Association of potato consumption with calcified atherosclerotic plaques in the coronary arteries: The NHLBI Family Heart Study.

BACKGROUND AND AIMS: While the association of potato consumption with risk factors for coronary artery disease has been inconsistent, no data are available in the literature on the influence of potato consumption on subclinical disease. Thus, we sought to examine whether baked/mashed potato consumption is associated with calcified atherosclerotic plaques in the coronary arteries. METHODS AND RESULTS: In a cross-sectional design, we studied 2208 participants of the NHLBI Family Heart Study. These subjects were selected based on their elevated cardiovascular disease risk compared to the general population. Potato consumption was assessed by a semi-quantitative food frequency questionnaire. We defined prevalent CAC using an Agatston score of at least 100 and fitted generalized estimating equations to calculate prevalence odds ratios of CAC. Mean age at initial clinic visit was 58.2 years and 55% were female. Median consumption of potatoes was 2-4/week. There was no statistically significant association between frequency of potato consumption and prevalent CAC: odds ratios (95% CI) for CAC were 1.0 (reference), 0.85 (0.56-1.30), 0.85 (0.58-1.26), and 0.95 (0.60-1.53) among subjects reporting potato consumption of <1/week, 1/week, 2-4/week, and 5+/week, respectively (p for linear trend 0.83), adjusting for age, sex, BMI, smoking, exercise, diabetes, hypertension, total calories, prevalent coronary heart disease, income, education, and daily red meat intake. CONCLUSIONS: We found no significant association between baked/mashed potato consumption and CAC in older adults. STUDY REGISTRATION NUMBER: NCT00005136. Study registration date: 5/25/2000.

Rare Manifestation of COVID-19 Resulting in Coronary Artery Vasculitis.

We present the case of a 59-year-old African American female with end-stage renal disease (ESRD) who presented to the emergency department with chest discomfort. She had a coronary angiogram six months ago that showed no occlusive epicardial coronary artery disease. She had elevated troponin I levels and new regional wall motion abnormalities on echocardiogram. Her SARS-CoV-2 returned positive. After a multidisciplinary team approach, she underwent another coronary angiogram that showed new severe multivessel ostial lesions and a left main coronary artery aneurysm. COVID-19-related coronary artery vasculitis was suspected based on her clinical presentation, angiogram findings, and negative autoimmune workup. The patient underwent successful coronary artery bypass grafting and recovered without complications.

Long-Term Major Adverse Cardiovascular Events in Patients "Appropriately" Tested for Troponin Assays in Emergency Department.

Cardiac biomarkers like troponin have become essential for detecting myocardial ischemia, a hallmark of the acute coronary syndrome (ACS), in the emergency department (ED). However, inappropriate and excessive biomarker testing can lead to false positive results, patient anxiety, and unnecessary treatment. Our study aimed to develop an appropriateness criterion for troponin testing and examine the long-term major adverse cardiac events (MACE) of patients tested with troponin in the ED. We retrospectively evaluated 407 patients who underwent troponin testing at a tertiary-care northeastern US hospital. The majority (n = 252, 62%) of troponin testing was appropriate, with the remainder deemed inappropriate. Baseline characteristics were equally distributed between the 2 groups. Of the appropriately ordered troponins, 34% were positive compared to 28% of the inappropriately ordered troponins (range 0.04-0.10 ng/mL). Patients were followed over 540 days. MACE occurred in 21% and 10% of patients in the appropriate and inappropriate groups, respectively. Unlike the inappropriate group (3.5%), 96% of the events in the appropriate group occurred within the first 200 days. Patients in the appropriate group were at an increased adjusted risk of MACE (HR 2.55, 95% CI (1.59-4.08), P < 0.001) on long-term follow-up. In addition, MACE was comparable between patients with positive and negative troponins in the inappropriate group (HR 1.46, 95% CI (0.28-7.71), P = 0.65). Our study supports judicious troponin testing and the need for robust appropriateness criteria for ordering troponin in the ED to avoid overdiagnosis and inappropriate testing.

Outcomes of transcatheter aortic valve replacement in patients with mitral annular calcification and concomitant mitral valve dysfunction: A systematic review and meta-analysis.

BACKGROUND: Calcific aortic stenosis is the principal indication for transcatheter aortic valve replacement (TAVR). Comorbid mitral annular calcification (MAC) is often present in patients undergoing TAVR. Limited data exist on the impact of MAC on TAVR outcomes. We conducted a systematic review and meta-analysis to explore the effects of MAC and concomitant mitral valve dysfunction (MVD) on TAVR outcomes. METHODS: A comprehensive literature review was conducted using PubMed, Embase, Google Scholar, ClinicalTrials.gov, Scopus, and OVID for studies until March 20, 2023. Using the random-effects Mantel-Haenszel method, we calculated pooled risk ratios (RRs) and their corresponding 95 % confidence intervals (CIs) for all dichotomous variables. RESULTS: Six studies comprising 5822 patients (2541 with MAC [severe MAC (>4 mm thickness) 583; non-severe MAC 1958; 400 with MVD; and 1071 without MVD], 3281 without MAC) met inclusion criteria. At 30 days and 1 year, no significant differences were observed between the overall MAC and no MAC groups in terms of mortality, stroke, and permanent pacemaker implantation. However, MAC with MVD was associated with a higher risk of all-cause mortality compared to MAC without MVD at 30 days (RR = 3.43, 95 % CI 2.04-5.76, P < 0.00001) and at 1 year (RR = 2.44, 95 % CI 1.85-3.20, P < 0.00001). Moreover, the risk of cardiovascular mortality was higher in patients with MAC and MVD compared to those with MAC alone (RR = 2.77, 95 % CI 1.89-4.06, P < 0.00001). Additionally, patients with severe MAC had a higher risk of major bleeding at 30 days compared to the non-severe MAC group (RR = 1.33, 95 % CI 1.04-1.69, P = 0.02). CONCLUSION: TAVR appears to be safe in patients with non-severe MAC, but severe MAC is associated with a higher risk of major bleeding and concomitant MVD increases the mortality risk in patients undergoing TAVR.

Unraveling a rare presentation of bivalvular infective endocarditis using POCUS.

Infective endocarditis (IE) is rare, and involvement of two valves is rarer yet. We present a case of a 22-year-old male with liver failure who was found to have bivalvular IE. This case sheds light on the association between bivalvular IE and seemingly unrelated symptoms, emphasizing the need for early recognition.

Beyond the norm: A rare case of cardiac and extracardiac metastatic urothelial carcinoma.

Screening echocardiography aids in identifying cardiac emboli causes and asymptomatic cardiac metastases in high-grade neoplasms. Conversely, cardiac MRI provides advanced tissue characterization and broader extracardiac assessment.

Intracranial metastasis from prostate adenocarcinoma: a case report and literature review.

Intracranial metastasis from prostate adenocarcinoma is rare. A 70-year-old African American male with a history of prostate adenocarcinoma for the last 14 years, presented to our hospital complaining of generalized weakness for the past 2 weeks. He was found to have fever with left ptosis and mild eyelid edema. Brain MRI showed dural metastasis. Two months after the first presentation, he was readmitted with a suspected acute cerebral vascular accident (CVA). CT brain showed vasogenic edema in the right subcortical, likely from intracranial metastasis. His acute neurological symptoms improved with intravenous dexamethasone. This case highlights the possibility of intracranial metastasis from prostate adenocarcinoma. With the advent of novel therapies for prostate cancer, which prolong life expectancy, intracranial metastasis from prostate adenocarcinoma may become an increasingly frequent clinical scenario.

Clinical Use of Diuretics in Heart Failure, Cirrhosis, and Nephrotic Syndrome.

Diuretics play significant role in pharmacology and treatment options in medicine. This paper aims to review and evaluate the clinical use of diuretics in conditions that lead to fluid overload in the body such as cardiac failure, cirrhosis, and nephrotic syndrome. To know the principles of treatment it is essential to understand the underlying pathophysiological mechanisms that cause the need of diuresis in the human body. Various classes of diuretics exist, each having a unique mode of action. A systemic approach for management is recommended based on the current guidelines, starting from thiazides and proceeding to loop diuretics. The first condition for discussion in the paper is cardiac failure. Treatment of ascites in liver cirrhosis with spironolactone as the primary agent is highlighted with further therapeutic options. Lastly, management choices for nephrotic syndrome are discussed and recommended beginning from basic sodium restriction to combined diuretic therapies. Major side effects are discussed.
