Epub 2019 Apr 10. PMID: 31030969.</p> <p> </p> <p>This is the abstract:</p> <p>Patients with a Fontan circulation are at risk of a sedentary lifestyle. Given the direct relationship between physical activity and health, promotion of physical activity has the potential to improve outcomes, including quality of life (QOL). This study aimed to describe self-reported physical activity levels in adult Fontan patients and examine associations between physical activity, perceived health status and QOL. The sample consisted of 177 Fontan patients (M<sub>age</sub> = 27.5 ± 7.6 years, 52% male) who reported their physical activity, perceived health status, and QOL as part of the cross-sectional Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease - International Study. Descriptive statistics and univariate analyses of variance with planned contrasts were computed to describe physical activity characteristics. Mediation analyses tested whether perceived health status variables mediated the association between physical activity and QOL. Forty-six percent of patients were sedentary while only 40% met international physical activity guidelines. Higher physical activity was associated with younger age, lower NYHA class, higher perceived general health, and greater QOL. Patients who commuted by walking and engaged in sports reported better perceived health and QOL. Mediation analyses revealed that perceived general health but not NYHA functional class mediated the association between physical activity and QOL (αβ = 0.22, 95% confidence interval = 0.04 to 0.49). In conclusion, Fontan patients likely benefit from regular physical activity, having both higher perceived general health and functional capacity; greater perceived health status may contribute to enhanced QOL. In conclusion, these data support the pivotal role of regular physical activity for Fontan patients.</p>

PMID: 31473325.</p> <p> </p> <p>This is the abstract:</p> <p>Limited evidence is available on 5-year clinical outcomes after percutaneous edge-to-edge mitral valve repair.</p> <p><strong>Methods: </strong>The Getting Reduction of mitrAl inSufficiency by Percutaneous clip implantation in ITaly (GRASP-IT) is a multicenter registry including 304 consecutive patients undergoing Mitraclip between October 2008 and October 2013 at 4 Italian centers. Primary end point (all-cause mortality) and secondary end point (all-cause mortality or heart failure [HF] hospitalization) were evaluated up to 5 years and between 1 and 5 years.</p> <p><strong>Results: </strong>Cumulative incidence of the primary and secondary end points at 1, 2, 3, 4, and 5 years were 15.1%, 26.4%, 35.5%, 42.1%, and 47.3% and 29.1%, 41.7%, 49.8%, 56%, and 62.3%, respectively. Landmark analysis between 1 and 5 years showed an incidence of primary and secondary end point of 37.9% and 46.8%, respectively. Five-year event rates were significantly higher in patients with functional ischemic mitral regurgitation (MR) compared to other etiologies. MR recurrence and left ventricular ejection fraction <30% were associated with an increased risk of both primary and secondary end points. EuroSCORE II >5% was associated with an increased risk of 5-year mortality. Ischemic etiology of MR, baseline serum creatinine >1.5 mg/dL, chronic obstructive pulmonary disease, and previous HF hospitalizations were independent predictors of 5-year secondary end point.</p> <p><strong>Conclusions: </strong>At 5-year follow-up after Mitraclip, nearly half of patients died and almost two thirds died or were admitted for HF. MR recurrence, ischemic etiology, high comorbidity burden (ie, EuroSCORE II >5%, chronic obstructive pulmonary disease), and advanced cardiomyopathy (ie, left ventricular ejection fraction <30%, prior HF admission, creatinine >1.5 mg/dL) significantly increase the relative risk of 5-year clinical events.</p>

PMID: 30970334.</p> <p> </p> <p>This is the abstract:</p> <p><strong>Objective: </strong> Indoor microclimate may affect students' wellbeing, cardiac autonomic control and cognitive performance with potential impact on learning capabilities. To assess the effects of classroom temperature variations on the autonomic profile and students' cognitive capabilities.</p> <p><strong>Approach: </strong> Twenty students attending Humanitas University School, (14M, age 21 ± 3 years) underwent a single-lead ECG continuous recording by a portable device during a 2 h lecture when classroom temperature was set 'neutral' (20 °C-22 °C, Day 1) and when classroom temperature was set to 24 °C-26 °C (Day 2). ECGs were sent by telemetry to a server for off-line analysis. Spectral analysis of RR variability provided indices of cardiac sympathetic (LF<sub>nu</sub>), vagal (HF, HF<sub>nu</sub>) and cardiac sympatho-vagal modulation (LF/HF). Symbolic analysis of RR variability provided the percentage of sequences of three heart periods with no significant change in RR interval (0V%) and with two significant variations (2V%) reflecting cardiac sympathetic and vagal modulation, respectively. Students' cognitive performance (memory, verbal comprehension and reasoning) was assessed at the end of each lecture using the Cambridge Brain Sciences cognitive evaluation tool.</p> <p><strong>Main results: </strong> Classroom temperature and CO<sub>2</sub> were assessed every 5 min. Classroom temperatures were 22.4 °C ± 0.1 °C (Day 1) and 26.2 °C ± 0.1 °C (Day 2). Student's thermal comfort was lower during Day 2 compared to Day 1. HR, LF/HF and 0V% were greater during Day 2 (79.5 ± 12.1 bpm, 6.9 ± 7.1 and 32.8% ± 10.3%) than during Day 1 (72.6 ± 10.8 bpm, 3.4 ± 3.7, 21.4% ± 9.2%). Conversely, 2V% was lower during Day 2 (23.1% ± 8.1%) than during Day 1 (32.3% ± 11.4%). Short-term memory, verbal ability and the overall cognitive C-score scores were lower during Day 2 (10.3 ± 0.3; 8.1 ± 1.2 and 10.9 ± 2.0) compared to Day 1 (11.7 ± 2.1; 10.7 ± 1.7 and 12.6 ± 1.8).</p> <p><strong>Significance: </strong> During Day 2, a shift of the cardiac autonomic control towards a sympathetic predominance was observed compared to Day 1, in the presence of greater thermal discomfort. Furthermore, during Day 2 reduced cognitive performances were found.</p>

PMID: 31774869; PMCID: PMC6881030.</p> <p>This is the article:</p> <p><strong>Background: </strong> Gender influences platelet biology. Women have a larger platelet count, but gender-based differences in platelet function remain debated. We performed a study addressing gender-based differences in platelet function using point-of-care platelet function tests (PFT).</p> <p><strong>Methods: </strong> The patient population consisted of 760 cardiac surgery patients where preoperative PFT (multiple-electrode aggregometry [MEA]) were available. Platelet count and function at the ADPtest and TRAPtest were compared in the overall population and separately in patients with or without residual effects of P2Y12 inhibitors.</p> <p><strong>Results: </strong> Women had a significantly (P = 0.001) higher platelet count but a non-significantly higher platelet reactivity to ADP. In clopidogrel-treated patients, the platelets ADP reactivity was significantly (P = 0.031) higher in women, and platelet count was the main determinant of platelet hyper-reactivity. Within patients under full clopidogrel effects, women with a platelet count ≥ 200,000 cells/μL had a significantly (P = 0.023) higher rate of high-on-treatment platelet reactivity (HTPR, 45.5%) with respect to males with a platelet count < 200,000 cells/μL (11.9%), with a relative risk of 6.2 (95% confidence interval 1.4-29).</p> <p><strong>Conclusions: </strong> Our findings confirm that women have a larger platelet count than men, and that this is associated to a trend towards a higher platelet reactivity. HTPR is largely represented in women with a high platelet count. This generates the hypothesis that women requiring P2Y12 inhibitors could potentially benefit from larger doses of drug or should be treated with anti-platelet agents with a low rate of HTPR.</p>

PMID: 31063482; PMCID: PMC6504093</p> <p> </p> <p>This is the abstract:</p> <p>Regular exercise is recommended to improve the cardiovascular risk profile. However, there is growing evidence that extreme volumes and intensity of long-term exertion may increase the risk of acute cardiac events. The aim of this study is to investigate the after-effects of regular, strenuous physical training on the cardiovascular neural regulation in a group of amateur triathletes compared to age-matched sedentary controls. We enrolled 11 non-elite triathletes (4 women, age 24±4 years), who had refrained from exercise for 72 hours, and 11 age-matched healthy non-athletes (3 women, age 25±2 years). Comprehensive echocardiographic and cardiopulmonary exercise tests were performed at baseline. Electrocardiogram, non-invasive blood pressure, respiratory activity, and muscle sympathetic nerve activity (MSNA) were continuously recorded in a supine position (REST) and during an incremental 15° step-wise head-up tilt test up to 75° (TILT). Blood samples were collected for determination of stress mediators. Autoregressive spectral analysis provided the indices of the cardiac sympathetic (LFRR) and vagal (HFRR) activity, the vascular sympathetic control (LFSAP), and the cardiac sympatho-vagal modulation (LF/HF). Compared to controls, triathletes were characterized by greater LFRR, LF/HF ratio, LFSAP, MSNA, and lower HFRR at REST and during TILT, i.e. greater overall cardiovascular sympathetic modulation together with lower cardiac vagal activity. Cortisol and adrenocorticotropic hormone concentrations were also higher in triathletes. In conclusion, triathletes were characterized by signs of sustained cardiovascular sympathetic overactivity. This might represent a risk factor for future cardiovascular events, given the known association between chronic excessive sympathetic activity and increased cardiovascular risk.</p>

However, the rate of reoperation is not negligible.</p> <p><strong>Methods: </strong>This single-center prospective study assessed the general outcome of Ross reoperation and patients' perceived quality of life compared with 2 control groups (Ross non-reoperation and mechanical aortic valve replacement). Patient's preference regarding the choice between mechanical aortic valve and Ross procedure was investigated in a subgroup that could theoretically have been directed to either of the 2 procedures.</p> <p><strong>Results: </strong>Between 2005 and 2017, 64 consecutive patients underwent reoperation after Ross. Median age was 31 years. Median freedom from reoperation after the Ross procedure was 136 months. An autograft reoperation was required in 49, and 25 had homograft failure. No in-hospital death was recorded. Mean follow-up was 77 months (range, 6-164 months). Quality of life was assessed with the 36-Item Short Form Health Survey questionnaire. The Ross reoperation group showed a lower score involving psychological concerns compared with the other groups. In the reoperated-on patients group, 52 had adequate aortic annulus dimensions to receive a prosthetic valve instead of a Ross procedure. When asked whether they would make the same choice, only 31% confirmed the preference.</p> <p><strong>Conclusions: </strong>Reoperations after Ross procedure have low mortality and morbidity. Long-term follow-up showed a high quality of life, even after reoperations. However, owing to psychological concerns after the redo operation, when choosing a Ross procedure, it is our duty to thoroughly explain to patients that a high level of disillusion is predictable in case of reoperations.</p>

The aberrant alternative splicing of insulin receptor (IR) gene and post-receptor signalling abnormalities have been associated with insulin resistance, however the precise molecular defects that cause metabolic dysfunctions are still unknown. Thus, the aims of this study were to investigate in DM skeletal muscle biopsies if beyond INSR missplicing, altered IR protein expression could play a role in insulin resistance and to verify if the lack of insulin pathway activation could contribute to skeletal muscle wasting. Our analysis showed that DM skeletal muscle exhibits a lower expression of the insulin receptor in type 1 fibers which can contribute to the defective activation of the insulin pathway. Moreover, the aberrant insulin signalling activation leads to a lower activation of mTOR and to an increase in MuRF1 and Atrogin-1/MAFbx expression, possible explaining DM skeletal muscle fiber atrophy. Taken together our data indicate that the defective insulin signalling activation can contribute to skeletal muscle features in DM patients and are probably linked to an aberrant specific-fiber type expression of the insulin receptor.</p>

PMID: 31611837; PMCID: PMC6776629.</p> <p> </p> <p>This is the abstract:</p> <p> </p> <p>Cardiac involvement is one of the most important manifestations of the multisystemic phenotype of patients affected by myotonic dystrophy (DM) and represents the second cause of premature death. Molecular mechanisms responsible for DM cardiac defects are still unclear; however, missplicing of the cardiac isoform of troponin T (<em>TNNT2</em>) and of the cardiac sodium channel (<em>SCN5A</em>) genes might contribute to the reduced myocardial function and conduction abnormalities seen in DM patients. Since, in DM skeletal muscle, the <em>TNNT2</em> gene shows the same aberrant splicing pattern observed in cardiac muscle, the principal aim of this work was to verify if the <em>TNNT2</em> aberrant fetal isoform expression could be secondary to myopathic changes or could reflect the DM cardiac phenotype. Analysis of alternative splicing of <em>TNNT2</em> and of several genes involved in DM pathology has been performed on muscle biopsies from patients affected by DM type 1 (DM1) or type 2 (DM2) with or without cardiac involvement. Our analysis shows that missplicing of muscle-specific genes is higher in DM1 and DM2 than in regenerating control muscles, indicating that these missplicing could be effectively important in DM skeletal muscle pathology. When considering the <em>TNNT2</em> gene, missplicing appears to be more evident in DM1 than in DM2 muscles since, in DM2, the <em>TNNT2</em> fetal isoform appears to be less expressed than the adult isoform. This evidence does not seem to be related to less severe muscle histopathological alterations that appear to be similar in DM1 and DM2 muscles. These results seem to indicate that the more severe <em>TNNT2</em> missplicing observed in DM1 could not be related only to myopathic changes but could reflect the more severe general phenotype compared to DM2, including cardiac problems that appear to be more severe and frequent in DM1 than in DM2 patients. Moreover, <em>TNNT2</em> missplicing significantly correlates with the QRS cardiac parameter in DM1 but not in DM2 patients, indicating that this splicing event has good potential to function as a biomarker of DM1 severity and it should be considered in pharmacological clinical trials to monitor the possible effects of different therapeutic approaches on skeletal muscle tissues.</p> <p><strong>Keywords: </strong> alternative splicing; cardiac involvement; cardiac troponin T; myotonic dystrophies; skeletal muscle.</p>

J Cardiovasc Med (Hagerstown). 2019 Aug;20(8):557-563. doi: 10.2459/JCM.0000000000000799. PMID: 30950984.</p> <p> </p> <p>This is the abstract:</p> <p><strong>Aim: </strong> To report our experience about hypogastric artery coverage during endovascular aneurysm repair (EVAR) for aortoiliac aneurysms in patients younger than 80 years (group A) compared with octogenarian patients (group B).</p> <p><strong>Methods: </strong> Data of consecutive EVAR with hypogastric artery coverage from 01/1998 to 12/2016 were retrospectively analyzed. Primary outcomes were the occurrence of ischemic colitis, type II endoleak and buttock claudication both at 30 days and in the long term. P values less than 0.05 were considered statistically significant.</p> <p><strong>Results: </strong> The hypogastric artery was covered in 107 patients. Twenty-three (21.5%) were octogenarian (group B). At 30 days, one type II endoleak occurred in group B, whereas 16 patients of group A experienced buttock claudication. There were no cases of ischemic colitis. During follow-up (median 63.5 months), no cases of ischemic colitis occurred. Six new type II endoleaks were recorded (five in group B and one in group A, P = 0.0001). Buttock claudication persisted in four patients of group A. No new cases of buttock claudication were observed.</p> <p><strong>Conclusion: </strong> Unilateral hypogastric artery coverage during EVAR for aortoiliac aneurysms can be performed with an acceptable rate of postoperative complication. Postoperative buttock claudication was more frequent in younger patients, whereas a type II endoleak occurred mostly in octogenarian patients during follow-up.</p>
