I30-I52: Other forms of heart disease

I50: Heart failure

Heart failure, a condition that falls under the ICD-10 group range of I50, refers to a complex clinical syndrome where the heart is unable to pump sufficient blood to meet the body's requirements. This inability may be the result of functional or structural impairments of the heart. Heart failure can progress slowly over time or it can develop suddenly, depending on underlying causes such as heart disease, high blood pressure, or diabetes. Symptoms commonly include fatigue, breathlessness, and swelling in the legs, ankles, feet or abdomen. Given that heart failure affects the circulatory system, it can impact multiple organ systems and overall bodily function. The course of the disease is often unpredictable, varying greatly among individuals based on factors such as the severity of the condition, age, and existing comorbidities. It should be noted that heart failure does not mean that the heart has stopped working, but rather that it cannot work as efficiently as it should.
