Impact of educational intervention on hypertension management by primary care physician: A randomized control trial.

Objective: The current study aimed to observe hypertension educational intervention's effect on general physicians (GPs) to improve blood pressure control and patient outcomes indirectly. Methods: This randomized control trial includes 42 GPs divided into 2 groups. GPs in group 1 receive face-to-face education with structured educational material on hypertension management strategies by a senior cardiologist. GPs in group 2 receive the print version of education material. The data was collected from six major cities in Pakistan. GPs with at least three years of experience in the broad primary care disciplines, with ages above 18 years, were included in the study. Results: A total of 42 physicians (21 from each group) completed questionnaires, while out of 420 hypertension patients, 105 newly diagnosed and already diagnosed patients enrolled under physicians of both groups. The educational material did just as well at informing clinicians as the face-to-face group intervention did and both the interventions had a significant effect on knowledge and BP control. Conclusion: After the 3-month follow-up, both interventions, including face-to-face and educational approaches, demonstrated significant effectiveness in improving knowledge and blood pressure control. Innovation: The study shows that hypertension educational intervention's effect on general physicians indirectly improves blood pressure control and patient outcomes. And emphasize for developing a hypertension educational program targeted at general physicians.

Cardiovascular Health and Disease in the Pakistani American Population.

PURPOSE OF REVIEW: This narrative review seeks to elucidate clinical and social factors influencing cardiovascular health, explore the challenges and potential solutions for enhancing cardiovascular health, and identify areas where further research is needed to better understand cardiovascular issues in native and American Pakistani populations. RECENT FINDINGS: The prevalence of cardiometabolic disease is high not only in Pakistan but also among its global diaspora. This situation is further complicated by the inadequacy of current cardiovascular risk assessment tools, which often fall short of accurately gauging the risk among Pakistani individuals, underscoring the urgent need for more tailored and effective assessment methodologies. Moreover, social determinants play a crucial role in shaping cardiovascular health. The burden of cardiovascular disease and upstream risk factors is high among American Pakistani individuals. Future research is needed to better understand the heightened risk of cardiovascular disease among Pakistani individuals.

PAKistan Study of prEmature coronary atHerosclerosis in young AdulTs (PAK-SEHAT): a prospective longitudinal study protocol investigating the prevalence, severity and determinants of atherosclerotic cardiovascular disease in the young adult Pakistani population.

INTRODUCTION: Atherosclerotic cardiovascular disease (ASCVD) is a major cause of morbidity, mortality and health expenditures worldwide. Despite having higher ASCVD in the Pakistani population, data on subclinical coronary atherosclerosis in young Pakistanis remain scarce. The PAKistan Study of prEmature coronary atHerosclerosis in young AdulTs (PAK-SEHAT) aims to assess the prevalence, severity and determinants of subclinical coronary atherosclerosis among Pakistani men (35-60 years) and women (35-65 years) free of clinically symptomatic ASCVD and will assess 5-year rates of ASCVD events. METHODS AND ANALYSIS: PAK-SEHAT is an ongoing prospective cohort study with 2000 participants from all provinces of Pakistan who will be interviewed at the baseline along with phlebotomy, measurement of carotid intima-media thickness (CIMT) and coronary CT angiography (CCTA). Phlebotomy will be repeated at 2.5 years, whereas CIMT and CCTA will be repeated at 5 years. We will report the frequency of maximal coronary stenosis ≥50% and ≥70%, number of coronary vessels with plaque and the number of coronary segments affected per participant on CCTA. We will use Cox proportional hazards regression models to evaluate the association between baseline characteristics and incident ASCVD events during follow-up. These associations will be presented as HRs with 95% CIs. ETHICS AND DISSEMINATION: The study protocol was approved by the Tabba Heart Institute Institutional Review Board (THI/IRB/FQ/22-09-2021/016). All study procedures are consistent with the principles of the Declaration of Helsinki. Findings of the study will be disseminated via peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT05156736.

Global Cardiovascular Research: Gaps and Opportunities.

PURPOSE OF REVIEW: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. CVDs contribute to a large health and economic burden on a global scale. We aim to describe the current landscape of global cardiovascular research, highlight significant findings, and identify potential opportunities for further studies. RECENT FINDINGS: There has been remarkable research output regarding cardiovascular health in recent decades. Large-scale collaborative studies have made impactful strides in identifying modifiable risk factors and forming evidence-based guidelines to facilitate improved cardiovascular care and outcomes. However, there are significant CVD disparities between high- and low- income countries which require interventions to mitigate these inequalities. Encouraging collaborative partnerships, strengthening research capacity in low-resource settings, and promoting equity in research are fundamental strategic approaches to help improve global cardiovascular research.

Clinical characteristics, management, and 5-year survival compared between no standard modifiable risk factor (SMuRFless) and ≥ 1 SMuRF ACS cases: an analysis of 15,051 cases from Pakistan.

BACKGROUND: There has been an increase in Acute Coronary Syndrome (ACS) patients without standard modifiable risk factors i.e. hypertension, diabetes, dyslipidemia, and tobacco use (SMuRFless) compared to the patients with ≥ 1 SMuRF but this has not been studied in South Asia despite them being a high-risk population. We conducted a comparative analysis of first episodes of ACS cases admitted to a tertiary cardiac center in Pakistan between SMuRFless and ≥ 1 SMuRF patients for clinical presentation, management, in-hospital, and 5-year mortality. METHODS: We undertook a retrospective study and data of 15,051 patients admitted at Tabba Heart Institute (THI) with the first episode of ACS was extracted from Chest Pain-MI™, and the CathPCI Registry® registry affiliated with the National Cardiovascular Data Registry (NCDR®), USA. Logistic regression and Cox proportional algorithm yielded odds ratio (OR) and hazard ratios (HR) with 95% confidence interval (CI) for associated factors of in-patient and 5-year mortality. RESULTS: There were 15% SMuRFless cases and in-hospital mortality was 4.1% in SMuRFless vs. 3.9% in the ≥ 1 SMuRF group (p-0.59), the difference remained insignificant after adjusting for age, gender, Killip class, multivessel disease, type of ACS, percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) (Adjusted OR:1.1 [0.8, 1.3]. Unadjusted 5-year mortality was 40% lower in the SMuRFless group but the difference was insignificant after adjusting for age, gender, disease at presentation, its severity, and management (Adjusted HR 0.7 95% CI[0.5, 1.0]). STEMI, NSTEMI, Killip class, and multivessel disease increased the risk of overall 5-year mortality. CONCLUSION: In-hospital and 5-year mortality was not different between the SMuRFless and ≥ 1 SMuRF group, there is a need to understand mediators of immediate and long-term mortality risk in SMuRFless patients.

Gender Differences in Clinical Outcomes After Percutaneous Coronary Intervention-Analysis of 15,106 Patients from the Cardiac Registry of Pakistan Database.

There is a scarcity of data on gender differences in outcomes during and after percutaneous coronary intervention (PCI) in the South Asian population. We assessed the gender differences in in-hospital mortality and complications in patients who underwent PCI. We conducted a cross-sectional study of 15,106 patients from the CROP (Cardiac Registry of Pakistan) CathPCI database. Logistic regression was used to determine factors associated with in-hospital mortality (primary outcome), access site hematoma, and bleeding complications. Approximately 19.6% were women. Women were older (mean age = 57.3 vs 54.4 years) and had a higher prevalence of diabetes (49.3% vs 32.6%), hypertension (72.8% vs 56.4%), peripheral arterial disease (1.5% vs 1%), and cerebrovascular accident (1.2% vs 0.8%) than men (p <0.05).Unadjusted in-hospital mortality was higher in women than in men (odds ratio [OR]: 1.6, 95% confidence interval [CI] 1.1 to 2.2); however, after adjusting for age, hypertension, diabetes, history of cerebrovascular accident, and ST-elevation myocardial infarction at presentation in the multiple logistic regression model, in-hospital mortality was comparable between men and women (adjusted OR [AOR] 1.2, 95% CI 0.8 to 1.7). The results remained consistent after propensity score matching of 5,904 patients (2,952 in each group, OR 1.3, 95% CI 0.9 to 2.0 for in-hospital mortality). Bleeding complications (1.2% vs 0.4%, AOR 2.6, 95% CI 1.4 to 4.5) and access site hematoma (2% vs 0.6%, AOR 2.8, 95% CI 1.8 to 4.5) were higher in women than in men. In conclusion, the incidence of in-hospital mortality was higher for women versus men, but adjusted risks were similar, likely driven by a greater co-morbidity burden among women.

Healthcare Access Among Individuals of Asian Descent in the U.S.

Introduction: Some groups of Asian Americans, especially Asian Indians, experience higher rates of atherosclerotic cardiovascular disease (ASCVD) compared with other groups in the U.S. Barriers in accessing medical care partly may explain this higher risk as a result of delayed screening for cardiovascular risk factors and timely initiation of preventive treatment. Methods: Cross-sectional data were utilized from the 2006 to 2015 National Health Interview Survey (NHIS). Barriers to accessing medical care included no place to seek medical care when needed, no healthcare coverage, no care due to cost, delayed care due to cost, inability to afford medication, or not seeing a doctor in the past 12 months. Results: The study sample consisted of 18,150 Asian individuals, of whom 20.5% were Asian Indian, 20.5% were Chinese, 23.4% were Filipino, and 35.6% were classified as "Other Asians". The mean (standard error) age was 43.8 (0.21) years and 53% were women. Among participants with history of hypertension, diabetes mellitus, or ASCVD (prevalence = 25%), Asian Indians were more likely to report delayed care due to cost (2.58 (1.14,5.85)), while Other Asians were more likely to report no care due to cost (2.43 (1.09,5.44)) or delayed care due to cost (2.35 (1.14,4.86)), compared with Chinese. Results among Filipinos were not statistically significant. Conclusions: Among Asians living in the U.S. with cardiovascular risk factors or ASCVD, Asian Indians and Other Asians are more likely to report delayed care or no care due to cost compared with Chinese.

Frequency, Risk Factors, and Outcome of Definite Stent Thrombosis: A Single-Center Experience.

Introduction Stent thrombosis (ST) is a serious and potentially life-threatening complication of primary or complex high-risk percutaneous coronary intervention (PCI). Multiple factors are said to precipitate ST, related to the patient's clinical comorbidities, lesion characteristics, operative technique, and post-procedural care. The older-generation stents were thought to be involved in early ST. Though the new generation of drug-eluting stents decreases the incidence of early and late ST, patients are still at risk of very late stent thrombosis (VLST). Objective To evaluate the frequency, risk factors, and outcomes of definite ST in developing and resource-constrained countries like Pakistan, where PCIs, including primary PCI, complex PCI, and PCI in high-risk populations, are performed routinely. Methods This observational cross-sectional study included all patients who underwent primary and complex high PCI between 2012 and 2017 at TABBA Heart Institute (THI), Karachi, Pakistan. Results We included a total of 6587 patients in our study, and among the enrolled sample size, 22 (0.33%) had definite ST. Acute stent thrombosis (AST) was found in seven patients, sub-acute stent thrombosis (SAST) in 10, late stent thrombosis (LST) in two, and VLST were observed in three patients. The basic characteristics of our study ST population were as follows: mean age was 58 years, 95.5% were male, 4.5% were female, nine patients (40%) had diabetes mellitus, 15 patients (68%) had hypertension, 11 (50%) had dyslipidemia, and four patients were smokers (18%). Conclusion The frequency, risk factors, and rate of mortality of definite ST in the Pakistani population who underwent primary and complex high-risk PCI reflect nearly equal statistics observed in other studies. As seen in other international studies, the incidence rate of VLST was higher in our population.

Frequency and Predictors of Radial Artery Occlusion in Patients Undergoing Percutaneous Coronary Intervention.

Background and objective Transradial access (TRA) has become the preferred route for percutaneous coronary interventions (PCI), and this site is often a chink in the armor for staged PCI. In this study, we aimed to evaluate the incidence and predictors of radial artery occlusion (RAO) after TRA. Methods We conducted a retrospective study involving 1,307 patients who underwent PCI at the Tabba Heart Institute (THI) in Karachi, Pakistan from August 2018 to June 2019. TR band was used for hemostasis after PCI. Results The primary outcome of our study was RAO, which was observed in 11.3% of the study subjects. On multivariate analysis, female gender [odds ratio (OR): 1.79, 95% CI: 1.21-2.64], cardiovascular instability (OR: 2.5, 95% CI: 1.22-5.11), dyslipidemia (OR: 0.61, 95% CI: 0.4-0.92), and a higher number of diseased vessels were found to be predictors of RAO (p=0.004). Conclusion RAO is often an asymptomatic complication of TRA. To ensure radial artery patency, a carefully thought-out management plan and follow-up must be devised for high-risk patients.

Rationale and design for comparison of non-compliant balloon with drug-coating balloon angioplasty for side branch after provisional stenting for patients with true coronary bifurcation lesions: a prospective, multicentre and randomised DCB-BIF trial.

INTRODUCTION: Provisional stenting using drug-eluting stent is effective for simple coronary bifurcation lesions. Kissing balloon inflation using conventional non-compliant balloon is the primary treatment of side branch (SB) after main vessel (MV) stenting. Drug-coating balloon (DCB) is reported to be associated with less frequent clinical events in in-stent restenosis and small vessel disease. The importance of DCB in bifurcation treatment is understudied. Accordingly, this trial is designed to investigate the superiority of DCB to non-compliant balloon angioplasty for SB after provisional stenting in patients with true coronary bifurcation lesions. METHODS AND ANALYSIS: The DCB-BIF trial is a prospective, multicentre, randomised, superiority trial including 784 patients with true coronary bifurcation lesions. Patients will be randomised in a 1:1 fashion to receive either DCB or non-compliant balloon angioplasty if SB diameter stenosis >70% after MV stenting. The primary endpoint is the composite of major adverse cardiac event at the 1-year follow-up, including cardiac death, myocardial infarction (MI) or clinically driven target lesion revascularisation. The major secondary endpoints include all-cause death, periprocedural MI, spontaneous MI, clinically driven target vessel revascularisation, in-stent restenosis, stroke and individual component of the primary endpoint. The safety endpoint is the risk of stent thrombosis. ETHICS AND DISSEMINATION: The study protocol and informed consent have been reviewed and approved by the Institutional Review Board of all participating centres. The written informed consent for participation in the trial will be obtained from all participants. The results of this study will be published in a peer-reviewed journal and disseminated at conferences. TRIAL REGISTRATION NUMBER: NCT04242134.

Outcomes and complications of percutaneous device closure in adults with secundum atrial septal defect.

OBJECTIVE: To assess immediate outcome and complications of Amplatzer septal occluder percutaneous device for closure of secundum atrial septal defect in adults, and to determine regression in right ventricular size, reduced pulmonary arterial systolic pressure and incidence of device embolization at follow-up. METHODS: The single-cohort, ambi-directional, observational study was conducted at the Tabba Heart Institute, Karachi, from January 2013 to July 2018, and comprised patients admitted consecutively for percutaneous atrial septal defect closure. Pre-closure trans-oesophageal echocardiogram was performed in all cases to ensure adequacy of defect margins necessary for device stability. Immediate procedure success and complications were determined by trans-oesophageal echocardiogram, while transthoracic echo was done on follow-up. Data was analysed using SPSS 21. RESULTS: Of the 64 patients, 41(71.9%) were females. The overall mean age was 36.6±14 years. Median size of atrial septal defect was 21mm (interquartile range: 17-26mm). Immediate success was observed in 59(92.2%) patients, and there were 5(8%) acute device embolization events. Small residual atrial septal defect was found in 4(6.3%) cases. On 20-month follow-up, 54(84.4%) patients showed improved symptoms. Repeat transthoracic echo was performed in 39(60.1%) cases, and there were no late embolic events or residual atrial septal defect. Right ventricular size normalized in 34(89.5%) cases, mean pulmonary arterial systolic pressure reduced significantly compared to pre-closure measurement (p<0.001). CONCLUSIONS: Percutaneous atrial septal defect closure was found to be safe and effective in adults with secundum atrial septal defect. Timely closure resulted in improved symptoms, right ventricular remodelling and reduced pulmonary arterial systolic pressure at intermediate-term follow-up.

Impact of Delayed Pain to Needle and Variable Door to Needle Time On In-Hospital Complications in Patients With ST-Elevation Myocardial Infarction Who Underwent Thrombolysis: A Single-Center Experience.

Background Myocardial infarction is a life-threatening event, and timely intervention is essential to improve patient outcomes and mortality. Previous studies have shown that the time to thrombolysis should be less than 30 minutes of the patient's arrival at the emergency room. Pain-to-needle time is a time from onset of chest pain to the initiation of thrombolysis, and door-to-needle time is a time between arrival to the emergency room to initiation of thrombolytic treatment. Ideally, the target for door-to-needle time should be less than 30 minutes; however, it is unclear if the door-to-needle time has a significant impact on patients presenting later than three hours from the onset of pain. As many of the previous studies were conducted in first-world countries, with established emergency medical services (EMS) systems and pre-hospital ST-elevation myocardial infarction (STEMI) triages and protocols, the data is not completely generalizable to developing countries. We, therefore, looked for the impact of the shorter and longer door-to-needle times on patient outcomes who presented to the emergency room (ER) with delayed pain-to-needle times (more than three hours of pain onset).  Objective To determine the impact of delayed pain-to-needle time (PNT) with variable door-to-needle time (DNT) on in-hospital complications (post-infarct angina, heart failure, left ventricular dysfunction, and death) in patients with ST-elevation myocardial infarction (STEMI) who underwent thrombolysis. Methods and results A total of 300 STEMI patients who underwent thrombolysis within 12 hours of symptoms onset were included, which were divided into two groups based on PNT. These groups were further divided into subgroups based on DNT. The primary outcome was in-hospital complications between the two groups and between subgroups within each group. The pain-to-needle time was ≤3 hours in 73 (24.3%) patients and >3 hours in 227 (75.7%) patients. In-hospital complications were higher in group II with PNT >3 hours (p <0.05). On subgroup analysis, in-hospital complications were higher with longer door-to-needle time in group II (p<0.05); however, there was no difference in complications among group I. Conclusion Our study is consistent with the fact that shorter door-to-needle time, even in patients with delayed PNT (>3 hours), has a significant impact on in-hospital complications with no difference in mortality.

Heterogeneity in cardio-metabolic risk factors and atherosclerotic cardiovascular disease among Asian groups in the United States.

OBJECTIVE: The Asian American population in the U.S. comprises various, ethnically diverse subgroups. Traditionally, this population has been studied as a single, aggregated group, potentially masking differences in risk among subgroups. Analyses using disaggregated data can help better characterize the health needs of different Asian subpopulations and inform targeted, effective public health interventions. We assessed the prevalence of cardiovascular disease (CVD) risk factors and atherosclerotic CVD (ASCVD) and their associations with socioeconomic factors among Chinese, Asian Indian, Filipino and Other Asian subjects, compared with non-Hispanic White (NHW) subjects in the U.S. METHODS: : Cross-sectional study using data from 298,286 adults from the National Health Interview Survey (NHIS) from 2007 to 2018. We utilized chi-squared tests to compare characteristics across subgroups. Weighted proportions and unadjusted and adjusted logistic regression models were utilized to examine the associations between Asian subgroups, self-reported CVD risk factors and self-reported ASCVD, as well as between socioeconomic factors within each Asian subgroup. RESULTS: : Asian Indian subjects had the highest prevalence of diabetes (12.5%), while Filipino subjects had the highest prevalence of hyperlipidemia (27.7%), hypertension (29.8%) and obesity (19.8%). Despite this, the prevalence of self-reported ASCVD was lower in all Asian groups compared with NHWs. Chinese subjects had the lowest odds of having each of the CVD risk factors assessed. CONCLUSION: : We found considerable heterogeneity in the distribution of risk factors as well as ASCVD among Asian subgroups in the US. Compared with health system or community-based reports, the prevalence of risk factors and ASCVD may be underestimated in some Asian NHIS subgroups. There is an urgent need for efforts to improve recruitment of Asian participants of heterogeneous socioeconomic backgrounds in national surveys, as well as to perform a thorough assessment of risk factors and disease in this population, not relying solely on self-report.

Multicoagulant resistant pseudothrombocytopenia.

Pseudo thrombocytopenia is the estimation of low platelet counts by a Haematology analyzer despite of shortage in platelets. EDTA-induced pseudo thrombocytopenia, commonly seen in clinical practice, occurs mainly due to the anti-platelet antibodies. Pseudo thrombocytopenia is seen in normal healthy individuals and other disorders like cardiovascular, liver, autoimmune diseases and malignancy. We are presenting a case of multi-coagulant resistant dependent thrombocytopenia. The purpose of this letter is to review approaches to pseudo thrombocytopenia. The case has coagulant resistant dependent thrombocytopenia in association with Anasarca and was a known case of cardiomyopathy with severely dilated left atrium, left ventricle and right atrium.

Contemporary outcomes studies to identify and mitigate the risk in patients with premature cardiovascular disease.

Introduction: As the leading cause of death globally, atherosclerotic cardiovascular disease (ASCVD) carries substantial cost burden for patients and the healthcare system. Although overall mortality rates have recently decreased in certain groups, such improvements were not observed in younger ASCVD patients. This review focuses on premature ASCVD and explores risk factors affecting this younger cohort of patients.Areas covered: We performed a literature search for studies assessing premature ASCVD, defined as ischemic heart disease (IHD), ischemic cerebrovascular disease (ICVD), or peripheral arterial disease (PAD) occurring in men aged ≤55 years and women aged ≤65 years.Expert opinion: Premature ASCVD patients often suffer from multiple traditional cardiovascular risk factors, in addition to genetic predisposition or unique non-traditional features, such as substance abuse and chronic inflammatory conditions. Consequently, identification and management of at-risk individuals pose a great challenge for clinicians. In this younger patient cohort, control of traditional risk factors, optimization of primary and secondary prevention therapies, and lifestyle modifications are imperative to saving potential disability-adjusted life years and other costs associated with premature atherosclerosis.

Frequency and distribution of angiographically occluded coronary artery and in-hospital outcome of patients with Non ST elevation myocardial infarction.

OBJECTIVE: To calculate the frequency and distribution of occluded coronary artery in patients with recent non-ST elevation myocardial infarction undergoing coronary angiography, and to compare major adverse cardiovascular events during hospitalisation with patients suffering from non-occluded coronary artery. METHODS: The cross-sectional analytical study was conducted at Tabba Heart Institute, Karachi, from July2013 to March 2014. Patients of both gender and all ages undergoing angiography with non-ST elevation myocardial infarction were included. Data on patient demographics, angiographic findings and in-hospital complications was collected. Frequency of occluded vessels and their distribution was reported. Multivariate logistic regression modelling was used to examine variables associated with an occluded coronary artery in non-ST elevation myocardial infarction. Major adverse cardiovascular events were compared between patients of occluded and non-occluded coronary aetery. A two sided p-value of < 0.05 was taken as significant. RESULTS: In 703 patients studied, occluded coronary artery was present in 277(39%). Predictors of having an occluded coronary artery were increasing age (57.6±11.2 vs. 60.0±10.0; p: 0.03) and low left ventricular ejection fraction (43.9±12.2 vs. 50.1±10.1; p: 0.000). There was no significant difference in terms of major adverse cardiovascular events in patients with occluded and non-occluded coronary arteries (Hazard Ratio: 0.53, 95% confidence interval: 0.14-1.98; p=0.33). CONCLUSIONS: Totally occluded coronary vessel is a frequent finding in non-ST elevation myocardial infarction, highlighting the need for angiography and re-vascularisation to salvage at-risk myocardium in selected patients.

Causal Assessment of Serum Urate Levels in Cardiometabolic Diseases Through a Mendelian Randomization Study.

BACKGROUND: Although epidemiological studies have reported positive associations between circulating urate levels and cardiometabolic diseases, causality remains uncertain. OBJECTIVES: Through a Mendelian randomization approach, we assessed whether serum urate levels are causally relevant in type 2 diabetes mellitus (T2DM), coronary heart disease (CHD), ischemic stroke, and heart failure (HF). METHODS: This study investigated 28 single nucleotide polymorphisms known to regulate serum urate levels in association with various vascular and nonvascular risk factors to assess pleiotropy. To limit genetic confounding, 14 single nucleotide polymorphisms exclusively associated with serum urate levels were used in a genetic risk score to assess associations with the following cardiometabolic diseases (cases/controls): T2DM (26,488/83,964), CHD (54,501/68,275), ischemic stroke (14,779/67,312), and HF (4,526/18,400). As a positive control, this study also investigated our genetic instrument in 3,151 gout cases and 68,350 controls. RESULTS: Serum urate levels, increased by 1 SD due to the genetic score, were not associated with T2DM, CHD, ischemic stroke, or HF. These results were in contrast with previous prospective studies that did observe increased risks of these 4 cardiometabolic diseases for an equivalent increase in circulating urate levels. However, a 1 SD increase in serum urate levels due to the genetic score was associated with increased risk of gout (odds ratio: 5.84; 95% confidence interval: 4.56 to 7.49), which was directionally consistent with previous observations. CONCLUSIONS: Evidence from this study does not support a causal role of circulating serum urate levels in T2DM, CHD, ischemic stroke, or HF. Decreasing serum urate levels may not translate into risk reductions for cardiometabolic conditions.
