Also consider pulmonary hypertension in case of unexplained shortness of breath!

Unexplained breathlessness is a frequent and challenging problem in the daily practice of general practitioners, pulmonologists and cardiologists. One possible underlying clinical picture is pulmonary hypertension (PH), which is often diagnosed far too late. It can occur without an identifiable cause, in conjunction with common heart and lung diseases such as chronic heart failure and chronic obstructive pulmonary disease or in conjunction with chronic thromboembolic disease [1]. Diagnosis of this complex disease is often delayed due to non-specific symptoms – a multidisciplinary approach is crucial for early detection and treatment [2].
