The association between VEGFR-TKI-induced hypertension and heart failure with preserved left ventricular ejection fraction (LVEF) (HFpEF) has been previously studied. Therefore, we investigated the relationship between hypertension onset and associated cardiac diastolic dysfunction due to VEGFR-TKI use. Patients who used VEGFR-TKIs (target drugs: sunitinib, axitinib, sorafenib, pazopanib, and cabozantinib) at the Department of Urology, Hokkaido Cancer Center were recruited between May 2009 and October 2021 and were divided into two groups based on whether their blood pressure was elevated during VEGFR-TKI use. The markers of left ventricular diastolic function (E/A, Dct (ms), mean E/e, septal e') and left ventricular systolic function (LVEF, LVDd, and LVDs) were evaluated. LVEF and mean E/e in the elevated blood pressure group (n = 41) showed significant changes before and after treatment. LVEF values (contractile function markers) in the TKI-HT (+) group significantly decreased from 70.7% ± 6.8% before treatment to 68.3% ± 7.8% after treatment (p = 0.03). Conversely, no significant difference was observed for any ventricular systolic function marker in the TKI-HT (−) group. E/e (diastolic function marker) in the TKI-HT (+) group significantly decreased from 11.9% ± 3.6% before treatment to 10.3% ± 3.0% after treatment (p = 0.02). However, no change was observed in any ventricular diastolic function marker in the TKI-HT (−) group. The results of this study suggest that cardiac function may be affected in patients using VEGFR-TKI. Furthermore, appropriate antihypertensive treatment and early monitoring with regular echocardiography, even in asymptomatic patients, may help prevent VEGFR-TKI-induced deterioration of systolic and diastolic function.展开更多

The advancement of novel treatment and their endorsement by international medical and scientific societies have shifted the treatment of HF with reduced ejection fraction (HFrEF) towards quadruple therapy: an angiotensin receptor-neprilysin inhibitor or an angiotensin-converting enzyme inhibitor, a beta-blocker, a mineralocorticoid receptor antagonist and a sodium/glucose co-transporter-2 inhibitor (SGLT2i). This paper reviews the available literature on state-of-the-art diagnostic and therapeutic advances in HFrEF, discusses landmark trials that shifted the paradigm towards quadruple therapy in HFrEF, visits the potential challenges in Lebanon and globally, proposes an algorithm for treatment introduction and sequencing in HFrEF and highlights clinical considerations for HFrEF management and patient education and follow-up. This practical guidance could serve cardiologists and other medical specialists in identifying clinical signs of HFrEF, diagnosing patients, referring them or prescribing the components of quadruple therapy, and offering medical advice and follow-up. We highlight the role of SGLT2is in HF management and their effectiveness in reducing rates of hospitalization for HF as well as cardiovascular deaths, with satisfactory safety profile.展开更多
