Background While physical rehabilitation has been shown to be beneficial and safe for patients suffering from heart failure, data on rehabilitation for hypertrophic cardiomyopathy (HCM) patients are limited. Methods Forty-five HCM patients participated in an exercise rehabilitation program. Exercise capacity was measured in metabolic equivalent of task (METs) units and functional status was defined according to the New York Heart Association (NYHA). Self-reported measurements addressed the quality of life and daily life function. Results Of the 45 participants, 32 completed at least 3 months of rehabilitation and had data from two sequential exercise tests. A significant increase in exercise capacity (from mean 5.3 to 6.7 METs, p = 0.01), was achieved at higher peak heart rates. Eighteen patients (56%) who showed improvement in exercise capacity did not differ in their NYHA class, clinical, electrocardiographic, or echo-Doppler parameters compared to those who did not improve. The benefit from training was associated with a lower exercise capacity at baseline and was most pronounced in those capable of less than 6.8 METs (p = 0.008). No significant arrhythmias or adverse events were recorded in HCM patients during participation. In ∼40% of participants, training improved the subjective perception of functional capacity and quality of life; only 4 patients (9%) discontinued their participation due to discomfort during or following training. The improvement in exercise capacity was comparable between HCM and a reference group of dilated cardiomyopathy patients. Conclusions Exercise rehabilitation appears to be applicable and safe in HCM. It mainly benefits patients suffering from significant functional limitation. Larger prospective studies are needed to validate these findings and better characterize patients expected to benefit from these programs.

Vaccines against SARS-COV2 have been crucial in efforts against COVID19, yet there have been reports of pericarditis following vaccination with mRNA-based vaccines.We questioned consecutive patients with a history of acute pericarditis (AP) evaluated in the pericardial disease clinic during 3-11/2020 in a single tertiary center. Patients with significant myocardial involvement or pericarditis secondary to another systemic disease were excluded.We included 64 patients in the final analysis. Mean age was 53.1 (±18), and 26 (41%) were female. At least 1 recurrence of AP was documented in 47 (73%) cases, 32 (50%) had ≥ 3 recurrences prior to vaccination. AP was considered to be idiopathic\viral in 45 (70%) cases, 20 (31%) cases were post-injury. All patients received at least 2 doses of the vaccine, and 48 patients (75%) received a 3rd dose. Two cases of breakthrough COVID19 infections were documented. Overall, 12 patients (19%) reported any adverse events. Of which, 2 had recurrent pericarditis. There was a trend for a younger age in those patients who had adverse events (median age 45 [IQR 36-61] vs. 60 [38-71], p = 0.08). no other significant difference was seen.In patients with a history of acute\recurrent pericarditis, the use of BNT162b2 was mostly uneventful, but some mild disease recurrences did occur.

Idiopathic recurrent pericarditis (IRP) is a debilitating illness which leads to great suffering and multiple hospitalizations. Management of acute pericarditis and subsequent recurrences has evolved significantly as the use of colchicine-based strategies become more prevalent, yet there still remains a subset of patients who remain refractory to colchicine therapy, and these patients require prolonged corticosteroid (CS) therapy for the control of symptoms. Since the 1960s, there have been reports of successful management of these cases with immunosuppressive therapy. Current guidelines support the use of anakinra, intravenous immunoglobulins, and azathioprine for management of IRP, with the goals of both control of symptoms and withdrawal of CS. Recent reports supply evidence for both auto-inflammatory and autoimmune activity in these patients. We herein review the current available reports regarding the evidence regarding the pathophysiology and reported cases and case series of IRP cases managed with immunomodulation therapy.
