What is the Origin of Long-Term Cardiac Function?

The concept is a core element of longitudinal cardiovascular medicine and chronic disease management, focusing on outcomes that extend beyond acute events. In endocrinology, it gained prominence through studies investigating the chronic effects of sex steroid replacement, growth hormone, and thyroid hormone on the myocardium and vasculature. Understanding these prolonged effects guides safe prescribing practices.

What is the Mechanism of Long-Term Cardiac Function?

Hormones influence cardiac function through genomic and non-genomic pathways, affecting cardiomyocyte contractility, vascular remodeling, and lipid metabolism. For example, sustained imbalances in thyroid hormone or supraphysiological levels of certain growth factors can lead to adverse remodeling, such as ventricular hypertrophy or fibrosis, thereby compromising the heart's long-term pumping capacity and overall function.

Long-Term Cardiac Function

Meaning

Long-term cardiac function refers to the sustained efficiency and health of the heart muscle and vascular system over an extended period, often years or decades. Clinical assessment of this function includes metrics like ejection fraction, cardiac output, and the structural integrity of the ventricles and valves. This is a critical consideration in hormonal health, as many endocrine disorders and their treatments can have chronic, cumulative effects on cardiovascular health.
