Pulmonary hypertension (PH) is a common and severe complication of heart failure (HF). Consequently, HF is the leading cause of PH. For many years, specialists have attempted to better understand the pathophysiology of PH in HF, to define its prevalence and its impact on prognosis in order to improve the therapeutic management of these patients. Nowadays, despite the recent guidelines published on the subject, several points remain unclear or debated, and until now, no study has demonstrated the efficacy of any treatment. The aim of this review is to report the evolution of the concepts on post‐capillary PH (diagnosis, prevalence, prognosis, and therapeutics). The main issues are raised, focusing especially on the link between structural alterations and haemodynamic abnormalities, to discuss the possible reasons for treatment failures and future potential targets.

Among toxicities associated with molecular targeted agents (MTA), cardiovascular toxicities remain largely unknown or underestimated. Their frequency is variable and dependent on the compound. A high incidence of hypertension, symptomatic or asymptomatic left ventricular systolic dysfunction, acute coronary syndrome, arterial and venous thrombosis has been observed in patients receiving MTA. One of the most threatening complications of angiogenic inhibitors (AI) could be QT prolongation with the risk of torsade de pointes (TdP) and sudden death. QT prolongation and torsade de pointes accounted for 29% of cardiac and non-cardiac post-marketing withdrawals. The assessment of the effects of drugs on cardiac repolarization is the subject of recent guidelines and recommendations. Regulatory agencies now require practically every new pharmaceutical compound to undergo a thorough investigation of its propensity to modify cardiac repolarization. To reduce the incidence of QT prolongation and torsade de pointes in patients receiving AI, cancer patients should be closely monitored while receiving AI.

High vWF plasma concentrations may discriminate patients with NVAF at greater risk of stroke or all-cause death.

Emergency departments, ambulances and general practitioners are the main points of entry before hospitalization for acute/worsening heart failure. Home discharge occurs in two of three cases. Time to first patient post-discharge visit is delayed. Therefore, actions to improve the patient journey should target primary care physicians and emergency structures, and efforts should be made to reduce the time to the first visit after discharge.
