Trends and Disparities in Valvular Heart Disease Mortality in the United States From 1999 to 2020. J Am Heart Assoc 2024; 13:e030895. [PMID: 38587138 DOI: 10.1161/jaha.123.030895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Accepted: 10/19/2023] [Indexed: 04/09/2024]
Abstract
BACKGROUND Percutaneous heart valve procedures have been increasingly performed over the past decade, yet real-world mortality data on valvular heart disease (VHD) in the United States remain limited. METHODS AND RESULTS We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database among patients ≥15 years old from 1999 to 2020. VHD and its subtypes were listed as the underlying cause of death. We calculated age-adjusted mortality rate (AAMR) per 100 000 individuals and determined overall trends by estimating the average annual percent change using the Joinpoint regression program. Subgroup analyses were performed based on demographic and geographic factors. In the 22-year study, there were 446 096 VHD deaths, accounting for 0.80% of all-cause mortality (56 014 102 people) and 2.38% of the total cardiovascular mortality (18 759 451 people). Aortic stenosis recorded the highest mortality of VHD-related death in both male (109 529, 61.74%) and female (166 930, 62.13%) populations. The AAMR of VHD has declined from 8.4 (95% CI, 8.2-8.5) to 6.6 (95% CI, 6.5-6.7) per 100 000 population. Similar decreasing AAMR trends were also seen for the VHD subtypes. Men recorded higher AAMR for aortic stenosis and aortic regurgitation, whereas women had higher AAMR for mitral stenosis and mitral regurgitation. Mitral regurgitation had the highest change in average annual percent change in AAMR. CONCLUSIONS The mortality rate of VHD among the US population has declined over the past 2 decades. This highlights the likely efficacy of increasing surveillance and advancement in the management of VHD, resulting in improved outcomes.

Abstract
Spontaneous coronary artery dissection (SCAD) is the ripping of the epicardial coronary artery wall without any trauma, coronary procedures, or rupture of atherosclerotic plaque. Intimal rip, intramural hematoma, and false lumen formation are the hallmarks of this disease, which may result in coronary blood flow obstruction and myocardial ischemia. The role of SCAD in acute coronary syndrome (ACS), and sudden death has come to light more and more, particularly in young females and those with few typical atherosclerotic risk factors. This study details a 65-year-old female with a history of hypertension, hyperlipidemia, asthma, and chronic kidney disease who presented with severe chest pain and elevated troponin levels. Upon investigation, spontaneous dissection of the left anterior descending artery (LAD) involving its mid and distal segments was identified. The present case highlights a rare occurrence of spontaneous coronary artery dissection (SCAD) in a demographic typically unaffected by the condition - females aged 65 years and over. The atypical presentation underscores the importance of reporting such cases to prevent oversight. This patient's case is particularly noteworthy as it deviates from the typical predisposing factors associated with SCAD, such as youth, pregnancy, or stressors. Additionally, the case is unique in that it presented both SCAD and imaging findings consistent with takotsubo cardiomyopathy, suggesting a complex cardiac pathology deserving of further study and consideration.

Abstract
A 72-year-old woman with recently diagnosed non-small cell lung cancer, who underwent cardiac bypass and bioprosthetic mitral valve replacement presented to our cancer center with lightheadedness, severe fatigue, and shortness of breath. Initial blood tests showed mild hemolytic anemia. The patient also complained of occasional bright red bleeding per rectum. Esophagogastroduodenoscopy and colonoscopy did not reveal an acute source of bleeding. An initial transesophageal echocardiogram did not show significant valvular or paravalvular abnormalities. Meanwhile, the patient's hemolytic anemia worsened. She received eight units of packed red blood cell transfusions. Schematic workup for hemolytic anemia revealed negative Coomb's test, positive urine hemosiderin, normal ADAMTS13 activity, and absent splenomegaly. A relook of the patient's transesophageal echocardiogram (TEE) showed a small paravalvular leak of the bioprosthetic mitral valve. The patient was referred to a tertiary center, and repair of the perivalvular leak with glue resolved her hemolytic anemia, subsequently improving the lab values, symptoms, and quality of life. This case highlights the schematic workup of hemolytic anemia and also the importance of recognizing the association between hemolytic anemia and valvular abnormalities.

Abstract
The implantation of cardiac pacing devices, such as pacemakers and implanted cardioverter-defibrillators (ICDs), has significantly improved patient outcomes in the treatment of a range of cardiac arrhythmias. Right ventricular (RV) pacing lead perforation is an uncommon but potentially dangerous complication that can occur despite technical breakthroughs. RV lead perforation, which can result in right ventricular perforation as well as possible pulmonary or vascular harm, is caused by the pacing lead breaking through the myocardial wall. Despite being rare, this complication warrants attention because of the risks for morbidity and mortality that are involved. We present a case of right ventricular perforation caused by a pacemaker lead and examine the nuances of RV lead perforation in this instance, including its prevalence, clinical presentation, diagnostic difficulties, and treatment strategies, illuminating the many factors to be taken into account while properly managing this issue.

Abstract
Takotsubo cardiomyopathy (TTC) is a severe, acute, reversible, and self-limited cardiac dysfunction. It usually affects postmenopausal women and is mostly triggered by physical or emotional stressors. Following the COVID-19 pandemic, millions of doses of different types of COVID-19 vaccines are being administered globally. There have been reports of different cardiac complications after receiving COVID-19 vaccines. To our knowledge, there have been 16 reported cases of COVID-19 vaccination-associated TTC. In this study, we first provide a brief overview of TTC and then an overview of selected reported TTC cases following COVID-19 vaccinations. It is crucial to highlight that the occurrence of TTC after vaccination does not establish a direct cause-and-effect relationship between immunization and TTC. Further investigations are necessary to examine any potential association between COVID-19 vaccines and the incidence of TTC. Additionally, the benefits of receiving COVID-19 vaccines significantly outweigh the potential risks of developing adverse events.

Abstract
Coronavirus disease 2019 (COVID-19)-induced pericarditis and pericardial myocarditis are common entities; however, the development of pericardial effusion post-COVID-19 infection has only been reported in about 5% of cases. Rapid and acute progression to pericardial tamponade is uncommon, and progression to effusive constrictive pericarditis (ECP) and pericardial decompression syndrome (PDS) is an even rarer phenomenon. We describe these phenomena in this report to raise awareness and aid clinicians in the early diagnosis and management of these conditions. We report a case of a 45-year-old female with a past medical history of recent COVID-19 infection, uncontrolled diabetes mellitus, and hypertension who presented with severe chest pain, which was determined to be acute pericarditis post-COVID-19 infection. The patient developed a large pericardial effusion leading to cardiac tamponade within one day of initial presentation. Urgent pericardiocentesis was performed but was complicated by rapid decompensation of the patient, which has been assumed to be ECP following pericardiocentesis and PDS. Close monitoring of acute pericarditis with pericardial effusion is required in these patients for the early detection of cardiac tamponade, which requires urgent pericardiocentesis. Judicious post-pericardiocentesis follow-up is also required for the early diagnosis of conditions such as ECP and PDS. These cases are generally managed symptomatically, but in cases of severe ECP syndrome, pericardial stripping may be required.

Abstract
Sarcoidosis is a disease that involves multiple organs, including the cardiovascular system. While cardiac sarcoidosis has been increasingly recognized, the impact of sarcoidosis on atrial fibrillation (AF) is not well established. This study aimed to analyze the impact of sarcoidosis on in-hospital outcomes among patients who were admitted for a primary diagnosis of AF. Using the all-payer, nationally representative Nationwide Readmissions Database, our study included patients aged ≥18 years who were admitted for AF between 2017-2020. We stratified the cohort into two groups depending on the presence of sarcoidosis diagnosis. The in-hospital outcomes were assessed between the two groups via propensity score analysis. A total of 1031 (0.27%) AF patients with sarcoidosis and 387,380 (99.73%) AF patients without sarcoidosis were identified in our analysis. Our propensity score analysis of 1031 (50%) patients with AF and sarcoidosis and 1031 (50%) patients with AF but without sarcoidosis revealed comparable outcomes in early mortality (1.55% vs. 1.55%, P = 1.000), prolonged hospital stay (9.51% vs. 9.70%, P = .874), non-home discharge (7.95% vs. 9.89%, P = .108), and 30-day readmission (13.29% vs. 13.69%, P = .797) between the two groups. The cumulative cost of hospitalization was also similar in both groups ($12,632.25 vs. $12,532.63, P = .839). The in-hospital adverse event rates were comparable in both groups. Sarcoidosis is not a risk factor for poorer in-hospital outcomes following AF admission. These findings provide valuable insights into the effectiveness of the current guideline for AF management in patients with concomitant sarcoidosis and AF.

Abstract
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS), often associated with atherosclerosis. However, SCAD has been increasingly recognized as a distinct entity, especially in young females without traditional cardiovascular risk factors. We present a case of a 56-year-old female with systemic lupus erythematosus (SLE) who developed multivessel SCAD involving the right coronary artery (RCA) and ramus. The patient's clinical presentation included typical chest pain, elevated troponins, and ST depressions on electrocardiography. Coronary angiography confirmed the presence of SCAD, classified as type 4 in the RCA and type 2 in the ramus. Prompt diagnosis and treatment resulted in a favorable prognosis. This case emphasizes the importance of considering SCAD in SLE patients presenting with ACS symptoms, particularly in younger women without evident cardiovascular risk factors. Early invasive coronary angiography is recommended for accurate diagnosis and timely management. SCAD can lead to significant complications and requires meticulous attention during angiographic procedures. Conservative management is often preferred, as most uncomplicated cases of SCAD heal spontaneously. Further research is needed to determine optimal treatment strategies and long-term outcomes for patients with SCAD, especially in the presence of underlying inflammatory conditions like SLE.

Abstract
Coronavirus disease 2019 and influenza B can have similar presentations and are self-limited in most cases. They are rarely associated with fatal cardiovascular complications. Coronavirus and influenza B-induced myocarditis is a rare but reversible cause of cardiogenic shock. Early detection plus administration of antiviral agents and supportive care with mechanical circulatory support in the form of an intra-aortic balloon pump can be a lifesaving measure in myocarditis.

Abstract
Reversing neuromuscular blockade with sugammadex can eliminate residual paralysis, which has been associated with postoperative respiratory complications. There are equivocal data on whether sugammadex reduces these when compared with neostigmine. We investigated the association of the choice of reversal drug with postoperative respiratory complications and advanced healthcare utilisation. We included adult patients who underwent surgery and received general anaesthesia with sugammadex or neostigmine reversal at two academic healthcare networks between January 2016 and June 2021. The primary outcome was postoperative respiratory complications, defined as post-extubation oxygen saturation < 90%, respiratory failure requiring non-invasive ventilation, or tracheal re-intubation within 7 days. Our main secondary outcome was advanced healthcare utilisation, a composite outcome including: 7-day unplanned intensive care unit admission; 30-day hospital readmission; or non-home discharge. In total, 5746 (6.9%) of 83,250 included patients experienced postoperative respiratory complications. This was not associated with the reversal drug (adjusted OR (95%CI) 1.01 (0.94-1.08); p = 0.76). After excluding patients admitted from skilled nursing facilities, 8372 (10.5%) patients required advanced healthcare utilisation, which was not associated with the choice of reversal (adjusted OR (95%CI) 0.95 (0.89-1.01); p = 0.11). Equivalence testing supported an equivalent effect size of sugammadex and neostigmine on both outcomes, and neostigmine was non-inferior to sugammadex with regard to postoperative respiratory complications or advanced healthcare utilisation. Finally, there was no association between the reversal drug and major adverse cardiovascular events (adjusted OR 1.07 (0.94-1.21); p = 0.32). Compared with neostigmine, reversal of neuromuscular blockade with sugammadex was not associated with a reduction in postoperative respiratory complications or post-procedural advanced healthcare utilisation.

Abstract
Surgical aortic valve replacement (SAVR) is the current treatment of choice for good surgical candidates with moderate to severe symptomatic aortic stenosis (AS). As transcatheter aortic valvular replacement (TAVR) has shown an improved one and two-year all-cause mortality, it has been chosen for moderately symptomatic severe AS patients. The purpose of this review was to perform a clinical comparison of TAVR vs. SAVR and to analyze the Health Index Factor (HIF) that makes TAVR a treatment of choice in asymptomatic AS patients. An extensive literature search of PubMed, Cochrane, and Embase databases was performed using the keywords “Aortic stenosis”, “SAVR”, “TAVR”, and “Asymptomatic”. A total of 45 prospective randomized clinical trials in the English language that were published from the year 2000 onwards were included in the final analysis. It has been found that 59.3% of asymptomatic AS patients are likely to die in the next five years without proactive treatment. Multiple studies have proven that early intervention with aortic valve replacement is superior to conservative treatment in severe asymptomatic AS; however, the choice between SAVR and TAVR is not well established. The NOTION Trial, SURTAVI Trail, and PARTNER 3 study have shown the non-inferiority of TAVR over SAVR, during one-year follow-up for low surgical risk patients. Evolut Low-Risk study and Early TAVR are the only two prospective studies performed to date that have enrolled patients with asymptomatic severe AS. The Evolut Trial demonstrated no difference in all-cause mortality at 30 days (1.3% vs. 4.8%. p=0.23), and 12 days (1.3% vs. 6.5%, p=0.11). Additionally, TAVR also decreases the risk of post-procedural atrial fibrillation, acute kidney injury (AKI), and rehospitalization, and leads to significant improvement in the mean trans-aortic pressure gradient. TAVR also showed marked improvement in the 30-day Quality of Life (QOL) index, where SAVR did not report any significant change in the QOL index. However, the official recommendations of Early TAVR are still awaited. TAVR has consistently shown a statistically non-significant difference in case mortality, risk of stroke, and rehospitalization with moderate to high surgical risk patients whereby recent initial trials have shown significant improvement in the QOL index and hemodynamic index for patients with asymptomatic disease. More extensive studies are required to prove the risk stratifications, long-term outcomes, and clinical characteristics that would make TAVR a preferred intervention in asymptomatic patients.

Abstract
BACKGROUND This study aimed to translate and validate an Arabic version of the Functional Assessment of Cancer Therapy Head and Neck Scale (FACT-H&N, v-4) for use among Sudanese oral cancer patients. METHODS The instrument underwent translation and validation following the standard FACT translation methodology. The translated instrument was pre-tested for face validity and content validity using semi-structured, in-depth interviews with ten oral cancer patients to assess acceptability. The questionnaire was pilot tested with 60 patients; reliability was tested for internal consistency with Cronbach's alpha while construct validity was tested using 'known-group validity'. RESULTS The pre-test study revealed no major issues, apart from a reluctance to answer questions on sexual satisfaction. The FACT-H&N demonstrated good internal consistency, it considered five particular constructs: PWB, SWB, EWB, FWB and FACT-H&N, their Cronbach's α values were positive and close to 1 with values of 0.85, 0.788, 0.86, 0.895 and 0.703 respectively, indicating that the questionnaire was valid and the responses consistent. Sixty patients were asked the global health-related quality of life item, 36.3% rated their QOL as very good or good (36.3%), while 41.7% rated it as average, and 21.7% as poor or very poor. Then FACT subscale mean scores were tabulated against three categories; patients with very poor/poor recorded significantly lower scores indicating construct validity. Some psychometric properties were consistent with other FACT-H&N translations such as the Chinese, French, Pakistani and Malaysian. CONCLUSIONS This study validates the Arabic version of the FACT-H&N. It is a reliable tool and, will assist further QoL research in other Arabic-speaking countries.

Abstract
Spontaneous coronary artery dissection (SCAD) is an uncommon disease which can lead to acute coronary syndrome especially in young females. The risk factors associated with SCAD include connective tissue disorder, atherosclerosis, hormonal disturbances, history of physical and emotional stressors. Based on angiographic assessment SCAD is divided into three types. We present a unique case of multiparous female with concomitant type 1 and type 2 angiographic features of SCAD. The patient was started on medical therapy with close follow-up. This case highlights the importance of physician awareness about the occurrence of this rare cardiac condition in a young female without any significant risk factors.

Abstract
Aortic dissection (AD) is an injury to the innermost layer of the aorta, leading to the formation of a false lumen. AD usually presents with tearing chest pain radiating to the back and is a medical emergency. Other common symptoms include abdominal pain, diaphoresis, loss of consciousness, shortness of breath, stroke-like symptoms, or leg pain. Here, we present a rare case of an incidental finding of asymptomatic AD on computed tomography angiography performed after cardiac catheterization failure. The patient had a history of aortic aneurysm, hypertension, and heart failure. Appropriate imaging should be performed to rule out the possibility of AD in patients with risk factors and cardiac catheterization failure.

Abstract
Ascending aortic is an uncommon site for arterial thrombosis and ascending aortic thrombosis is a very rare phenomenon with a high fatality rate. Marijuana is the most commonly used psychoactive drug in the United States and a few cases have been reported on the association of marijuana with vascular thromboembolism. However, the pathophysiology and exact mechanism are still not well studied. Herein, we present a case of a 44-year-old female with active marijuana use presented with ascending aortic thrombus associated with acute arterial occlusion of the right vertebral artery and bilateral renal artery. The unique part of this case is that the patient did not have the classical risk factors for vascular thromboembolic disease. The only risk factor was marijuana smoking. To our best knowledge, this is one of the unique cases of marijuana-associated with ascending aorta thrombosis.

Abstract
Spontaneous coronary artery dissection (SCAD) is a grave medical condition that is defined as a separation of the coronary artery wall layer. This presentation is rare in males and can be triggered by cardio-circulatory stress, such as exercise and emotional stress. Sexual intercourse is considered potent cardiovascular stress that can be strenuous and cause rapid and significant changes in the heart rate and blood pressure which can predispose SCAD. Herein, we are reporting a very rare case of a 41-year-old male gentleman who presented with SCAD after vigorous sexual intercourse. We are reporting this case to encourage physicians to educate their patients on the topic.

Abstract
Esophagogastroduodenoscopy (EGD) is one of the forefronts of minimally invasive modalities with excellent safety records and tremendous capability but despite its accolades and functions, there are still very rare complications including air embolism. It is a life-threatening condition that could lead to a significant increase in morbidity and mortality. However, there are limited data for incidence of air embolism in association with gastrointestinal endoscopy. Diagnosis of air embolism after or during gastrointestinal endoscopy might be a difficult task due to overlapping presentations with anesthesia effects on the cardiopulmonary and the neurological systems, as a result, there should be increased awareness allowing clinicians to quickly rule out air embolism in patient with altered mental status or cardiopulmonary changes after or during gastrointestinal endoscopy. Herein, we report a unique case of cerebral air embolism after EGD in a 79-year-old female patient. In addition, we also performed a systematic review of cases based on PRISMA guideline, with the aim to investigate the demographics and clinical outcomes associated with this complication. This systematic review of cases hopes to increase the awareness about this rare entity.

Abstract
Left ventricular thrombus typically occurs in patients with impaired left ventricular function such as aneurysm, dilated cardiomyopathy, or post-myocardial infarction. Untreated HIV infection is known to increase the risk of venous thromboembolism and cardiovascular disease. However, the pathophysiology remains uncertain; some studies have proposed chronic inflammation as the underlying etiology. Nonetheless, left ventricular thrombus is extremely rare among persons living with HIV with no known underlying cardiac disease. Herein, we report an unusual case of a 55-year-old homeless and heterosexual male with past medical history of HIV, who has mildly reduced left ventricular function and a nonmobile, medium size left ventricular thrombus. Patient was initially treated with therapeutic dose of enoxaparin, and subsequently developed acute embolic occlusion of right femoral artery that lead to an above knee amputation. To our knowledge, left ventricular thromboembolism complicated with acute embolic ischemia in persons living with HIV is extremely rare. The presenting case will definitely add to the current body of knowledge and will raise awareness among physicians, in recognizing the rare association between HIV and arterial thromboembolism.

Abstract
Hypothermia defined as a core body temperature less than 35°C causes hundreds of deaths annually in the United States. It can occur in a variety of clinical settings, including environmental exposure, shock, infection, metabolic disorders, alcohol, or drug toxicity, and malnutrition. This condition can affect many different organ systems and may lead to serious complications including cardiac arrhythmia. Hypothermia is extremely rare in people living with HIV but can be seen in severely malnourished patients or those who are not receiving antiretroviral therapy (ART). It is a life-threatening situation that should be treated aggressively. To the best of our knowledge, there are only a few cases that have been reported for people living with HIV presenting with hypothermia and sinus bradycardia. Herein, we are reporting a very rare case of people living with AIDS who presented with hypothermia complicated by sinus bradycardia. In addition, we also performed a systematic review of cases based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, to investigate the clinical characteristics and outcomes associated with this rare complication. This systematic review of cases hopefully can increase the awareness of this rare entity and help improve its outcome.

Abstract
Coronavirus disease 2019 (COVID-19) has overwhelmed healthcare globally with millions of cases and over 2 million deaths worldwide. The hypercoagulable state associated with COVID-19 is a well-recognized complication that carries a poor prognosis. Marantic endocarditis, or non-bacterial thrombotic endocarditis (NBTE), is caused by a sterile vegetation on the cardiac valves resulting from the deposition of fibrin and platelet aggregates. It is highly associated with the hypercoagulable and acquired inflammatory states. Herein, we report a unique and rare case of COVID-19 presenting with NBTE. LEARNING POINTS COVID-19 has caused a major global pandemic, with high morbidity and mortality.One of the complications of COVID-19 infection is a hypercoagulable state.To the best of our knowledge, we present only the second case of marantic endocarditis in a patient with COVID-19, in the hope of raising awareness among physicians of this potential rare association.

Abstract
Carotid artery dissection begins as a tear in one of the carotid arteries of the neck, which allows blood under arterial pressure to enter the wall of the artery and split its layers. The result is either an intramural hematoma or an aneurysmal dilatation. It is a significant cause of neurological signs and symptoms in all age groups. The common carotid artery dissection is the least affected and reported in the literature. There are multiple conditions that can cause the common carotid artery dissection including, trauma, procedures, and rarely spontaneous. Herein, we report a very unique and rare case of a female who presented with spontaneous and isolated common carotid artery dissection with no neurological signs and symptoms.

Abstract
Background Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection can lead to many different cardiovascular complications, we were interested in studying prognostic markers in patients with atrial fibrillation/flutter (A. Fib/Flutter). Methods A retrospective cohort study of patients with confirmed COVID-19 and either with existing or new onset A. Fib/Flutter who were admitted to our hospital between March 15 and May 20, 2020. Demographic, outcome and laboratory data were extracted from the electronic medical record and compared between survivors and non-survivors. Univariate and multivariate logistic regression were employed to identify the prognostic markers associated with mortality in patients with A. Fib/Flutter Results The total number of confirmed COVID-19 patients during the study period was 350; 37 of them had existing or new onset A. Fib/Flutter. Twenty one (57%) expired, and 16 (43%) were discharged alive. The median age was 72 years old, ranged from 19 to 100 years old. Comorbidities were present in 33 (89%) patients, with hypertension (82%) being the most common, followed by diabetes (46%) and coronary artery disease (30%). New onset of atrial fibrillation was identified in 23 patients (70%), of whom 13 (57%) expired; 29 patients (78%) presented with atrial fibrillation with rapid ventricular response, and 2 patients (5%) with atrial flutter. Mechanical ventilation was required for 8 patients, of whom 6 expired. In univariate analysis, we found a significant difference in baseline ferritin (p=0.04), LDH (p=0.02), neutrophil-lymphocyte ratio (NLR) (p=0.05), neutrophil-monocyte ratio (NMR) (p=0.03) and platelet (p=0.015) between survivors and non-survivors. With multivariable logistic regression analysis, the only value that had an odds of survival was a low NLR (odds ratio 0.74; 95% confidence interval 0.53–0.93). Conclusion This retrospective cohort study of hospitalized patients with COVID-19 demonstrated an association of increase NLR as risk factors for death in COVID-19 patients with A. Fib/Flutter. A high NLR has been associated with increased incidence, severity and risk for stroke in atrial fibrillation patients but to our knowledge, we are first to demonstrate the utilization in mortality predictions in COVID-19 patients with A. Fib/Flutter. Disclosures Jihad Slim, MD, Abbvie (Speaker’s Bureau)Gilead (Speaker’s Bureau)Jansen (Speaker’s Bureau)Merck (Speaker’s Bureau)ViiV (Speaker’s Bureau)

Abstract
The global pandemic of severe acute respiratory syndrome coronavirus 2 has caused significant morbidity and mortality, not only causing devastating lung injury but also has an enormous effect on the cardiovascular system. The hypercoagulable state associated with coronavirus 2019 plays a major role in the disease manifestation. Venous thromboembolism including pulmonary embolism remains the most common thrombotic manifestation of the disease as compared to arterial thrombosis. Nonetheless, the co-occurrence of both venous and arterial thrombosis in a coronavirus 2019 patient, to our knowledge, has rarely been reported. Herein, we are presenting a case of co-occurrence of left ventricular thrombosis with pulmonary embolism in the setting of coronavirus 2019 with successful treatment with apixaban.

Abstract
Aortic dissection is a life-threatening condition that may present as severe acute chest or abdominal pain, especially in high-risk patients, and should raise a high index of suspicion for aortic dissection when occurring after moderate-to-high-intensity activities, such as sexual intercourse. Sexual intercourse leads to physiological stress on the body causing an abrupt elevation in blood pressure and shearing force against the vessel wall. This shearing force increases the risk of vessel wall dissection. Below, we discuss a rare case of type A aortic dissection after sexual intercourse and highly recommend physicians to evaluate and educate their high-risk patients regarding aortic dissection with such activities.

Abstract
Setting: Needle and Syringe Exchange Programme (NSEP) implemented by non-governmental organisations in Malaysia. Objectives: To determine enrolment, characteristics and retention in the NSEP of people who inject drugs (PWID) between 2013 and 2015. Design: Retrospective cohort study. Results: There were 20 946 PWID, with a mean age of 38 years. The majority were male (98%) and of Malay ethnicity (92%). Follow-up data were available for 20 761 PWID. Annual retention of newly enrolled PWID for each year was respectively 85%, 87% and 78% for 2013, 2014 and 2015, although annual enrolment over these years declined from 10 724 to 6288 to 3749. Total person-years (py) of follow-up were 27 806, with loss to follow-up of 40 per 100 py. Cumulative probability of retention in NSEP was 66% at 12 months, 45% at 24 months and 26% at 36 months. Significantly higher loss to follow-up rates were observed in those aged 15-24 years or ⩾50 years, females, transgender people and non-Malay ethnic groups. Conclusion: Annual retention of new PWID on NSEP was impressive, although enrolment declined over the 3 years of the study and cumulative loss to follow-up was high. A better understanding of these programmatic outcomes is required.

Abstract
Electrovestibulography (EVestG™) is a new technology that objectively measures the vestibular response. It has the potential to objectively, quickly and cost-effectively screen concussion. EVestG signals are recorded painlessly and non-invasively from the external ear in response to vestibular stimuli, and consist of brainstem and peripheral sensory oto-acoustic signals modulated by the cortical responses. In this study, we investigated the relationship between characteristic features of the extracted field potentials (FPs) of EVestG signals in people with side-impact concussion in comparison with those of control participants. 10 side-impact concussed individuals (4 Right and 6 left side-impact) and 10 age-and-gender-matched controls were tested by EVestG. The participants also completed comprehensive neuropsychological assessments. Characteristic features were extracted from the FPs during side tilt, and linear discriminant analysis (LDA) classification was applied to the extracted features using a leave-one-out routine. The results show the difference between the left and right FP area was significantly (P<0.05) different. The LDA classification resulted a sensitivity of 85% and specificity of 69% for separating concussed individuals from controls. EVestG appears to have diagnostic potential in diagnosing side impact concussion.

Abstract
This study was designed to investigate the alteration of redox status by commonly used antimalarials in Nigeria. Drugs used were artemisinin, artesunate, chloroquine, coartem and quinine at the final concentrations of 0.5–8.0 mg/mL. Blood samples were collected from malarial patients and apparently healthy humans for comparison. Reduced glutathione, catalase, superoxide dismutase (SOD) activities, protein content and lipid peroxidation were determined. All drugs significantly ( p < 0.05) increases the protein level relative to control in normal blood, whereas in the infected, a significant ( p < 0.05) reduction was observed. In normal blood, the antimalarials dose dependently decreased ( p < 0.05) SOD and catalase activities with significant ( p < 0.05) increase in the infected. The level of glutathione in normal blood significantly ( p < 0.05) increases as compared with control, whereas in the infected, similar observation was made except that the levels were less, relative to control sample. Malondialdehyde level significantly ( p < 0.05) increases with increase in drugs concentration even though less than the level in the control with few exceptions. These effects were dose dependent and more pronounced in non-malarial conditions. Commonly used antimalarials might alter the redox status in both healthy and non-healthy subjects thereby inducing oxidative stress.

Abstract
Allergic reactions to pacemaker device components are uncommon. However, when they occur, they usually mimic pacemaker infection, which results in multiple device replacements and increased morbidity burden. Here we present a 40-year-old female with pacemaker insertion due to complete heart block and who had multiple device replacements because of allergic sensitivity to various pacemaker component-encasing materials, confirmed by allergic testing to these materials. She had complete resolution of her symptoms after replacement with gold-plated device, to which she was not allergic.

Abstract
OBJECTIVES The electrocardiographic abnormalities associated with ischaemic stroke and subarachnoid haemorrhage have been described frequently and studied systematically; however, these changes were not investigated thoroughly in patients with intracranial parenchymal haemorrhage (IPH). METHODS We retrospectively reviewed the electrocardiograms (ECGs) and medical records of all patients who had been diagnosed with acute intraparynchemal haemorrhage (IPH) between 2006 and 2009. RESULTS We included 160 patients (56% males). The median age was 71 years (interquartile range (IQR) 59 to 80) and 69% were above the age of 60 years. Most patients were hypertensive (81%).The majority of patients (86%) had at least one ECG abnormality. Sixty-eight (43%) patients had T-wave inversion and 65 (41%) had QTc interval prolongation. There was a significant association between QTc prolongation and the bleeding size and the presence of midline shift; odd ratios were 2.8 (CI 1.4 to 5.5; P 0.003) and 2.2 (CI 1.1 to 4.2; P 0.04), respectively. In addition, sinus tachycardia was found to be significantly associated with the presence of hydrocephalus (OR 4.1; CI 1.3 to 12.8; P 0.02). CONCLUSIONS ECG abnormalities are a common finding in patients with IPH. Repolarizaion abnormalities occur the most frequently. QTc prolongation was associated with bleeding size and midline shift. Patients who had hydrocephalus were more likely to have sinus tachycardia at presentation.
