Egg consumption and risk of acute stroke in the Million Veteran Program.

BACKGROUND: While observational data suggest a higher risk of coronary artery disease with frequent egg consumption, only limited and inconsistent data are available on the relation of egg consumption with stroke. OBJECTIVE: The primary objective was to assess whether egg consumption is associated with a higher risk of ischemic and hemorrhagic stroke among US veterans. METHODS: In a prospective cohort study of US veterans from the Million Veteran Program (MVP), egg intake was collected through a self-reported food frequency questionnaire at baseline. Incidence of stroke was ascertained via ICD9/ICD10 codes from the electronic health records. Multivariable Cox proportional hazard models were used to estimate the multivariable adjusted hazard ratios. RESULTS: A total of 233,792 veterans (91.6% men) were studied with a mean age of 65.6 ± 11.7 years. During a mean follow-up of 3.3 years, a total of 5740 cases of fatal and non-fatal ischemic stroke and 423 cases of fatal and non-fatal hemorrhagic stroke occurred. Median egg consumption was 2-4 eggs/week. Crude incidence rates for acute ischemic stroke were 6.5, 7.2, 7.1, 7.4, 8.0, 8.1, and 8.6 cases per 1000 person-years for egg consumption of <1/month, 1-3/month, 1/week, 2-4/week, 5-6/week, 1/day, and ≥2/day, respectively. Corresponding multivariable adjusted hazard ratios (95% CI) were 1.00 (ref), 1.10 (0.96-1.25), 1.09 (0.96-1.23), 1.10 (0.98-1.25), 1.16 (1.01-1.33), 1.20 (1.03-1.40), and 1.22 (1.03-1.45) controlling for age, sex, ethnicity, body mass index, diabetes, smoking, alcohol intake, modified DASH score, and education (p linear trend 0.0085). For hemorrhagic stroke, multivariable adjusted hazard ratios (95% CI) after controlling for age, sex, ethnicity, body mass index, modified DASH score, and level of education were 1.00 (ref), 1.28 (0.96-1.72), 1.22 (0.93-1.61), and 1.19 (0.88-1.61) for egg consumption of <1/week, 1/week, 2-4/week, 5+/week, respectively. CONCLUSION: Our data are consistent with a positive association of egg consumption with acute ischemic stroke but not hemorrhagic stroke among veterans.

Cardiac Biventricular Metastasis From Renal Cell Carcinoma.

Secondary cardiac tumors are much more common than primary tumors. Cardiac metastases from renal cell carcinoma (RCC) are rare and can present many years after the patient has been disease-free. We report the case of a 64-year-old man who had been treated for recurrent metastatic RCC. He presented with shortness of breath, and TEE (transthoracic echocardiography) revealed new biventricular hypertrophy and small-to-moderate circumferential pericardial effusion. Cardiac magnetic resonance demonstrated multiple lesions in both the ventricular walls, highly suspicious for metastasis. A tissue biopsy was obtained, which was inconclusive due to the small sample size. The patient's disease progressively worsened, and, subsequently, he died from cardiac and respiratory failure secondary to the underlying advanced metastatic disease. Cardiac metastasis from RCC is rare and has a wide range of presentations. Metastatic RCC tends to be resistant to chemotherapy and radiotherapy. Systemic therapy (immunotherapy, molecularly targeted agents) and surgery may have a role in these patients depending on the extent of disease and sites of involvement.

Use of Guideline-Directed Medical Therapy in Patients With ST-Elevation Myocardial Infarction.

Introduction ST-elevation myocardial infarction (STEMI) is a serious manifestation of coronary artery disease and remains a significant contributor to morbidity and mortality worldwide. To reduce the risk of recurrent cardiovascular disease (CVD) events, the American College of Cardiology (ACC) and American Heart Association (AHA) recommend the use of five classes of medications after acute coronary syndrome (ACS). The purpose of this study was to evaluate whether STEMI patients admitted to our community hospital were discharged on optimal medical therapy based on the latest AHA/ACC guidelines. Methods A retrospective, single-center electronic medical records review was conducted at our community hospital between July 2017 and December 2018. Patients included in the study were admitted to our hospital through the emergency department as STEMI alerts. We reviewed the discharge prescriptions and assessed compliance with the medication regimen endorsed by AHA/ACC, which includes aspirin, P2Y12 inhibitors, ß-blockers, angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), and statins. Results A total of 147 patients were included in our study. The mean age of our study population was 62 ± 12.48 years. 97.2% of all patients with STEMI underwent coronary angiography. Hypertension (65.9%) was the most common comorbidity followed by hyperlipidemia (54.42%), diabetes mellitus (29.25%), and history of coronary artery disease (CAD) (24.48%). Among patients with successful reperfusion, 87.4% of the patients received the combination of four guideline-directed medical therapy (GDMT) (comprising dual antiplatelet therapy, a ß-blocker, and a statin) and 57% were discharged on five guideline-directed medical treatment (the combination of dual antiplatelet therapy, a ß-blocker, an ACEIs or an ARB, and a statin). Conclusion Optimal secondary prevention medications are known to be effective in reducing the risk of repeat ischemic events in ACS. This study demonstrated that adherence to GDMT in our community-based hospital study is better compared to prior studies but remained suboptimal. Potential strategies to improve adherence to guidelines are necessary.

Focal Neurological Deficit Secondary to Severe Hyponatraemia Mimicking Stroke.

Hyponatraemia is a common electrolyte abnormality seen by internists. Clinical features of hyponatraemia are primarily related to CNS dysfunction, and depend on the severity and acuity of changes in serum sodium concentration. Neurological manifestations of hyponatraemia range from nausea and malaise, with a mild reduction in the serum sodium, to lethargy, decreased level of consciousness, headache, seizures and coma in extreme cases. Focal neurological deficits are very rare in the setting of hyponatraemia. Here, we describe a patient with acute severe symptomatic hyponatraemia presenting with focal neurological deficits that resolved after correction of acute hyponatraemia. LEARNING POINTS: A rare presentation of hyponatraemia is described.Neuroimaging should be performed in patients with focal neurological deficits and hyponatraemia in order to rule out other serious neurological diseases.Correction of severe hyponatraemia can result in resolution of focal neurological deficits.

A case report of atrial myxoma presenting with systemic embolization and myocardial infarction.

BACKGROUND: Cardiac myxomas are the most common benign primary tumour of the heart. Clinical presentation is variable and ranges from constitutional symptoms to clinical features due to intracardiac obstruction, such as mitral stenosis, coronary embolization, or systemic embolization. Surgical resection is the only effective treatment to prevent its debilitating and catastrophic complication. CASE SUMMARY: A 61-year-old woman presented with an-hour history of bilateral leg pain, numbness, lightheadedness, dyspnoea, and diaphoresis. Physical exam was remarkable for pale and cold lower extremities. Arterial pulse was not palpable in the right femoral, popliteal, and posterior tibial and dorsalis pedis arteries bilaterally. Electrocardiogram demonstrated normal sinus rhythm with T-wave inversion in lead I, V2, V3, and V4. Laboratory investigations were remarkable for leucocytosis and elevated troponin. Computed tomography angiogram showed emboli with acute infarcts involving the spleen and kidneys, acute embolic occlusion of right external and internal iliac arteries, and left distal common femoral artery. She underwent emergent bilateral cut-down and femoral artery thrombectomies. Transthoracic echocardiogram demonstrated wall motion abnormalities. Computed tomography angiography of the chest revealed an atrial mass and transoesophageal echocardiography was obtained which confirmed an atrial myxoma. Coronary angiography demonstrated no significant coronary artery disease, raising the possibility of myxoma embolization to the coronary arteries as the cause of her troponin elevation and wall motion abnormality. Subsequently she underwent successful resection of the atrial myxoma. DISCUSSION: The majority of cardiac myxomas are sporadic and arise from the left atrium as an isolated lesion in middle-aged women. Echocardiography is the diagnostic procedure of choice. The long-term survival after surgical resection is excellent and recurrence is rare.

Waist-to-Height Ratio Compared to Standard Obesity Measures as Predictor of Cardiometabolic Risk Factors in Asian Indians in North India.

OBJECTIVE: The aim of this study was to compare the discriminatory ability of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) in identifying the presence of cardiometabolic risk factors in Asian Indians. METHODS: This cross-sectional study involved 509 subjects (278 males and 231 females) aged 20-60 years from New Delhi, India. Measurements included complete clinical examination, blood pressure, weight, height, WC, BMI, WHR and WHtR, fasting blood glucose, lipid profile, and fasting insulin levels. Receiver operating characteristic curve analyses were performed to compare predictive validity of various adiposity measures against the cardiometabolic risk factors (dyslipidemia, hyperinsulinemia, impaired fasting glucose, hypertension, and metabolic syndrome). The odds ratio for the presence of individual cardiometabolic risk factors in the presence of overweight, abdominal obesity, and high WHtR were calculated using logistic regression analysis. RESULTS: WC had the highest area under ROC for all other cardiometabolic risk factors except hyperinsulinemia in males and for dyslipidemia, metabolic syndrome and presence of at least one cardiometabolic risk factor in females. For metabolic syndrome, WC, followed by WHtR, was observed to be the better predictor than other measures of adiposity, and WHtR appeared to be the best predictor for hypertension in both genders, particularly in women. CONCLUSIONS: In the northern Asian Indian population with high prevalence of cardiometabolic risk factors, a combination of WC and WHtR appeared to be having better clinical utility than BMI and WHR in identifying individuals with cardiometabolic risk factors.
