Sus principales efectos son: mejoramiento en la función diastólica y la fracción de eyección del ventrículo izquierdo (FEVI), atenuación en el progreso de la fibrosis cardiaca, reducción del estrés oxidativo y marcadores proinflamatorios. Los ensayos clínicos en humanos que se han realizado específicamente con MCD son limitados; no obstante, ensayos clínicos aleatorizados en pacientes portadores de IC han evidenciado beneficios con iSGLT2, independientemente del control glucémico en la reducción de hospitalización por IC y mortalidad por causas cardiovasculares. Resumiendo, los iSGLT2 nos sugieren un tratamiento en la MCD por sus beneficios cardiovasculares, en modelos preclínicos y clínicos de MCD y en el control glucémico de la DM2.

 

Abstract

Diabetic cardiomyopathy (DCM) is a complication of type 2 diabetes mellitus (T2DM) capable of progressing to the development of symptomatic heart failure (HF), independently of traditional risk factors for it, such as coronary artery disease and hypertension. There is no specific treatment for DCM; however, sodium-glucose cotransporter 2 inhibitors (SGLT2i) are hypoglycemic drugs that act on SGLT2 channels, inhibiting glucose reabsorption in the kidney. In addition, they have cardioprotective effects, which is why their mechanisms at the cardiac level have been studied. According to the results of preclinical studies, SGLT2i act by interfering in the pathophysiology of DCM. Their main effects are: improvement in diastolic function and left ventricular ejection fraction (LVEF), attenuation in the progress of cardiac fibrosis, reduction of oxidative stress and proinflammatory markers. The clinical trials in humans specifically with DCM that have been carried out are limited; however, randomized clinical trials in patients with HF have shown benefits with SGLT2i, regardless of glycemic control in the reduction of hospitalization for HF and mortality from cardiovascular causes. In summary, SGLT2i suggest a treatment in DCM due to their cardiovascular benefits, in preclinical and clinical models of DCM and in the glycemic control of T2DM.
