ABSTRACT

PURPOSE OF REVIEW: This article presents a comprehensive review of coronary revascularization versus optimal medical therapy (OMT) in patients with severe ischemic left ventricular dysfunction. RECENT FINDINGS: The REVIVED-BCIS2 trial randomized 700 patients with extensive coronary artery disease and left ventricular (LV) ejection fraction (LVEF) ≤ 35% and viability in more than four dysfunctional myocardial segments to percutaneous coronary intervention (PCI) plus OMT versus OMT alone. Over a median duration of 41 months, there was no difference in the composite of all-cause mortality, heart failure hospitalization, or improvement in LVEF with PCI plus OMT versus OMT alone at 6 and 12 months, quality of life scores at 24 months, or fatal ventricular arrhythmia. The STICH randomized trial was conducted between 2002 and 2007, involving patients with LV dysfunction and coronary artery disease. The patients were assigned to either CABG plus medical therapy or medical therapy alone. At the 5-year follow-up, the trial showed that CABG plus medical therapy reduced cardiovascular disease-related deaths and hospitalizations but no reduction in all-cause mortality. However, a 10-year follow-up showed a significant decrease in all-cause mortality with CABG. The currently available evidence showed no apparent benefit of PCI in severe ischemic cardiomyopathy as compared to OMT, but that CABG improves outcomes in this patient population. The paucity of data on the advantages of PCI in this patient population underscores the critical need for optimization of medical therapy for better survival and quality of life until further evidence from RCTs is available.

ABSTRACT

RATIONALE & OBJECTIVE: Patients receiving maintenance dialysis have higher mortality after primary percutaneous coronary intervention (pPCI) than patients not receiving dialysis. Whether pPCI confers a benefit to patients receiving dialysis that is similar to that which occurs in lower-risk groups remains unknown. We compared the effect of pPCI on in-hospital outcomes among patients hospitalized for ST-elevation myocardial infarction (STEMI) and receiving maintenance dialysis with the effect among patients hospitalized for STEMI but not receiving dialysis. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: We used the National Inpatient Sample (2016-2018) and included all adult hospitalizations with a primary diagnosis of STEMI. PREDICTORS: Primary exposure was PCI. Confounders included dialysis status, demographics, insurance, household income, comorbidities, and the elective nature of the admission. OUTCOME: In-hospital mortality, stroke, acute kidney injury, new dialysis requirement, vascular complications, gastrointestinal bleeding, blood transfusion, mechanical ventilation, palliative care, and discharge destination. ANALYTICAL APPROACH: The average treatment effect (ATE) of pPCI was estimated using propensity score matching independently within the group receiving dialysis and the group not receiving dialysis to explore whether the effect is modified by dialysis status. Additionally, the average marginal effect (AME) was calculated accounting for the clustering within hospitals. RESULTS: Among hospitalizations, 4,220 (1.07%) out of 413,500 were for patients receiving dialysis. The dialysis cohort was older (65.2 ± 12.2 vs 63.4 ± 13.1, P < 0.001), had a higher proportion of women (42.4% vs 30.6%, P < 0.001) and more comorbidities, and had a lower proportion of White patients (41.1% vs 71.7%, P < 0.001). Patients receiving dialysis were less likely to undergo angiography (73.1% vs 85.4%, P < 0.001) or pPCI (57.5% vs 79.8%, P < 0.001). Primary PCI was associated with lower mortality in patients receiving dialysis (15.7% vs 27.1%, P < 0.001) as well as in those who were not (5.0% vs 17.4%, P < 0.001). The ATE on mortality did not differ significantly (P interaction = 0.9) between patients receiving dialysis (-8.6% [95% CI, -15.6% to -1.6%], P = 0.02) and those who were not (-8.2% [95% CI, -8.8% to -7.5%], P < 0.001). The AME method showed similar results among patients receiving dialysis (-9.4% [95% CI, -14.8% to -4.0%], P < 0.001) and those who were not (-7.9% [95% CI, -8.5% to -7.4%], P < 0.001) (P interaction = 0.6). Both the ATE and AME were comparable for other in-hospital outcomes in both groups. LIMITATIONS: Administrative data, lack of pharmacotherapy and long-term outcome data, and residual confounding. CONCLUSIONS: Compared with conservative management, pPCI for STEMI was associated with comparable reductions in short-term mortality among patients irrespective of their receipt of maintenance dialysis.

ABSTRACT

PURPOSE OF REVIEW: The optimal antithrombotic strategy in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) remains the subject of controversy. In this article, we review the current evidence for the use of triple therapy in acute coronary syndrome (ACS) patients. RECENT FINDINGS: The recently published trials of AF patients undergoing PCI have shown that combination of non-vitamin K oral anticoagulants (NOACs) with an antiplatelet agent is either superior or non-inferior to vitamin K antagonist (VKA) plus dual antiplatelet therapy (DAPT) in reducing bleeding complications with no difference in regard to thromboembolic events. Currently, the use of dual therapy (preferably with a NOAC and clopidogrel) is recommended over triple therapy in these patients. The optimal duration should be guided by the assessment of an individual's risk of thrombosis and bleeding events.

ABSTRACT

INTRODUCTION: The optimal approach to deal with severe coronary artery calcification (CAC) during percutaneous coronary intervention (PCI) remains ill-defined. METHODS: We conducted an electronic database search of all published studies comparing Orbital versus Rotational Atherectomy in patients undergoing PCI. RESULTS: Eight observational studies were included in the analysis. Overall, there were no significant differences in Major-adverse-cardiac-events/MACE (OR: 0.81, CI: 0.63-1.05, p = .11), myocardial-infarction/MI (OR: 0.75, CI: 0.56-1.00, p = .05), all-cause mortality (OR: 0.82, CI: 0.25-2.64, p = .73) or Target-vessel-revascularization/TVR (OR: 0.72, CI: 0.38-1.36, p = .31). However, OA was associated with lower long-term MACE (1-year), (OR: 0.66, CI: 0.44-0.99, p = .04), long-term TVR (OR: 0.40, CI: 0.18-0.89, p = .03), and short-term MI (in-hospital and 30-day) (OR: 0.64, CI: 0.44-0.94, p = .02). OA was associated with more coronary artery dissections (OR: 2.61, CI: 1.38-4.92, p = .003) and device-related coronary perforations (OR: 2.79, CI: 1.08-7.19, p = .03). There were no differences in cardiac tamponade (OR: 1.78, CI: 0.37-8.69, p = .47). OA was noted to have significantly lower fluoroscopy time (MD: -3.96 min, CI: -7.67, -0.25; p = .04) compared to RA. No significant difference was noted in terms of contrast volume between the two groups (OR: -4.35 ml, CI: -14.52, 23.22; p = .65). CONCLUSION: Although there was no difference in overall MACE, MI, all-cause mortality and TVR, OA was associated with lower long-term MACE and short-term MI. OA is associated with lower fluoroscopy time but higher rates of coronary artery dissection and coronary perforation.

ABSTRACT

AIMS: There are limited data on the management and outcomes of chronic liver disease (CLD) patients presenting with acute myocardial infarction (AMI), particularly according to the subtype of CLD. METHODS: Using the Nationwide Inpatient Sample (2004-2015), we examined outcomes of AMI patients stratified by severity and sub-types of CLD. Multivariable logistic regression was performed to assess the adjusted odds ratios (aOR) of receipt of invasive management and adverse outcomes in CLD groups compared with no-CLD. RESULTS: Of 7 024 723 AMI admissions, 54 283 (0.8%) had a CLD diagnosis. CLD patients were less likely to undergo coronary angiography (CA) and percutaneous coronary intervention (PCI) (aOR 0.62, 95%CI 0.60-0.63 and 0.59, 95%CI 0.58-0.60, respectively), and had increased odds of adverse outcomes including major adverse cardiovascular and cerebrovascular events (1.19, 95%CI 1.15-1.23), mortality (1.30, 95%CI 1.25-1.34) and major bleeding (1.74, 95%CI 1.67-1.81). In comparison to the non-severe CLD sub-groups, patients with all forms of severe CLD had the lower utilization of CA and PCI (P < .05). Among severe CLD patients, those with alcohol-related liver disease (ALD) had the lowest utilization of CA and PCI; patients with ALD and other CLD (OCLD) had more adverse outcomes than the viral hepatitis sub-group (P < .05). CONCLUSIONS: CLD patients presenting with AMI are less likely to receive invasive management and are associated with worse clinical outcomes. Further differences are observed depending on the type as well as severity of CLD, with the worst management and clinical outcomes observed in those with severe ALD and OCLD.

ABSTRACT

BACKGROUND: Diastolic function (DF) guidelines have been simplified but lack extensive outcome data. Using a rural university heart failure (HF) database, we assessed whether DF grading could predict HF, HF readmission, and all-cause mortality (ACM). METHODS: In this single-center retrospective study that included 613 patients in sinus rhythm hospitalized for HF (HF with preserved-254 patients, with mid-range-216 patients, and reduced ejection fraction-143 patients), we recorded demographics, Doppler-echo, Framingham HF score, laboratories, HF readmission, and ACM with follow-up to 2167 days. RESULTS: Diastolic dysfunction (Ddys) parameters (left atrial volume index [LAVI] > 34 ml/m2 , tricuspid regurgitation [TR] velocity > 2.8 m/sec, and E/e' > 14) had moderate sensitivity (46.2%-65.0%) for predicting HF among all phenotypes combined with DF grading having moderate predictability and additive to a clinical composite for HF prediction (AUC = .677, P < 0.0001; difference = .043, P < 0.001) for combined phenotypes. Ddys parameters and Ddys severity (2016 ASE criteria: grade II and III) were significantly associated with HF readmission for decompensated HF within 60-2167 days of follow-up (LAVI > 34 ml/m2 : HR 1.56 [1.26-2.19]; E/e' > 14: HR 1.44 [1.21-1.99]; TR > 2.8 m/sec: H1.43 [1.19-1.88]; LV Dys grade II: HR 2.12 [1.42-2.96]; LV Ddys grade III: HR 2.39 [1.57-4.82]). CONCLUSION: The findings of this study highlight the clinical and prognostic relevance of determining the severity of LV Ddys in patients with HF with regard to HF verification and HF readmission.

ABSTRACT

PURPOSE OF REVIEW: Electronic cigarettes (e-cigarettes) are gaining rapid popularity among all age groups, especially among youth. They have evolved into technologically advanced devices capable of delivering nicotine concentration and other substances. In addition to nicotine, e-cigarettes' constituents possess variety of toxic chemicals that have adverse effects on human body. RECENT FINDINGS: In recent years, steady downward trend in tobacco usage has been observed; however, e-cigarette use is on upward trend. E-cigarettes are advertised as "safer" alternatives to conventional smoking and as an aid to smoking cessation. Emerging studies have, however, shown that e-cigarettes have harmful effects on the cardiovascular system and that most of the e-cigarette users are dual users, concurrently using e-cigarettes and smoking conventional cigarettes. Despite a gap in clinical studies and randomized trials analyzing adverse cardiovascular effects of e-cigarette use, the existing literature supports that different constituents of e-cigarettes such as nicotine, carbonyls, and particulate matters carry potential risk for cardiovascular diseases (CVD) on its users.

ABSTRACT

PURPOSE OF REVIEW: This article reviews the evidence on optimal medical therapy (OMT) versus coronary revascularization in patients with stable ischemic heart disease (SIHD) and advanced chronic kidney disease (CKD). RECENT FINDINGS: A post hoc analysis of the COURAGE trial in patients with SIHD and CKD showed no difference in freedom from angina, death, and nonfatal myocardial infarction (MI) between OMT and percutaneous intervention plus OMT compared with patients without CKD. The ISCHEMIA-CKD trial of 777 patients with advanced CKD revealed no difference in cumulative incidence of death or nonfatal MI at 3 years between OMT and revascularization but the composite of death or new dialysis was higher in the invasive arm. Additionally, there were no significant or sustained benefits in related to angina-related health status in invasive versus conservative strategy. An initial revascularization strategy does not reduce mortality or MI or relieve angina symptoms in patients with SIHD and advanced CKD.

ABSTRACT

Introduction: This study aimed to examine the association of smoking status with homocysteine levels and to determine whether the association is modified by oestradiol or cholesterol.Methods: Data (N = 4580) were obtained from National Health and Nutrition Examination Survey 2003-2004 with analysis done in 2018 on adults aged ≥20 years. The outcome was homocysteine; smoking status was the exposure variable and categorized as current, former or never smoker. Generalized linear models were used to examine the associations between smoking status and homocysteine levels, while assessing the impact of oestradiol and cholesterol.Results: After adjusting for age, sex, ethnicity, education and income level, homocysteine levels did differ by smoking status ((current smokers versus never smokers: ß: 0.18 CI: 0.00, 0.36), (former smokers: ß: 0.10 CI: -0.09, 0.28)). The addition of oestradiol as an interaction term in adjusted models was associated with a 16.6% increase in homocysteine levels when compared to models without the interaction term. Oestradiol but not cholesterol did moderate the association between smoking status and homocysteine levels.Discussion and conclusions: Homocysteine levels did differ across smoking status after adjusting for confounders. Oestradiol did moderate the relationship between homocysteine and smoking status.

ABSTRACT

PURPOSE OF REVIEW: To review the clinical evidence on the use of percutaneous coronary intervention (PCI) revascularization options in left main (LM) disease in comparison with coronary artery bypass graft (CABG). Coronary artery disease (CAD) involving the LM is associated with high morbidity and mortality. Though CABG remains the gold standard for complex CAD involving the LM artery, recent trials have shown a trend towards non-inferiority of the LM PCI when compared with CABG in certain subset of patients. RECENT FINDINGS: Two recent major randomized trials compared the outcomes of PCI versus CABG in the LM and multi-vessel disease with LM involvement. The NOBLE trial included patients with all range of Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) scores and utilized biolimus drug-eluting stent (DES). The trial concluded that MACCE (major adverse cardiac and cerebrovascular event) was significantly higher with PCI (28%) when compared with CABG (18%) but overall stroke and motility were not different. EXCEL trial evaluated the same treatment option in low to intermediate SYNTAX score population with third-generation everolimus DES platform as PCI option. Results showed no significant differences in the composite primary endpoints of death, stroke, and myocardial infarction (MI) at the end of 30 days (22% versus 19.2%, p = 0.13), although repeat revascularization was higher in PCI group (16.9% versus 10%). Recent evidence suggests that PCI is an acceptable alternative to treat symptomatic LM stenosis in select group of patients. In low to medium SYNTAX score, particularly in patients without diabetes mellitus, PCI remains a viable option. Future trials focusing on evaluating subset of patients who would benefit from one particular revascularization option in comparison with other is warranted.

ABSTRACT

PURPOSE OF REVIEW: Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) have emerged as the invasive diagnostic tools of choice for hemodynamic assessment of the severity of CAD (coronary artery disease). We sought to comprehensively review the evidence on the utility of hemodynamic assessment of the coronary stenoses after percutaneous coronary intervention (PCI) using FFR/iFR, mechanisms of positive post-PCI iFR/FFR, and the clinical impact of significant residual ischemia. RECENT FINDINGS: The evidence on the utility of the post-PCI hemodynamic assessment has accumulated over the last few years. The post hoc analysis from the FAME 1 and FAME 2 data shows that higher post-PCI FFR is associated with better symptomatic improvement and lower event rate with larger increase in delta FFR (∆ FFR: post-PCI FFR - pre-PCI FFR). Unlike pre-PCI FFR, a consensus has not been established on the optimal value of post-PCI FFR, though multiple studies point toward better clinical outcomes with higher post-PCI FFR and larger ∆ FFR. Visual assessment of adequate stent apposition by coronary angiography is insufficient in evaluating for residual ischemia. The hemodynamic evaluation of residual ischemia by post-PCI FFR/iFR yields clinically relevant data and allows for appropriate post PCI optimization.

ABSTRACT

OBJECTIVE: The central Appalachian region of the United States is disproportionately burdened with cardiovascular disease (CVD); however, the level of literacy about CVD among residents has not been well studied. This study aimed to examine the prevalence and factors of CVD health literacy (HL) among a sample of patients/caregivers, providers/professionals, and community stakeholders. METHODS: In 2018, data were collected from central Appalachian residents in six states: Kentucky, North Carolina, Ohio, Tennessee, Virginia, and West Virginia. CVD HL status was determined by assessing correct responses to five interrelated questions about basic knowledge of CVD. Multiple logistic regression analyses were used to examine the associations between potential factors and CVD HL status. RESULTS: Of the total respondents (N = 82), <50% correctly answered all 5 CVD HL questions. Multiple logistic regression analyses showed that compared with respondents with advanced college degrees, those with a college degree or less were more likely to have low HL for "typical symptom of CVD," "physical exercise and CVD," "blood pressure and CVD," and "stress and CVD." In addition, compared with respondents younger than 50 years, those 50 years and older were 3.79 times more likely to have low HL for "physical exercise and CVD." CONCLUSIONS: These results suggest the incorporation of CVD HL into CVD care and that educational attainments should be part of CVD policies and programs in the region.

ABSTRACT

Pulmonary hypertension is a life-threatening illness with debilitating physical and emotional consequences. The progression of this devastating disease is characterized by a continuous increase in pulmonary vascular resistance, which results in elevated pulmonary artery pressure and leads to right heart failure. Treatment is focused on targeting the underlying complex etiology via the endothelin, prostacyclin, and nitric oxide (NO) pathways. Emergence of new treatments over the past 2 decades has led to improvement in the functional status and time to clinical worsening. Even with recent advances, outcomes remain suboptimal. Phosphodiesterase-5 (PDE-5) inhibitors, such as sildenafil, were approved for treatment of pulmonary arterial hypertension (PAH) by the Food and Drug Administration (FDA) in 2005, which holds promise in improving quality of life and therefore making this class of medications effective palliative therapy agents. In this review, we summarize the emergence of sildenafil as a treatment for PAH and its role as palliative therapy.

ABSTRACT

PURPOSE OF REVIEW: This article reviews the latest data on unprotected left main (ULM) percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) surgery, with a focus on the NOBLE and EXCEL trials. RECENT FINDINGS: In EXCEL trial, the primary endpoint at 3 years was 15.4% in the PCI group and 14.7% in the CABG group (p = 0.02 for non-inferiority of PCI versus CABG). In NOBLE, the primary endpoint at 5 years was 28% and 18% for PCI and CABG, respectively (HR 1.51, CI 1.13-2.0, which did not meet the criteria for non-inferiority of PCI to CABG; p for superiority of CABG was 0.0044). Higher repeat revascularization and non-procedural myocardial infarction were noted in PCI group but there was no difference in all-cause or cardiac mortality between the two groups. A heart team approach with appropriate patient selection, careful assessment of LM lesions, and meticulous procedural technique makes PCI a valid alternative to CABG for ULM stenosis.

ABSTRACT

BACKGROUND: FDA approved the Gore Viabahn (WL Gore, Flagstaff, AZ, USA) stent for both femoro-popliteal arterial denovo and instent restenosis (ISRS) lesions. To date there is little data on Viabahn stent graft outcomes in ISRS arterial disease. METHODS: Between 2007 and 2014 we identified 734 patients who underwent 1573 endovascular interventions in our institution for infra-inguinal revascularization. Among these, 48 patients had 143 Viabahn stents placed. Of these, 26 patients had 94 stents placed for ISRS and 22 patients had 49 stents placed for denovo lesions. RESULTS: The patients in the ISRS group were younger and more likely to have hypertension, hyperlipidemia, coronary artery disease, compared to the patients in the denovo group. Stents were placed principally for femoro-popliteal lesions, with mean length of 21 ± 12.5 cm (19.2 ± 14, ISRS vs. 22.1 ± 11, denovo; P = 0.2). Both groups had low primary patency rates during one year follow up (54% vs. 33%, OR = 2.3 (0.9-2.2). Target lesion revascularization (TLR) (57% vs. 27%, P < 0.0001, OR = 3.7, CI = 1.8-8) and surgical revascularization (21% vs. 4%, OR = 6.3, CI = 1.4-28) occurred more frequently in the ISRS group than in the denovo group. Amputation rate (17% vs. 31%, OR 0.7, CI = 0.2-1), cumulative blockage (defined as ISRS and thrombosis) (62% vs. 47%, P = 0.09, OR = 1.8, CI = 0.9-3.6), and Restenosis (40% vs. 31%, OR 1.5, CI = 0.7-3.2) were not statistically different between the two groups. Mean duration of follow-up was 12.8 ± 13 months. CONCLUSION: Stent graft treatment using the Gore Viabahn for denovo and ISRS in femoro-popliteal arterial obstructive disease have high restenosis and failure rates, of both stent patency and limb outcomes, which is consistent with existed literature.

ABSTRACT

PURPOSE OF REVIEW: To review the landmark studies in predicting obstructive coronary artery disease (CAD) in symptomatic patients with stable chest pain and identify better prediction tools and propose a simplified algorithm to guide the health care providers in identifying low risk patients to defer further testing. RECENT FINDINGS: There are a few risk prediction models described for stable chest pain patients including Diamond-Forrester (DF), Duke Clinical Score (DCS), CAD Consortium Basic, Clinical, and Extended models. The CAD Consortium models demonstrated that DF and DCS models overestimate the probability of CAD. All CAD Consortium models performed well in the contemporary population. PROMISE trial secondary data results showed that a clinical tool using readily available ten very low-risk pre-test variables could discriminate low-risk patients to defer further testing safely. In the contemporary population, CAD Consortium Basic or Clinical model could be used with more confidence. Our proposed simple algorithm would guide the physicians in selecting low risk patients who can be managed conservatively with deferred testing strategy. Future research is needed to validate our proposed algorithm to identify the low-risk patients with stable chest pain for whom further testing may not be warranted.

ABSTRACT

OBJECTIVES: The central Appalachian region of the United States is disproportionately burdened with cardiovascular diseases (CVD) and associated risk factors; however, research to inform clinical practice and policies and programs is sparse. This study aimed to examine the association between multiple modifiable risk factors for CVD and hypertension in asymptomatic patients in central Appalachia. METHODS: Between January 2011 and December 2012, 1629 asymptomatic individuals from central Appalachia participated in screening for subclinical atherosclerosis. Participants were asked to report their hypertension status (yes/no). In addition, data on two nonmodifiable risk factors (sex, age) and five modifiable risk factors (obesity, diabetes mellitus, hypercholesterolemia, smoking, and sedentary lifestyle) were collected. Multivariable logistic regression analyses were conducted to assess association between hypertension and risk factors. RESULTS: Of the 1629 participants, approximately half (49.8%) had hypertension. Among people with hypertension, 31.4% were obese and 62.3% had hypercholesterolemia. After adjusting for sex and age, obesity and diabetes mellitus were associated with a more than twofold increased odds of having hypertension (odds ratio [OR] 2.02, confidence interval [CI] 1.57-2.60 and OR 2.30, CI 1.66-3.18, respectively). Hypercholesterolemia and sedentary lifestyle were associated with higher odds for hypertension (OR 1.26, CI 1.02-1.56 and OR 1.38, CI 1.12-1.70, respectively), compared with referent groups. Having two, three, and four to five modifiable risk factors was associated with increased odds of having hypertension by about twofold (OR 1.72, CI 1.21-2.44), 2.5-fold (OR 2.55, CI 1.74-3.74), and sixfold (OR 5.96, CI 3.42-10.41), respectively. CONCLUSIONS: This study suggests that the odds of having hypertension increases with a higher number of modifiable risk factors for CVD. As such, implementing an integrated CVD program for treating and controlling modifiable risk factors for hypertension would likely decrease the future risk of CVD.

ABSTRACT

INTRODUCTION: The risk factors for cardiovascular disease (CVD) are associated with coronary atherosclerosis and having multiple risk factors potentiates atherosclerosis. This study examined the prevalence of multiple biological and lifestyle/behavioral risk factors and their association with coronary artery calcium (CAC), a marker for subclinical coronary atherosclerosis. METHODS: This is a cross-sectional study of 1607 community-dwelling asymptomatic individuals from central Appalachia who participated in CAC screening between January 2011 and December 2012. Data on demographics (sex and age) and 7 traditional risk factors for coronary artery disease (CAD) were collected and categorized into 5 groups (0-1, 2, 3, 4, and ≥5). Prevalence of these risk factors and CAC scores (0, 1-99, 100-399, ≥400) were assessed, and the impact of the number of risk factors on CAC scores were delineated using multiple logistic regression. RESULTS: Over 98% of participants had ≥1 risk factor. While obesity, diabetes, hypertension, and family history of CAD significantly increased the odds of having CAC, CAC scores significantly increased with number of risk factors. After adjusting for demographic factors, having 3, 4, and ≥5 risk factors was significantly associated with increased odds of having higher CAC scores when compared to zero CAC score by more than one and half times [OR=1.65, CI (1.20-2.25)], two times [OR=2.32, CI (1.67-3.23)] and three times [OR=3.45, CI (2.42-4.92)], respectively. CONCLUSION: The high prevalence of multiple risk factors in the study population suggests the need for aggressive multiple risk factors interventions for primary prevention of CAD, which could address CVD health disparities.

ABSTRACT

Unicuspid aortic valve (UAV), which is a rare congenital anomaly, usually presents as aortic stenosis and/or aortic regurgitation. Here we present a case of UAV co-existent with an ascending aortic aneurysm. A 26-year-old male with no significant past medical history presented to the hospital after two episodes of syncope. Transthoracic echocardiogram showed an ejection fraction of 62%, severely stenotic aortic valve, and moderate aortic regurgitation. Computed tomography revealed calcification of the aortic valve, compatible with aortic stenosis and aneurysm of the ascending aorta measuring 4.3 cm in diameter. He underwent successful aortic valve replacement and repair of ascending aortic aneurysm. He recovered well without any complications. This case suggests that any young patient who presents with syncope, aortic stenosis would be a differential and further workup by any available non-invasive modality needs to be performed.

ABSTRACT

Systemic lupus erythematosus (SLE) is an autoimmune disease affecting multiple organ systems. Although myocardial involvement and overt myocarditis is rare, life-threatening myocarditis associated with SLE can happen. We report a case of myocarditis associated with SLE with subsequent improvement of cardiac function after immunosuppressive therapy.
