Article Synopsis
- Fractional flow reserve (FFR) is a standard method for assessing heart issues, but its use is limited due to time, cost, and discomfort associated with the procedure.
- A new method called saline-induced Pd/Pa ratio (SPR) may offer a simpler alternative to FFR, yet its clinical significance is still uncertain.
- The study found that SPR had a stronger correlation with FFR compared to resting full-cycle ratio (RFR) and showed superior diagnostic accuracy, suggesting SPR could effectively evaluate coronary artery stenosis.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease with obstructed airflow and frequently causes secondary mild-moderate pulmonary hypertension (PH). However, a low proportion (1%-5%) of COPD patients develop severe therapy-resistant PH, and it is crucial to determine whether the patient has another disease capable of causing severe PH, including pulmonary arterial hypertension.Here, we describe a case of a 71-year-old male with COPD complicated by severe PH and right heart failure.
