Pulmonary Arterial Hypertension Mild Symptoms

Pulmonary arterial hypertension (PAH) can often go unnoticed in its early stages. Some patients may not experience any symptoms at rest and only feel shortness of breath or chest tightness during physical activity. In certain cases, the first sign might be a noticeable decrease in exercise tolerance. For example, someone who previously could climb several flights of stairs without difficulty may begin to feel breathless or uncomfortable after just one or two flights, signaling a potential change in their cardiovascular health.

Understanding Mild PAH

When patients visit a medical facility, a right heart catheterization often reveals pulmonary artery pressure ranging between 25-35mmHg, which is indicative of mild pulmonary arterial hypertension. It is important to note that even mild PAH can progress over time. In some cases, the condition may rapidly advance to moderate or even severe stages, leading to increasingly pronounced symptoms that can significantly impact daily life.

Common Causes and Risk Factors

Many patients diagnosed with PAH have a history of conditions that contribute to elevated pulmonary artery pressure. A prior episode of pulmonary embolism—where blood clots block arteries in the lungs—can lead to secondary pulmonary hypertension. Additionally, individuals with congenital heart defects may experience increased pressure in the pulmonary arteries due to abnormal blood flow between the heart chambers. These underlying issues highlight the importance of identifying the root cause of PAH as early as possible.

Why Early Diagnosis Matters

Even mild symptoms of pulmonary arterial hypertension should not be ignored. Seeking care at a reputable medical center is crucial, as early diagnosis and treatment can significantly affect the progression of the disease. Identifying the underlying cause—whether it's related to previous lung issues, heart defects, or other factors—can allow for timely intervention. Proper management at an early stage may help prevent complications and improve long-term outcomes for patients with PAH.
