pulmonary hypertension due to left ventricular diastolic dysfunction icd-10

Pulmonary arterial hypertension (PAH) is a cardiovascular condition stemming from left ventricular diastolic dysfunction. This form of PAH is commonly linked to heart failure, particularly when the left ventricle fails to relax and fill adequately, resulting in elevated back pressure in the pulmonary circulation.

Left ventricular diastolic dysfunction can arise from a variety of causes, such as hypertension, coronary artery disease, valvular heart disease, diabetes, and aging. These factors may lead to myocardial fibrosis, thickening, or other structural alterations that impair the heart's ability to diastole. Over time, the pulmonary vasculature can also be compromised, with vessels becoming increasingly rigid and constricted, further exacerbating pulmonary arterial pressure. Untreated, this can progress to right ventricular hypertrophy, arrhythmias, and potentially heart failure.

For individuals with PAH due to left ventricular diastolic dysfunction, it is crucial to manage blood pressure, blood sugar, and lipid levels in daily life and to maintain a healthy lifestyle that includes regular exercise, smoking cessation, moderate alcohol consumption, and a balanced diet. Regular monitoring of cardiac function and pulmonary arterial pressure is essential, with treatment adjustments made under a physician's supervision. It is imperative not to alter medication dosages or discontinue medications without medical guidance to prevent disease progression.
