Isolated systolic hypertension is associated with higher risk of cardiovascular disease and all-cause mortality. Despite being the most common form of hypertension in the elderly, it is also detectable among young and middle-aged subjects. ⋯ Excess salt intake, often interacting with overweight and insulin resistance, may contribute to the development and maintenance of isolated systolic hypertension in young individuals by causing endothelial dysfunction and promoting arterial stiffness through a number of mechanisms, namely increase in the renin-angiotensin-aldosterone system activity, sympathetic tone and salt-sensitivity. This short review focused on the epidemiological and clinical evidence, the mechanistic pathways and the cluster of pathophysiological factors whereby excess salt intake may favor the development and maintenance of isolated systolic hypertension in young people.

Psoriasis is a chronic immune-mediated inflammatory disease characterized by erythematous plaques that can extend along the entire skin surface. In the latest years, it has been shown that serum calprotectin correlated strongly with several inflammatory biomarkers. Since high levels of calprotectin have been found in psoriatic lesions, it is of paramount importance to investigate the role of serum calprotectin as a possible novel diagnostic marker of psoriasis. Aim of our prospective pilot study was to assess the level of serum calprotectin in psoriatic patients. ⋯ In this pilot study psoriatic patients had a significant high level of serum calprotectin than healthy subjects, and this biomarker had high accuracy in identifying patients. Further studies, with larger sample size will need to confirm our data.

Coronary microvascular dysfunction (CMD) may cause symptoms of myocardial ischemia (microvascular angina [MVA]), but recent studies suggested that it might also contribute to the syndrome of heart failure with preserved ejection fraction (HFpEF). In this study we assessed the relation of CMD with findings of HFpEF in MVA patients. ⋯ Our data suggest that in patients with MVA there is no relation between the grade of impairment of coronary microvascular dilatation and findings of HFpEF.

Isolated systolic hypertension (ISH), defined as brachial systolic blood pressure (bSBP) ≥140 mmHg and diastolic blood pressure (DBP) <90 mmHg, is highly prevalent among young subjects and in the elderly. The prognostic significance of ISH in young individuals remains the object of large debate which might be solved, at least in part, if considering the prognostic role of central BP. For any given value of pBP, the cardiovascular (CV) risk is better defined by central BP (cBP). ⋯ As a result, different devices could provide different cBP values despite using the same biological signals. Devices providing accurate estimates of BP amplification as a dimensionless ratio between amplitudes of central and peripheral arterial waveforms might be well suited for clinical purposes in young individuals with ISH. There is urgent need of well-designed prospective studies aiming at longitudinally evaluating the amount of CV risk associated with elevated cBP in young subjects with ISH and their related incremental prognostic value.
