Screening and treatment intervention for insulin resistance/hyperinsulinemia hoping to prevent heart failure or slow its worsening.

Heart failure (HF) is the common endpoint of most heart diseases, affecting between 1 and 3% of the adult population worldwide, but increases to approximately 10% in adults over 70 years of age, exceeding 20% in those over 80-85 years of age [1, 2].

HF is the leading cause of hospital admissions in Italy and in most of developed and developing countries, accounting for approximately 2% of total hospital admissions, with high rehospitalization rates and very high healthcare costs [2]. In recent years, cases of HFpEF have been increasing steadily, particularly in women, and have now exceeded 50% of HF cases. It is well known that HFrEF and HFpEF have completely different causes and pathophysiological mechanisms. Therefore, also therapies are different. In fact, while HFrEF has treatments well defined by guidelines, HFpEF has few useful drugs identified only in recent years (finerenone, SGLT-2 Is, GLP-1 Ras) [3]. Important recognized causes of HF, particularly HFpEF, are cardiometabolic diseases. Among these, very prevalent in the general population worldwide is insulin resistance with associated hyperinsulinemia [4, 5]. It is the principal cause of type 2 diabetes, preceding its development by many years – even 15 or more [6, 7]. In the meantime, hyperinsulinemia produces significant damage to the cardiovascular system, to the extent that individuals with type 2 diabetes are treated, according to guidelines, as they had already experienced a cardiovascular event [8]. It has been shown that hyperinsulinemia of insulin resistance is also associated with concentric remodeling of left ventricle and diastolic dysfunction, main features of HFpEF  [9] . Therefore, in the hope of reducing hospitalizations, deaths, and healthcare costs resulting from HF, we believe that would be extremely important to implement a more thorough cardiovascular disease prevention plan, particularly by intervening early in the recognition and treatment of insulin resistance in the general population, and finding treatments that more effectively could block or slow the worsening progression of HF.
