Pulmonary hypertension: the state of the art

Pulmonary hypertension (PH) is a hemodynamic and pathophysiological condition defined as an increase in mean pulmonary arterial pressure of 25 mmHg or more at rest assessed by right heart catheterisation. It is a progressive disease characterized by high mortality and morbidity. Current PH guidelines suggest that patients with PH should be cared for in dedicated specialist centres, with expertise and resources available to provide high quality care to this fragile population. In this review, we focus on the clinical manifestations, diagnostic algorithm, risk assessment and therapeutic strategies for PH. We also provide an overview of the organisation of PH services in United Kingdom, including designation of expert centres, national audit and steps to ensure the quality and financial viability of PH care

Post-traumatic myocardial infarction with hemorrhage and microvascular damage in a child with myocardial bridge: is coronary anatomy actor or bystander?

We present the case of a 13 year old patient with myocardial bridge in left anterior descending coronary artery, who develops a myocardial infarction after a cardiothoracic trauma. About 24 hours after admission for trauma, an Electrocardiogram (ECG) showed an ST-segment elevation on anterior-lateral leads and QS complex referable to anterior-septal infarction, and an increase in troponin T serum levels was noted. An impaired left ventricular ejection fraction with diffuse regional wall motion abnormalities involving the left ventricular apex and interventricular septum were seen at transthoracic echocardiography. Contrast enhanced cardiac magnetic resonance showed a widespread myocardial edema and necrosis at the level of left ventricular apex and interventricular septum. Intramural hemorrhage and signs of microvascular damage were found mainly at the mid-ventricular level of the anteroseptal and anterior segments of myocardium. The coronary angiography revealed normal coronary arteries except for a myocardial bridge on distal part of left anterior descending coronary artery. A myocardial infarction with hemorrhage and microvascular damage was diagnosed, but the absence of a correspondence between site of the most severe myocardial injury and distal location of myocardial bridge was noted. Whether myocardial infarction and microvascular damage have been caused only by traumatic hit, or also by the contribution of myocardial bridge, is unknown. An intense constriction of left anterior descending coronary artery at the level of myocardial bridge could have determined thrombus formation with subsequent septal and distal embolization and myocardial infarction

IL TRATTAMENTO DELLE DISLIPIDEMIE NELLA PREVENZIONE PRIMARIA DELLE MALATTIE CARDIOVASCOLARI: LE INDICAZIONI PER LA PRATICA CLINICA

Le dislipidemie rappresentano uno dei più importanti fattori causali della arteriosclerosi e delle sue complicanze d’organo, come l’infarto del miocardico, l’ictus e la vasculopatia periferica. Il loro appropriato trattamento rappresenta la base degli interventi di prevenzione primaria delle malattie cardiovascolari su base ischemica. In generale, per dislipidemia si intende una condizione clinica nella quale sono presenti alterazioni qualitative e/o quantitative dei lipidi e delle lipoproteine plasmatiche
