does smoking cause pulmonary hypertension

Smoking can potentially cause pulmonary arterial hypertension due to the detrimental long-term impact of harmful chemicals released from tobacco combustion on the pulmonary vasculature.

Initially, smoking incites an inflammatory response in the lungs, potentially leading to damage and constriction of the pulmonary arterioles. As these arterioles constrict, the resistance to blood flow escalates, which in turn raises the pulmonary artery pressure. Additionally, nicotine in tobacco can stimulate the release of adrenaline, leading to a temporary increase in blood pressure and heart rate, which may indirectly affect the pulmonary arteries. Furthermore, chronic smoking may result in conditions such as emphysema and chronic obstructive pulmonary disease (COPD), both of which can contribute to increased pulmonary artery pressure.

To prevent pulmonary arterial hypertension, it is imperative to quit smoking. Moreover, if symptoms like shortness of breath, chest pain, or syncope arise, one should seek medical attention immediately and follow the prescribed treatment under a physician's supervision. Compliance with medical instructions is essential during treatment and self-medication should be avoided.
