Aims: Cardiac involvement as myocarditis and/or pericarditis is now recognized as a rare but possible adverse event following SARS-CoV-2 mRNA vaccines. In this brief report we describe a series of four subjects: three of them with myocarditis and one with pericarditis probably due to hypersensitivity and developed in temporal association with COVID-19 mRNA vaccination. Methods and results: During last summer, we observed a series of four young Caucasian male [median (range) age, 25 (18–32) years] presenting to the Emergency Department with severe acute chest pain within few days after second dose COVID-19 mRNA vaccine administration [median (range), 3 (2–5) days]. All of these were previously healthy and fitness males. All patients had abnormal electrocardiogram (EKG) and three of them had elevated high sensitive cardiac I troponin (hs-cTnI) levels. These latter three were diagnosed as having myocarditis and undergone cardiac magnetic resonance imaging (CMR). None had acute or prior COVID-19 or pulmonary disease on chest X-ray. Moreover, ischaemic injury, other infections, adverse drug reactions or any autoimmune diseases were excluded by appropriate tests. All patients underwent ecocardiography which showed preserved ejection fraction and no wall motion abnormalities and it excluded coronary origin abnormalities in each patient. The hospital course was uneventful for all four patients and they were discharged within few days of hospitalization [median (range), 6 (3–8) days] after a conservative treatment. The four patients met CDC criteria for probable myocarditis and pericarditis. To date, it is recognized a possible clinical correlation between cardiac injury and SARS-CoV-2 mRNA vaccination. The following elements support this hypothesis: (i) short time lapse between vaccine administration and symptoms onset; (ii) onset after the second dose suggesting an immune-mediated pathogenesis needing a previous sensibilization; (iii) exclusion of other possible damage causes (ischaemia, infections, other immune-mediated diseases, toxicity). In particular, we did not perform coronary angiography given the low pre-test probability of coronary heart disease. Although compending a small sample, our report includes a patient series with clinical features similar to those frequently encountered into other papers: i.e. a prevalence in young males without risk factors; symptoms onset within few days second dose administration; an eventful clinical course. This benign course, seen in the majority of cases in literature, raises the question of the need for specific therapy or an empirical one for symptoms control only. Our report suggest that possible cardiac involvement can range from isolated pericarditis to myocarditis with significant hs-cTnI raise and signs of acute inflammation at CMR or even a myocardial injury with a mild hs-cTnI raise in absence of pathological signs at CMR. This latter case suggests also a possible cardiac injury with subclinical course. Conclusions: To date, we are observing a temporal association linking mRNA SARS-CoV-2 vaccines administration and cardiac involvement. According to the majority of papers, our experience suggests an acute benign course of such cardiac involvement; a longer follow-up will also reveal a long-term benign course or conversely the presence of any sequelae. Clinicians should adequately inform patients when receiving vaccine to ensure prompt symptoms recognition and consequently put in place the best management of myocarditis/pericarditis. Finally, it is important to keep in mind that the benefits of vaccines far outweigh the risks.

Background/Introduction: An increasing number of elderly patients are subjected to Cardiac resynchronization therapy (CRT) to improve symptoms of heart failure (HF).

Objectives: The aim of this prospective study was to evaluate muscle force of the hand, thumb, and forefinger in patients with prolonged radial occlusion after transradial percutaneous coronary procedures. Background: There are no data on hand strength and function in patients with prolonged radial occlusion after percutaneous coronary procedures. Methods: Elective patients with chronic stable angina undergoing percutaneous coronary procedures were evaluated the day before the procedure for radial artery patency, Allen test, hand grip, and thumb and forefinger pinch tests. The same measures were performed the day after the procedure and at follow‐up. At follow‐up, patients were divided in two groups according to the radial patency (group 1) or occlusion (group 2). Results: Of the 99 patients included in the study, 90 patients had a patent radial artery (group 1), and nine (9.1%) patients had an occluded artery (group 2). At baseline, there were no significant differences in hand grip test between the two groups (42 ± 11 kg in group 1 and 41 ± 17 kg in group 2, P = 0.74). In both groups, after the procedure, the hand grip test values was significantly reduced compared with baseline values (40 ± 11 kg in group 1, P < 0.0001 and 37 ± 17 kg in group 2, P = 0.007). Finally, at follow‐up, in both groups, the hand grip test values returned to baseline values. Thumb and forefinger pinch tests did not show significant differences after the procedure and at follow‐up, compared with baseline. Conclusions: Radial artery occlusion after percutaneous coronary procedures was not associated with a reduction in hand and finger strength.

Author Summary: Background.: Anthracyclines and taxanes are effective drugs in breast cancer (BC), but their toxicity profiles limit their use in combination. A dose-finding study was performed to determine maximum tolerated doses (MTDs) of nonpegylated liposomal doxorubicin (TLC-D99) and docetaxel (DTX) as a dose-dense schedule, to maintain dose intensity, and to limit toxicity, particularly cardiac. Methods.: Twenty-four patients were enrolled, 12 with metastatic BC, 5 with locally advanced BC, and 7 with early BC. An intra- and interpatient approach was planned in two sequential steps. In the first step, TLC-D99 was administered at dose levels of 40, 45, and 50 mg/m2 plus DTX at a fixed dose of 50 mg/m2. In the second step, TLC-D99 was administered at the dose established in the first step plus DTX at dose levels of 55, 60, and 65 mg/m2. Every treatment cycle was delivered on day 1 every 14 days. Pegylated granulocyte colony-stimulating factor was scheduled on day 2. Dose-limiting toxicities (DLTs) were defined as G4 hematological; G3 nonhematological; ≥10% or ≥20% left ventricular ejection fraction (LVEF) reduction if the final value was <50% or ≥50%, respectively; severe arrhythmia; and symptomatic heart failure. LVEF was evaluated by echocardiography every two cycles, and precursor brain natriuretic peptide (pBNP) and cardiac troponin I (cTnI) were monitored on days 1 and 2. Results.: Five DLTs occurred (20.8%). No cardiac event of congestive heart failure was reported; 2 events of grade 3 cardiac dysfunction (8.3%), including a ≥20% LVEF reduction in 1 patient and symptomatic arrhythmia in another; 2 incidences of G4 neutropenia (8.3%); and 1 occurrence of G3 asthenia (4.2%) were reported. MTDs were not reached. The recommended doses were established as TLC-D99 50 mg/m2 and DTX 65 mg/m2. Cumulatively, mild (G1–G2) cardiac dysfunction was observed in 58.4% of patients: G1 cardiac arrhythmia was noted in 50%, G1–G2 general cardiac toxicity occurred in 25%, and concomitant toxicity was present in 17%. cTnI never increased. pBNP was increased in 25% and was associated with limiting arrhythmia in 4% and cardiac dysfunction in 16%. Conclusion.: Dose-dense TLC-D99 50 mg/m2 and DTX 65 mg/m2 can be safely administered in combination every 2 weeks for breast cancer, with the highest projected dose intensity for each drug at 25 and 32.5 mg/m2 per week, respectively.

The aim of this study was to evaluate 17-year actual clinical outcomes of patients undergoing coronary artery bypass graft (CABG) using skeletonized versus pedicled bilateral internal mammary arteries (BIMAs). From September 1991 to June 1996, 548 consecutive patients underwent CABG for multivessel disease using BIMA. After propensity matching, 350 patients were enrolled: 175 patients with skeletonized BIMA (Group S) and 175 with pedicled BIMA (Group P). The two groups were adequately comparable. Composite end-point: deaths, new revascularization and new myocardial infarctions were defined as ‘events’. Group S provided a higher rate of total arterial myocardial revascularization (94.3 vs 82.9%, P 0.001) with a higher average number of arterial anastomoses (3.1 ± 0.8 vs 2.7 ± 0.8, P < 0.001) and BIMA anastomoses (2.5 ± 0.3 vs 2.1 ± 0.3, P < 0.001). In Group S, the incidence of sequential grafts was higher (37.7 vs 17.7%, P < 0.001). The rate of sternal wound healing problems was lower (1.7 vs 7.4%, P = 0.010). Thirty-day mortality and morbidity were similar. The median survival time of survivors was 17.8 years (min–max = 17.0–21.5); 17.3 (17.0–18.0) in Group S vs 19.1 (18.1–21.5) in Group P, P < 0.001. Seventeen-year actual outcomes were better in Group S: deaths (8.7 vs 27.9%, P < 0.001), cardiac deaths (4.7 vs 13.4%, P = 0.005), cardiac events (10.5 vs 22.1%, P = 0.003), new revascularization (2.9 vs 8.7%, P = 0.021) and events (15.1 vs 36.1%, P < 0.001). Skeletonization of BIMA allows one to achieve a higher rate of arterial grafting and better outcome if compared with pedicled BIMA.

Left ventricular surgical remodelling (LVSR) can be targeted to volume reduction (VR), (independently of the final shape) or to conical shape (CS). The aim of this study was to evaluate the long-term clinical and echocardiographic results of these two surgical strategies. From January 1988 to December 2012, 401 patients underwent LVSR: 107 in Group VR (1988–2001) and 294 in Group CS (1998–2012). The latter group of patients had lower ejection fraction (EF) and higher mitral and tricuspid regurgitation grade, with higher incidence of pulmonary hypertension. A propensity score model was built to adjust long-term results for preoperative and operative profiles. Thirty-day mortality was 6.0%. Median follow-up interval time was 100 (3–300) months. Overall 20-year and event-free survival were 36.1 ± 7.8 and 19.4 ± 7.2, respectively. No differences were found regarding 10-year survival (Group VR: 55.1 ± 4.8 vs Group CS: 64.2 ± 4.2, P = 0.16) and event-free survival (Group VR: 41.1 ± 4.8 vs Group CS: 50.5 ± 4.8, P = 0.12). However, Group CS provided better 10-year freedom from cardiac deaths (74.5 ± 3.7 vs 60.4 ± 4.8, P = 0.03) and from cardiac events (55.6 ± 5.0 vs 45.0 ± 4.9, P = 0.04). After propensity score adjustment, all the main outcomes were significantly better in Group CS. Multivariate Cox analysis confirmed this result; furthermore, to avoid any bias related to improved experience, 30-day mortality being higher in Group VR, we excluded the first month from Cox analysis: left ventricle VR (independently of the final shape) was still confirmed as the wrong approach. At the follow-up, Group CS showed significant improvement in EF (+18 vs +8%), end-systolic volume index (−35 vs −20%) and sphericity index (−6 vs +9%). LVSR should aim to provide a more physiological shape (conical) rather than simple VR.
