Abstract:Background: Previous studies of the Simon Broome (SB) FH register reported that, compared to the low-intensity statin period (1992-2008), the standardised cardiovascular disease (CVD) mortality ratio in the high-intensity statin period (2009-2015) was 22% lower in men but 115% higher in women. Linkage of the register with Hospital Episodes Statistics (HES) data has now enabled prospective evaluation of CVD morbidity based on inpatient care. Method(s): Standardised Morbidity Ratios (SMbR) compared to age and sex-matched UK primary care patients were calculated [95% confidence intervals] for risk of composite CVD (first HES outcome of CHD, MI, stable or unstable angina, stroke, TIA, PVD, heart failure, PCI and CABG) in men and women under and over the age of 50 years. Result(s): 2,988 (52.5% women) SB register participants had HES records. The SMbR was higher in women than men in both age groups and during both time periods. Compared to 1997-2007, in both men and women aged <50 years the SMbR fell significantly in the 2008-2017 period (8.7[7.3-10.3] vs 17.9[15.7-20.5] and 12.8[10.4-15.7] vs 20.8[17.1-25.4] respectively. By contrast in both sexes in those >50 years in the later time period there was no significant reduction in CVD-admission incidence rates or in SMbR (Men, 6.6[5.3-8.2] vs 5.8[5.0-6.8], Women, 9.2[7.8-10.7] vs 7.5 [6.6-8.5]). Conclusion(s): While the rate of CVD morbidity due to FH has encouragingly fallen significantly over time in both sexes aged <50 years, it has not done so in those >50. This emphasises the importance of early identification and optimal lipid-lowering throughout life for subjects with FH. Funded by the NIHR HTA project 15/134/02 and BHF grants RG3008 and PG008/08.

Author(s):*Gupta M; *Dosu A; *Makan J

Citation:Cureus, 2022 May 11; Vol. 14 (5), pp. e24899

Abstract:Holt-Oram syndrome is a rare autosomal dominant disorder which occurs because of mutations in the TBX5 genes. Most notable manifestations include musculoskeletal deformities, predominantly affecting the upper limbs, and congenital heart defects. Presentation could be multifaceted leading to delay in diagnosis. We describe an interesting incidental diagnosis of Holt-Oram syndrome in a young female adult who accompanied her son to the clinic. He had undergone closure of both atrial septal defect (ASD) and patent ductus arteriosus (PDA) in his infancy. She reported progressive exertional dyspnoea, reduced exercise tolerance, and palpitations; incidentally, she was noted to have right upper limb deformities. These findings prompted further evaluation and thereafter, resulted in a diagnosis of Holt-Oram syndrome.

Abstract:
Aims The aim of this review to assess cardiac involvement in patients with severe COVID-19 patients. We review all patients with COVID 19 disease admitted in our trust requiring transthoracic echocardiograms on their clinical indications. Background Cardiac involvement in COVID-19 disease has been found to be prognostic factor and has been related with higher mortality and morbidity. In a large series with COVID-19 those with heart disease had a fatality rate around 10.5%.1 2 Methods All adult patients who were COVID-19 positive on PCR admitted between March 2020 and February 2021, who had an echocardiogram, were identified through our local database. Their demographics, co-morbid, troponin levels and Pro NT-BNP were analysed. All echocardiograms reports which were finalised by the imaging cardiologist were included in our analysis. Results There were a total of 41 patients who had echocardiograms during their stay in the hospital with COVID-19 disease. Mean age was 70 (range 45-90) years old. There were 70% male and 30% female patients. 12% were diabetic, 49% hypertensive and 40% had previous heart disease. Pulmonary embolism diagnosed in 10% of patients by CT pulmonary angiogram. 56% of patients required high flow oxygen and 21% need mechanical ventilation. Almost all patients had troponin and CRP levels on admission. Mean troponin level 215 and mean CRP levels were 197. Mean D dimer levels 1130, and mean creatinine levels were 138. 92% had evidence of lung involvement in chest X-ray. 13% patients had new evidence of a diagnosis of left ventricular dysfunction on echocardiography. Similarly, 27% had a new diagnosis of right ventricular dysfunction. Mean left ventricular diastolic dimension were 4.6 cm and systolic dimension. 2% had echo diagnosis of left ventricular thrombus echocardiographic studies. Mean PA pressure on echocardiography were 35 mmHg and mean E/A ratio was 1.2. 17% of patients were found to have pericardial effusion but none causing haemodynamic compromise. Conclusion This data suggests high incidence of right and left ventricular involvement in patients with severe COVID-19 disease. We recommend that all patients with COVID-19 disease admitted to hospital and requiring oxygen should have transthoracic echocardiograms during their admission.

Abstract:
Introduction Multi-modality imaging plays a significant role in evaluating and interval monitoring of patients with aortopathies. Echocardiogram is the first screening test followed by Computerised Tomography (CT) and/ or Magnetic Resonance Imaging (MRI). Most patients require repeated scans at interval. Both CT and MRI require contrast administration and furthermore, radiation exposure in CT. Locally, we have c adopted surveillance scanning with non-contrast MR to overcome the above limitations. This is not widely practised. Aim The aim of the study is to compare inter-modality agreement between CT (gold standard) and non-contrast MRI measurements of ascending aortic dimensions. Methods 126 consecutive patients underwent non-contrast
MRI thoracic aorta our hospitals between 2017 and 2021. Thirty-eight patients (61% males, age 61+/-14 years) have had both CT and MRI. A retrospective analysis was conducted to assess the inter-modality agreement of ascending aorta measurements. Statistical analysis was done using R programme (R studio). A Bland-Altman graph was used to assess inter-modality agreement of ascending aorta measurements. Differences in measurements of the two modalities were reported as mean and 95% confidence interval. Results There is good linear correlation (Pearson's R=0.86, p<0.05) between CT and MRI measurements. Mean difference between CT and MRI measurements was 2.39mm, 95% confidence interval 6.5mm to 8.4mm, see figure 1. Conclusion
There is good inter-modality agreement of ascending aorta measurements between CT non contrast MRI in our experience. Non contrast MRI has the advantage of requiring no radiation and no need for contrast. This is desirable particularly in young patients requiring long term surveillance.

Abstract:
Introduction COMPASS trial has recommended that low-dose rivaroxaban reduces major adverse cardiac and limb events among patients with stable atherosclerotic vascular disease. In the real-world practice, the recommendations from COMPASS trial can be used as a standard to recognise potentially suitable patients. The objective of our study was to establish the cohort of patients identified as COMPASS-eligible for low dose rivaroxaban. Methods A health service evaluation of Cardiology Outpatients from Shrewsbury and Telford Hospital NHS Trust (SaTH) was carried out. The specific characteristics of the selected cohort included known stable atherosclerotic vascular disease while the inclusion and exclusion criteria incorporated in the COMPASS
trial was used as a standard. The SaTH clinical databases from January 2021 were utilized to conduct a retrospective analysis to identify patients who could prospectively benefit from low-dose rivaroxaban. Results Among the 99 patients who were found to have stable atherosclerotic vascular disease, 34 patients were deemed eligible for low dose rivaroxaban. Patients in our COMPASS-eligible group included 26 patients who were >=65years of age while 8 patients were noted to be <65 years of age. Further analysis revealed that 94% of the patients had coronary artery disease as compared with only 6% found to have peripheral artery disease. In this cohort of patients, 79 % of the non-eligible patients were excluded due to underlying atrial fibrillation. Conclusion About one-third of our cohort of patients met the COMPASS criteria and could potentially benefit from low dose rivaroxaban therapy. There is certainly a strong mandate for introduction of rivaroxaban
following the COMPASS trial recommendations. Local protocols should be established to ensure that this window of opportunity to prevent major adverse cardiovascular and limb events is not missed in the clinical practice.

Abstract:
Myocardial bridges are anatomical entities characterized by myocardium covering segments of coronary arteries. In some patients, the presence of a myocardial bridge is benign and is only incidentally found on autopsy. In other patients, however, myocardial bridges can lead to compression of the coronary artery during systolic contraction and delayed diastolic relaxation, resulting in myocardial ischemia. This ischemia in turn can lead to myocardial infarction, ventricular arrhythmias and sudden cardiac death. Myocardial bridges have also been linked to an increased incidence of atherosclerosis, which has been attributed to increased shear stress and the presence of vasoactive factors. Other studies however, demonstrated the protective roles of
myocardial bridges. In this study, using systematic review and a meta-analytical approach we investigate the prevalence and morphology of myocardial bridges in both clinical imaging and cadaveric dissections. We also discuss the pathophysiology, clinical significance, and management of these anatomical entities.

Abstract:
The subspecialty of cardio-oncology aims to reduce cardiovascular morbidity and mortality in patients with cancer or following cancer treatment. Cancer therapy can lead to a variety of cardiovascular complications, including left ventricular systolic dysfunction, pericardial disease, and valvular heart disease. Echocardiography is a key diagnostic imaging tool in the diagnosis and surveillance for many of these complications. The baseline assessment and subsequent surveillance of patients undergoing treatment with anthracyclines and/or human epidermal growth factor (EGF) receptor (HER) 2-positive targeted treatment (e.g. trastuzumab and pertuzumab) form a significant proportion of cardio-oncology patients undergoing echocardiography. This guideline from the British Society of Echocardiography and British Cardio-Oncology Society outlines a protocol for baseline and surveillance echocardiography of patients undergoing treatment with anthracyclines and/or trastuzumab. The methodology for acquisition of images and the advantages and disadvantages of techniques are discussed. Echocardiographic definitions for considering cancer therapeutics-related cardiac dysfunction are also presented.

Abstract:
Introduction: Pre-COVID-19, the total number of passengers traveling by commercial airlines rose to 4.3 billion, with Europe amounting to a 7.2% increase. The risks of respiratory compromised patients developing hypoxaemia during flight is well documented. Assessment of these patients is time consuming and often requires specialised equipment. Furthermore, the majority of evidence is based on research into patients with Chronic Obstructive Pulmonary Disease (COPD). The aim of this study is to investigate potential predictive biomarkers relating to the development of hypoxaemia during flight in patients with Motor Neurone Disease (MND). Method(s): 118 MND patients referred into a fitness to fly service (n=118) completed baseline lung function and a Hypoxic Challenge Test (HCT) as part of a risk stratification for (Table presented) planned air travel (77 male). Data from patients requiring inflight oxygen was compared to patients who did not, in accordance with the British Thoracic Society recommendations 2011: Managing passengers with stable respiratory disease planning air travel. Statistical analysis was performed using one-way ANOVA, Kruskal-Wallis, and Chi-Squared tests, as appropriate. Result(s): There was no significant difference between the pass (n=94) and fail (n=24) groups for age, gender, smoking history or BMI. There was a significant difference for all spirometry data (FEV1, FVC and FEV1/FVC ratio – absolute, percent predicted and standardised residuals). Moreover, the resting blood gases (FiO221%) data showed significant difference for all parameters with the exception of pH (<0.001). The Regression analysis showed limited predictive value of spirometry and/or resting blood gas data with the exception of PaCO2 and base excess (BE). Conclusion(s): The predictive value of spirometic paraments and resting blood gases are limited in assessing hypoxaemia during commercial flight in MND patients, with the exception of parameters relating to respiratory failure. Despite the significant difference between the two groups, routine physiological data was limited in the predictive regression equations. We recommend that the safest approach in managing this group of patients is to perform an HCT in all patients intending to use air travel until more evidence-based data is available.
