Investigating factors associated with the prevalence of IHD among uncontrolled diabetic patients

Abstract Funding Acknowledgements Type of funding sources: Other. Main funding source(s): Monash University Malaysia Background Ischaemic Heart Disease (IHD) is the leading cause of death in Malaysia (1), and there is an increasing trend in mortality due to IHD from 15.2% in 2019 to 17.2% in 2020 (2). IHD is one of the NCDs, estimated to have an RM100.79 billion burden of disease cost (health burden resulting from disability and loss of healthy life years), equivalent to 7% of GDP (3). Diabetes mellitus (DM) is known to be one of the risk factors for IHD. Purpose This study aimed to investigate the risk factors associated with the prevalence of IHD in uncontrolled diabetic patients. Besides, these characteristics were also compared among the duration of uncontrolled DM (<10 years vs. ≥10 years) Materials and Methods A single-center, cross-sectional study was conducted in a cardio referral center using Electronic Medical Record from 1 January 2020 to 31 December 2020. Adult patients aged ≥ 18 years old with uncontrolled type 2 diabetes mellitus (defined as HbA1c ≥7%) had their medical records examined for IHD upon first contact with the Diabetes Mellitus Therapy Adherence Clinic (DMTAC) pharmacist. Results A total of 495 participants with uncontrolled diabetes were included in the final analysis. The mean age and HbA1c in the overall cohort were 52.2 (10.9) years and 10.5%, respectively, with 59.4% (n=294) of them having <10 years of underlying diabetes. The majority were obese (64.8%) and had underlying hypertension (78.4%) and hyperlipidemia (78.4%). The prevalence of ischemic heart disease (IHD) among the overall cohort was 19.0% (n=94). Patients with longer underlying diabetes (≥10 years) were significantly older [mean age 56.8 (8.4) vs. 49.0 (11.4), p=<0.001], drinks alcohol [12.0% vs. 6.0%; p=0.022], had underlying hypertension [86.6 vs. 72.8; p=<0.001] and more comorbidities [mean 1.7 (0.55) vs. 1.5 (0.65); p=<0.001] compared to those with <10 years respectively. Independent predictors of IHD events were age 40-49 [OR 5.1 (95% CI 1.1-23.3); p=0.038], 50-59 [OR 5.36 (1.2-23.7); p=0.027] and ≥60 [OR 7.1 (1.6-32.3); p=0.011], alcohol use [OR 2.4 (1.1-5.1); p=0.023], ≥10 years of uncontrolled diabetes [OR 2.0 (1.2-3.3); P=0.007], and underlying hypertension [OR 2.6 (1.2-5.8); p=0.016]. Conclusion IHD has an indirect impact on social and economic development due to the high burden of the disease cost. In our study, older age, alcohol use, prolonged uncontrolled diabetes, and underlying hypertension seem to be associated with the prevalence of IHD complications. With the understanding of the recent outlook on diabetes, health education for the targeted population may negate this complication.

Development and validation of ischemic heart disease and stroke prognostic models using large-scale real-world data from Japan.

Previous cardiovascular risk prediction models in Japan have utilized prospective cohort studies with concise data. As the health information including health check-up records and administrative claims becomes digitalized and publicly available, application of large datasets based on such real-world data can achieve prediction accuracy and support social implementation of cardiovascular disease risk prediction models in preventive and clinical practice. In this study, classical regression and machine learning methods were explored to develop ischemic heart disease (IHD) and stroke prognostic models using real-world data. IQVIA Japan Claims Database was searched to include 691,160 individuals (predominantly corporate employees and their families working in secondary and tertiary industries) with at least one annual health check-up record during the identification period (April 2013-December 2018). The primary outcome of the study was the first recorded IHD or stroke event. Predictors were annual health check-up records at the index year-month, comprising demographic characteristics, laboratory tests, and questionnaire features. Four prediction models (Cox, Elnet-Cox, XGBoost, and Ensemble) were assessed in the present study to develop a cardiovascular disease risk prediction model for Japan. The analysis cohort consisted of 572,971 invididuals. All prediction models showed similarly good performance. The Harrell's C-index was close to 0.9 for all IHD models, and above 0.7 for stroke models. In IHD models, age, sex, high-density lipoprotein, low-density lipoprotein, cholesterol, and systolic blood pressure had higher importance, while in stroke models systolic blood pressure and age had higher importance. Our study analyzed classical regression and machine learning algorithms to develop cardiovascular disease risk prediction models for IHD and stroke in Japan that can be applied to practical use in a large population with predictive accuracy.

Addition of Risk-enhancing Factors Improves Risk Assessment of Atherosclerotic Cardiovascular Disease in Middle-aged and Older Chinese Adults: Findings from the Chinese Multi-provincial Cohort Study

Objective: This study aimed to examine whether integrating risk-enhancing factors into the Chinese Society of Cardiology-recommended clinical risk assessment tool (i.e., the CSC model) for atherosclerotic cardiovascular disease (ASCVD) might improve 10-year ASCVD risk stratification in Chinese adults. Methods: A total of 4910 Chinese participants who were 50–79 years of age and free of cardiovascular disease in the 2007–2008 Survey from the Chinese Multi-provincial Cohort Study were included. We assessed the updated model’s clinical utility (i.e., Harrell’s C-index and net reclassification improvement [NRI]) by adding risk-enhancing factors individually or the number of risk-enhancing factors to the CSC model, for all individuals or those at intermediate risk. Risk-enhancing factors, including a family history of CVD, triglycerides ≥2.3 mmol/L, high-sensitivity C-reactive protein ≥2 mg/L, Lipoprotein (a) ≥50 mg/dL, non-high-density lipoprotein cholesterol ≥4.9 mmol/L, overweight/obesity, and central obesity, were evaluated. ASCVD events were defined as a composite endpoint comprising ischemic stroke and acute coronary heart disease events (including nonfatal acute myocardial infarction and all coronary deaths). Results: During a median 10-year follow-up, 449 (9.1%) ASCVD events were recorded. Addition of ≥2 risk-enhancing factors to the CSC model yielded a significant improvement in the C-index (1.0%, 95% confidence interval [CI]: 0.2–1.7%) and a modest improvement in the NRI (2.0%, 95% CI: −1.2–5.4%) in the total population. For intermediate-risk individuals, particularly individuals at high risk of developing ASCVD, significant improvements in NRI were observed after adding ≥2 risk-enhancing factors (17.4%, 95% CI: 5.6–28.5%) to the CSC model. Conclusions: Addition of ≥2 risk-enhancing factors refined 10-year ASCVD risk stratification, particularly for intermediate-risk individuals, supporting their potential in helping tailor targeted interventions in clinical practice.

Global, regional and national estimates of influenza-attributable ischemic heart disease mortality.

Influenza virus infection is associated with incident ischemic heart disease (IHD) events. Here, we estimate the global, regional, and national IHD mortality burden attributable to influenza. We used vital registration data from deaths in adults ≥50 years (13.2 million IHD deaths as underlying cause) to assess the relationship between influenza activity and IHD mortality in a non-linear meta-regression framework from 2010 to 2019. This derived relationship was then used to estimate the global influenza attributable IHD mortality. We estimated the population attributable fraction (PAF) of influenza for IHD deaths based on the relative risk associated with a given level of weekly influenza test positivity rate and multiplied PAFs by IHD mortality from the Global Burden of Disease study. Influenza activity was associated with increased risk of IHD mortality across all countries analyzed. The mean PAF of influenza for IHD mortality was 3.9% (95% uncertainty interval [UI] 2.5-5.3%), ranging from <1% to 10%, depending on country and year. Globally, 299,858 IHD deaths (95% UI 191,216-406,809) in adults ≥50 years could be attributed to influenza, with the highest rates per 100,000 population in the Central Europe, Eastern Europe and Central Asia Region (32.3; 95% UI 20.6-43.8), and in the North Africa and Middle East Region (26.7; 95% UI 17-36.2). Influenza may contribute substantially to the burden of IHD. Our results suggest that if there were no influenza, an average of 4% of IHD deaths globally would not occur.

Cardiovascular Manifestations of Long COVID: A Review.

The acute phase of severe acute respiratory syndrome coronavirus 2 [coronavirus disease (COVID)] infection has many well-documented cardiovascular manifestations, however, the long-term sequelae are less understood. In this focused review, we explore the risk factors, character, and rates of cardiovascular events in patients with Long COVID, which is defined as symptoms occurring more than 4 weeks following initial infection. Research has identified increased rates of cerebrovascular disease, dysrhythmias, ischemic and inflammatory heart disease, cardiopulmonary symptoms, and thrombotic events among those with Long COVID, though the risk rates and potential mechanisms behind each cardiovascular event vary. Finally, we discuss the current gaps in the literature as well as how COVID compares to other viral infections when it comes to causing long-term cardiovascular sequelae.

Tuberculosis and the Risk of Ischemic Heart Disease: A Nationwide Cohort Study.

Little is known about the risk of ischemic heart disease (IHD) in tuberculosis (TB) survivors. We performed a population-based retrospective cohort study using the Korean National Health Insurance Service database. TB survivors (n = 60 602) and their 1:1 age- and sex-matched controls (n = 60 602) were enrolled. Eligible participants were followed up from 1 year after their TB diagnosis to the date of an IHD event, date of death, or the end of the study period (31 December 2018), whichever came first. The risk of IHD was estimated using a Cox proportional hazards regression, and stratified analyses were performed for related factors. Among IHD events, we additionally analyzed for myocardial infarction (MI). During a median of 3.9 years of follow-up, 2.7% of TB survivors (1633/60 602) and 2.0% of the matched controls (1228/60 602) developed IHD, and 0.6% of TB patients (341/60 602) and 0.4% of the matched controls (223/60 602) developed MI. The overall risk of developing IHD and MI was higher in TB patients (adjusted hazard ratio [aHR] 1.21, 95% confidence interval [CI]: 1.12-1.32 for IHD and aHR 1.48, 95% CI: 1.23-1.78 for MI) than in the matched controls. Stratified analyses showed that TB survivors have an increased risk of IHD and MI regardless of income, place of residence, smoking status, alcohol consumption, physical activity, body mass index, and Charlson comorbidity index. TB survivors have a higher risk of IHD than matched controls. Strategies are needed to reduce the burden of IHD in TB survivors.

EE84 Cost of Follow-Up After an Ischemic Heart Disease Event in Patients With Atherosclerotic Cardiovascular Disease in Spain: Results From the Reality Study

Background: Ischemic heart disease angina and acute myocardial infarction (AMI) are one of the main causes of morbidity and mortality in developed countries and entails a high resources consumption and costs for health systems. The risk of suffering future CV events and the consequent consumption of resources is increased in those patients who have suffered a previous AMI.

Abstract 11895: Decreased Heart Rate Variability Associated With Hopelessness in Patients With Ischemic Heart Disease

Hopelessness, a negative outlook and sense of helplessness toward the future, is present in 27-52% of patients with ischemic heart disease (IHD) and is associated with increased morbidity and mortality. Physiologic dynamics of hopelessness in patients with IHD are largely unknown. Purpose : To examine how stress adaptation, measured by high frequency (HF) heart rate variability (HRV), following an IHD event may be associated with hopelessness. Subgroup differences focusing on characteristics known to be associated with hopelessness and/or HRV will also be examined (i.e., IHD event, marital status, sex). Hypothesis : Decreased HF HRV will be associated with greater levels of hopelessness. Methods : Participants were enrolled while hospitalized for an IHD event after being identified as appropriate for HRV analysis (n=69). Two weeks after hospital discharge, participants wore a Polar H7 heart rate monitor for 10 minutes while supine for HRV data collection. A demographic questionnaire and State-Trait Hopelessness Scale were then completed. From the 10-minutes of HRV data, a 5-minute HRV segment with the least amount of artifact (&lt;5%) was used for analysis. HRV data was log transformed to account for non-normality. Linear regression was used to assess the relationship between HRV and state hopelessness. Results : There was a moderate negative correlation between HF HRV and state hopelessness (r= -0.35, p=0.004). This remained significant in multivariable regression models when controlling for history of depression and factors known to influence HRV (i.e., time of day, age, and smoking status). No sex differences (Cohen’s d=-0.04, p=0.78) were observed for HF HRV, but persons who underwent bypass surgery had lower HF compared to those that did not (Cohen’s d=0.63, p=0.04). Due to high correlation with HF and root mean square of successive differences between normal heartbeats (rMSSD) and SD1 (r=0.85), patterns of association with hopelessness and those variables were similar throughout. Conclusion : Decreased HF was moderately correlated with increased state hopelessness following an IHD event. Assessing HRV in patients following an IHD event could provide promising evidence of a biomarker to assist in identifying patients at risk for hopelessness.

Abstract 11275: Comorbidity Score is Positively Associated With Hopelessness in Adults With Ischemic Heart Disease

Introduction: Comorbidities are associated with increased risk of mortality in adults with ischemic heart disease (IHD). Hopelessness, a negative outlook and sense of helplessness towards the future, is identified in 27–52% of patients with IHD and associated with a 3.4 times increased risk of mortality or nonfatal myocardial infarction. The relationship between comorbidities and hopelessness in adults with IHD is unknown. Hypothesis: A higher comorbidity score is positively associated with state and trait hopelessness levels in adults hospitalized with an IHD event. Methods: Participants completed the State-Trait Hopelessness Scale and reported basic demographics. Continuous (range 0-14) and categorical scores for the Charlson Comorbidity Index (CCI) were generated based on patient medical records. Results: Participants (n=132) were typical of the U.S. IHD population except for race/ethnicity. Ninety-one were male (68.4%), mean age was 62.6 years (SD= 9.6), and 97% were non-Latinx White (3.0%). The mean CCI was 3.5 (SD=2.2), with 36.4% having a score of 1-2 (mild), 41.2% with a score of 3-4 (moderate) and 22.7% with a score of ≥5 (severe). The CCI was positively associated with both state and trait hopelessness in unadjusted and adjusted (demographics, medical history, and exercise history) analyses (unadjusted: r=0.26, p=0.002 (state); r=0.23, p=0.009 (trait) and adjusted: r=0.22, p=0.008 (state); r=0.18, p=0.052 (trait)). Components of the CCI showing the strongest relationships with higher levels of hopelessness were cerebrovascular accident (n=8), organ damage from diabetes (n=17), COPD (n=24), and renal failure (n=9). Interaction terms were evaluated and there was no evidence that the relationship between the CCI and hopelessness differed by age, gender, education level, or cardiac intervention type. Conclusions: Our hypothesis of a positive association between comorbidity score and state and trait hopelessness was confirmed. Knowledge of hopelessness in IHD patients with comorbidities is important for health care professionals in acute care and outpatient settings so at-risk patients can be identified and appropirate interventions employed. Future work should be conducted in larger, more heterogeneous samples.

Intake of dietary flavonoids and incidence of ischemic heart disease in the Danish Diet, Cancer, and Health cohort

Background/ObjectivesFew studies have investigated the association between dietary flavonoid intake, including all major subclasses, and the long-term risk of ischemic heart disease (IHD). We examined whether dietary flavonoid intake associated with IHD incidence, assessing the possible modifying role of sex and smoking, in participants from the Danish Diet, Cancer, and Health study.Subjects/MethodsIn a cohort study design, 54,496 adults (46.8% male), aged 50–64 years, without a history of IHD, were followed for up to 23 years. Habitual dietary flavonoid intake was estimated from food frequency questionnaires using Phenol-Explorer. Incident cases of IHD were identified within Danish nationwide health registries. Restricted cubic splines in Cox proportional hazards models were used to examine associations between flavonoid intake and IHD risk.ResultsDuring follow-up, 5560 IHD events were recorded. No overall association was seen between total flavonoid intake, nor any subclass, and IHD, following adjustment for demographics, lifestyle, and dietary confounders. Stratified by sex and smoking status, higher intakes of specific subclasses associated with lower IHD risk among ever-smokers [Q5 vs. Q1 flavonols HR (95% CI): 0.90 (0.82, 0.99); flavanol oligo+polymers: 0.88 (0.80, 0.97)], but not among never-smokers, nor either sex specifically.ConclusionsWhile we did not find clear evidence that higher habitual dietary flavonoid intake was associated with lower IHD risk, these results do not exclude the possibility that certain subclasses may have a protective role in prevention of IHD among population sub-groups; this was evident among smokers, who are at a higher risk of atherosclerosis.

Decreasing albumin within normal range is associated with increased likelihood of ischemic heart disease

Abstract Background Albumin (ALB) is a known biomarker of frailty, and cardiovascular disease and frailty are interdependent. Epidemiological evidence demonstrates that low serum albumin levels are linked to events of ischemic heart disease (IHD), venous thromboembolism, heart failure, atrial fibrillation, and stroke. Purpose We aimed to investigate the association of variations in ALB levels that are within normal range with IHD events among apparently healthy adults. Methods A case-control retrospective study of self-referred adults participating in an executive screening program between 2002 and 2017. All subjects were free of IHD and diabetes at baseline and had their ALB documented in each visit. Only subjects with at least two ALB measurements and whose ALB levels were within the normal range at all visits were included. Relationships between ALB trend and occurrence of IHD (acute coronary syndrome or percutaneous coronary intervention) within 2 years from the last visit were investigated. Results The final study cohort included 16,386 subjects. Median age was 53 (IQR 45–60), 11,461 (70%) were men. Analysis included a total of 99,127 visits. Median number of visits per subject was 5 (IQR 3–9, median inter-visit time 1.02 years) and median ALB level was 4.4 (IQR 4.2–4.6). IHD within 2 years was diagnosed in 545 (3%) subjects. Of those, only 36 were female and they tended to have lower variations in ALB throughout the years. Hence, we conducted an analysis of the 509 males only, and created an equal-size age-matched cohort of IHD-free subjects. Our analysis demonstrated a progressive and significant decrease in ALB levels among IHD cases, but not among controls (mean decrease of 0.021 g/DL vs. 0.004 g/DL per year, p&amp;lt;0.01; OR [CI] = 0.82 [0.72–0.93]; Figure 1). Similar results were found among subjects with at least 3 or 4 visits (0.015 g/DL vs. 0.006 g/DL per year, p=0.027, and 0.009 g/DL vs. 0.003 g/DL per year, p=0.045, respectively). Conclusions Kinetics of ALB within the normal range can identify men at risk for IHD in preventive healthcare screening programs. Funding Acknowledgement Type of funding sources: None.

Risk of Ischemic Heart Disease Associated with Primary Dysmenorrhea: A Population-Based Retrospective Cohort Study.

The awareness on ischemic heart disease (IHD) in women with dysmenorrhea is insufficient. We utilized the National Health Insurance Research Database (NHIRD) of Taiwan to evaluate this relationship. From the claims data, we established a cohort of women aged 15–50 years with primary dysmenorrhea diagnosed from 2000 to 2008 (n = 18,455) and a comparison cohort (n = 36,910) without dysmenorrhea, frequency matched by age and diagnosis date. Both cohorts were followed until the end of 2013 to assess IHD events. With 75% of study population aged 15–29 years, the incidence of IHD was greater in the dysmenorrheal cohort than in the comparison cohort (1.93 versus 1.18 per 10,000 person-years), with an adjusted hazard ratio of 1.60 (95% confidence interval [CI] = 1.38–1.85). The incidence increased with age and the rate of increase was greater in the dysmenorrheal cohort than the comparison cohort. Nested case-control analysis in the dysmenorrhea cohort showed that IHD risk was also associated with hypertension and arrhythmia, with adjusted odds ratios of 2.50 (95% CI = 1.64–3.81) and 3.30 (95% CI = 2.25–4.86), respectively. Women with dysmenorrhea are at a higher risk of developing IHD, particularly for older patients and patients with comorbidity.

Reduction of Cardiovascular Events and Related Healthcare Expenditures through Achieving Population-Level Targets of Dietary Salt Intake in Japan: A Simulation Model Based on the National Health and Nutrition Survey.

Reducing population dietary salt intake is expected to help prevent cardiovascular disease and thus constrain increasing national healthcare expenditures in Japan’s super-aged society. We aimed to estimate the impact of achieving global and national salt-reduction targets (8, <6, and <5 grams/day) on cardiovascular events and national healthcare spending in Japan. Using published data including mean salt intake and systolic blood pressure from the 2019 National Health and Nutrition Survey, we developed a Markov model of a closed cohort of adults aged 40–79 years in 2019 (n = 66,955,000) transitioning among six health states based on the disease course of ischemic heart disease (IHD) and stroke. If mean salt intake were to remain at 2019 levels over 10 years, cumulative incident cases in the cohort would be approximately 2.0 million for IHD and 2.6 million for stroke, costing USD 61.6 billion for IHD and USD 104.6 billion for stroke. Compared with the status quo, reducing mean salt intake towards the targets over 10 years would avert 1–3% of IHD and stroke events and save up to 2% of related national healthcare costs. Attaining dietary salt-reduction goals among adults would yield moderate health economic benefits in Japan.

Lipoprotein(a) and SARS-CoV-2 infections: Risk for ischemic heart disease and thromboembolic events

Background and Aims : SARS-CoV-2 positive patients show high frequency of thromboembolic complications. Comorbidities like ischemic heart disease (IHD) associate with worse outcome. Since lipoprotein(a) [Lp(a)] is a strong risk factor for IHD and has possibly thrombogenic properties, we investigated in UK Biobank whether SARS-CoV-2 infections alter the Lp(a)-driven risk for IHD and thromboembolic events.

Association between genetic predisposition to childhood obesity and the risk of adult ischemic heart disease in China

Objective: To examine the associations of childhood obesity, assessed by genetic variations of childhood body mass index (BMI), with the risk of adult ischemic heart disease (IHD) and major coronary event (MCE). Methods: More than 69 000 participants from the China Kadoorie Biobank were genotyped. After excluding those with coronary heart disease, stroke, or cancer at baseline, a total of 64 454 participants were included in this study. Based on genome-wide significant single nucleotide polymorphisms (SNPs), childhood BMI genetic risk score were constructed for every participant and divided into quintiles, with the lowest quintile as the low genetic risk group and the highest quintile as the high genetic risk group. Cox proportional hazards regression models were used to estimate the association between genetic predisposition to childhood obesity and the risk of ischemic heart disease. Results: During a median of 10.7 years of follow-up, 7 073 incident cases of IHD and 1 845 cases of MCE were documented. After adjusting for sex, age, region, and the first ten genetic principal components, the HRs (95%CIs) for IHD and MCE in the high genetic risk group were 1.10 (1.02-1.18) and 1.10 (0.95-1.27), compared with the low genetic risk group. IHD risk increased by 4% (2%-6%) for each one standard deviation increase in genetic risk score (trend P=0.001). After further adjustment for baseline BMI, the differences between genetic risk groups were not statistically significant, but there was still a linear trend between genetic risk score and IHD risk (trend P=0.019). Conclusions: IHD risk increased with genetic predisposition to childhood obesity, suggesting that childhood obesity is an important risk factor for the development of IHD in China. As an easily identifiable feature, changes of childhood BMI should be monitored regularly to realize early intervention of IHD in adults.

Trends in the occurrence of ischaemic heart disease over time in rheumatoid arthritis: 1821 patients from 1972 to 2017

Objective To evaluate trends of acute myocardial infarction (AMI) and ischaemic heart disease (IHD) in rheumatoid arthritis (RA) patients compared with the general population over time. Method We performed a retrospective cohort study of 1821 RA patients diagnosed from 1972 to 2013. Aggregated counts of the total population of the same county (Hordaland, Norway) and period were used for comparison. Information on AMI and IHD events was obtained from hospital patient administrative systems or cardiovascular registries. We estimated incidence rates and excess of events [standardized event ratio (SER) with 95% confidence interval (CI)] compared with the general population by Poisson regression. Results There was an average annual decline of 1.6% in age- and gender-adjusted AMI incidence rates from 1972 to 2017 (p < 0.035). The difference in events (excess events) in RA patients compared with the general population declined on average by 1.3% per year for AMI and by 2.3% for IHD from 1972 to 2014. There were no significant excess AMI (SER 1.05, 95% CI 0.82–1.35) or IHD events (SER 1.02, 95% CI 0.89–1.16) for RA patients diagnosed after 1998 compared with the general population. Conclusion Incidence rates and excess events of AMI and IHD in RA patients declined from 1972 to 2017. There were no excess AMI or IHD events in RA patients diagnosed after 1998 compared with the general population.

A Cross-Sectional Study of the Current Management of Hypertriglyceridemia.

ObjectivesTo estimate the prevalence of hypertriglyceridemia (HTG), determine the association between HTG and the risk of ischemic heart disease and major adverse cardiovascular events. Lastly, to assess the management outcomes of HTG in terms of the different drugs in the treatment plan. MethodsA retrospective, longitudinal study at a tertiary hospital was conducted. All who came in were screened. Patients with HTG (TAG [triacylglyceride] 2.3 mmol/L) in the last five years were included in the study. The data included the demographic variables, potential causes, and the methods of management. All data were recorded in a standard data collection form and analyzed by an appropriate statistical tool, using the John Macintosh Project (JMP) software version 15 (Cary, NC: SAS Institute Inc.).ResultsOf 300 patients included, 174 (58.0%) were male, with a mean age of 57.8±13.4 years. Pre-treatment, the mean triglycerides (TG) was 3.2±2.3 mmol/L, low-density lipoprotein (LDL) 2.7±1.3 mmol/L, high-density lipoprotein (HDL) 0.93±0.30 mmol/L, and the total cholesterol (TC)was 5.2±1.3 mmol/L. All the patients have prescribed a statin, 144 (48.0%) received aspirin, six (2.0%) fenofibrate, and three (1.0%) gemfibrozil. At the follow-up, the level of the TG was 2.6±1.3 mmol/L (P=0.001), LDL 2.5±1.2 mmol/L (P=0.006) and total cholesterol (TC) 4.7±1.5 mmol/L (P=0.001). Almost a third (28.2%) developed cardiac complications, five (1.6%) presented with unstable angina, six (2.0%) as non-ST segment elevation myocardial infarction (NSTEMI), three (1.0%) had ST segment elevation myocardial infarction (STEMI), and 19 (6.3%) had heart failure. A small proportion (17.3%) had a percutaneous coronary intervention, 27 (9.0%) had single-vessel disease, 12 (4.0%) two-vessel disease, and 13 (4.3%) three-vessel disease.ConclusionsMany physicians do not pay attention to HTG in everyday practice, although HTG contributes significantly to the occurrence of coronary heart disease. In our study, the majority had mixed hyperlipidemia. One-third of patients with high triglycerides developed ischemic heart disease. The use of fenofibrate and gemfibrozil was not high. A low occurrence of pancreatitis was noted in our series.

Alcohol – The myth of cardiovascular protection

To investigate potential biases that exist in available epidemiological evidence resulting in negative associations or underestimation of cardiovascular (CV) risk associated with alcohol consumption. UK Biobank involved baseline data collection from 22 assessment centres across the United Kingdom. The cohort consisted of 333259 alcohol consumers and 21710 never drinkers. Participants were followed up for a median 6.9 years capturing incident fatal and non-fatal CV events, ischemic heart disease and cerebrovascular disease. Alcohol intake was reported as grams/week. Using never drinkers as reference, alcohol from all drink types combined (hazard ratios ranging between 0.61 and 0.74), beer/cider (0.70-0.80) and spirits combined, and all wines combined (0.66-0.77) associated with a reduced risk for all outcome measures (all CV events, ischaemic heart disease, cerebrovascular disease). In continuous analysis, alcohol captured from all drink types combined (hazard ratio, 1.08, 95% confidence interval, 1.01-1.14), and beer/cider and spirits combined (1.24, 1.17-1.31) associated with an increased risk for overall CV events, however hazard ratios were stronger for beer/cider and spirits (P<0.0001). Wine associated with a reduced risk for overall CV events (0.92, 0.86-0.98) and ischemic heart disease (0.75, 0.67-0.84). This negative relationship with overall CV events was lost after excluding ischemic heart disease events (1.00, 0.93-1.08), while the positive association of alcohol captured from beer/cider and spirits remained significant (1.30, 1.22-1.40). This positive association with overall CV events was present even when consuming less than 14 units per week. Avoiding potential biases prevents underestimation of cardiovascular risk and indicates that consuming up to 14 units per week also associated with increased CV risk in the general population.
