Novel Imaging Techniques for Heart Failure

Heart failure (HF) is an epidemic with an increasing prevalence and an absolute mortality rate of approximately 50 % within 5 years of diagnosis. Imaging plays a main role in HF diagnosis, assessment of aetiology and treatment guidance. This article reviews current HF applications for all the available non-invasive imaging modalities: echocardiography, cardiovascular magnetic resonance (CMR), nuclear imaging-positron emission tomography (PET) and single-photon emission computed tomography (SPECT) and computed tomography (CT).

A Practical Clinical Approach to the Diagnosis and Treatment of Patients with Pulmonary Hypertension

Pulmonary hypertension (PH) is said to occur when the mean pulmonary arterial pressure (mPAP) exceeds 25 mmHg at rest or 30 mmHg during exercise. There are many diverse causes of this condition but the term pulmonary arterial hypertension (PAH) is used to describe a rare group of diseases that share histopathological similarities in the small muscularised pulmonary arterioles leading to vascular remodelling known as plexogenic pulmonary arteriopathy (PPA).
