Patients were ≥18 years old and had ≥2 non-ancillary medical claims in the linked databases at least 30 days apart. The study was conducted in 2 stages: (1) identification of patients with ASCVD who met the definition of VHR ASCVD and a matched cohort of non-VHR ASCVD patients using the incidence density sampling (IDS) approach; (2) estimation of the occurrence of major CV events.ResultsAmong patients with ≥1 major ASCVD event (N=147,679), most qualified as VHR ASCVD (79.5%). There were 115,460 patients each in IDS-matched VHR and non-VHR ASCVD cohorts. The composite myocardial infarction/ischemic stroke event rates in the VHR and non-VHR ASCVD cohorts were 8.04 (95% confidence interval [95% CI]: 7.87-8.22) and 0.82 (95% CI: 0.77-0.88) events per 100 patient-years, respectively, during the 1-year post-index period.ConclusionsMost patients with ≥1 previous major ASCVD event treated in real-world US clinical practice qualified as VHR ASCVD. Patients with VHR ASCVD had much higher rates of major CV events versus non-VHR ASCVD patients.

Background Low‐density lipoprotein cholesterol (LDL‐C) is a risk factor for atherosclerotic cardiovascular disease (ASCVD). There are limited real‐world data on LDL‐C lowering with evolocumab in United States clinical practice. Hypothesis We assessed LDL‐C lowering during 1 year of evolocumab therapy. Methods This retrospective cohort study used linked laboratory (Prognos) and medical claims (IQVIA Dx/LRx and PharMetrics Plus®) data. Patients with a first fill for evolocumab between 7/1/2015 and 10/31/2019 (index event) and LDL‐C ≥ 70 mg/dL were included (overall cohort; N = 5897). Additionally, a patient subgroup with a recent myocardial infarction (MI) within 12 months (median 130 days) before the first evolocumab fill was identified (N = 152). Reduction from baseline LDL‐C was calculated based on the lowest LDL‐C value recorded during a 12‐month follow‐up period. Results The mean (SD) age was 65 (10) years; 61.9% of patients had ASCVD diagnoses and 70.7% of patients were in receipt of lipid‐lowering therapy. Following evolocumab treatment, changes in LDL‐C from baseline were −60% in the overall cohort (median [interquartile range (IQR)] 146 [115–180] mg/dL to 58 [36–84] mg/dL) and −65% in the recent MI subgroup (median [IQR] 137 [109–165] mg/dL to 48 [30–78] mg/dL). In the overall cohort and recent MI subgroup, 62.1% and 69.7% of patients achieved LDL‐C

Objective Our study aimed to estimate the impact of addressing modifiable risk factors on the future burden of cardiovascular diseases (CVD) in the general population and in two high-risk populations (heterozygous familial hypercholesterolemia and secondary prevention) for Turkey. Methods One model investigated the impact of reaching the World Health Organization (WHO) voluntary targets for tobacco use, hypertension, type 2 diabetes, obesity and physical inactivity in the general population. Another model estimated the impact of reducing LDL-cholesterol in two high-risk populations through increased access to effective treatment. Inputs for the models include disease and risk factor prevalence rates, a population forecast, baseline CVD event rates, and treatment effectiveness, primarily derived from the published literature. Direct costs to the public health care system and indirect costs from lost production are included, although the cost of programs and pharmacological interventions to reduce risk factors were not considered. Results The value of reaching WHO risk factor reduction targets is estimated at US$9.3 billion over the next 20 years, while the value of reducing LDL-cholesterol is estimated at up to US$8.1 billion for high-risk secondary prevention patients and US$691 million for heterozygous familial hypercholesterolemia patients. Conclusion Efforts to achieve WHO risk factor targets and further lower LDL-cholesterol through increased access to treatment for high-risk patients are projected to greatly reduce the growing clinical and economic burden of CVD in Turkey.

Physician prescription patterns for lipid lowering therapy, particularly high-intensity statins (HIS), and risk of cardiovascular events (CVE) is not well documented in the real-world clinical setting among patients hospitalized with acute myocardial infarction (AMI). We aim to examine the

We describe patient characteristics, lipid lowering therapy (LLT) use, and risks of subsequent cardiovascular events (CVE) in the 12-months following a coronary revascularization (CR). We identified patients undergoing CR between 01/2014-05/2019 (index period) in the linked IQVIA PharMetrics+/

Lipid lowering therapy, particularly use of high-intensity statins (HIS) is vital for secondary prevention of cardiovascular events, after acute myocardial infarction (AMI). However, physician prescription patterns for HIS are not well documented in the real-world setting in post-AMI patients. We

Proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) antibodies significantly reduce low-density lipoprotein cholesterol (LDL-C) in patients uncontrolled with statins and/or ezetimibe. Here we characterize the baseline cardiovascular risk profile in a subset of patients with recent

Objective This study aims to estimate the current and future burden of cardiovascular diseases (CVD) in Turkey. Methods A burden-of-disease model was developed that included inputs on population growth, prevalence, and incidence of ischemic disease (IHD) and cerebrovascular disease (CeVD), prevalence of modifiable risk factors, mortality rates, and relationship between risk factors and IHD/CeVD. Direct costs to the public health-care system and indirect costs from lost production due to premature mortality, hospitalizations, disability, and absenteeism were considered. Results We estimated that in 2016, 3.4 million Turkish adults were living with CVD, including 2.5 million affected by IHD, and 0.9 million by CeVD. This prevalence is projected to increase to 5.4 million by 2035. The economic burden of CVD was estimated at US$10.2 billion in 2016, projected to increase twofold to US$19.4 billion by 2035. Conclusion Our study confirms that the current burden of CVD is significant, and that it is projected to increase at a steep rate over the next two decades. This growing burden of disease will likely create significant pressure on the public health-care system in the form of direct health-care costs, as well as on society in the form of lost productivity.

Introduction: Dyslipidemia is an important modifiable risk factor for CVD, yet studies show that dyslipidemia is undertreated in Canada. To evaluate the management of dyslipidemia in patients at high risk for CVD (including heterozygous familial hypercholesterolemia [HeFH] and statin intolerant [SI]), we assessed lipid lowering treatment patterns, LDL-C target achievement, prevalence of CV risk factors, and the incidence of CV events, in a large Canadian cohort. Methods: We retrospectively analysed data from an open cohort of patients initiating statin therapy between 2004 and 2012 using the Southwestern Ontario primary care practice database. Inclusion criteria were diagnosis of dyslipidemia, ≥ 1 statin prescription, and ≥ 2 years statin-free baseline data. Patients were stratified into 3 CV risk levels. Here, we report the results of the high-risk patient group. Results: In a cohort of 41 733 patients who initiated statin therapy, we identified 14 607 (35%) high-risk patients. At baseline, the mean (SD) age was 54 (7) years, 51% were male, and LDL-C was 3.07 (0.41) mmol/L. On average, patients had 3 CV risk factors. Age (66% male > 45 y; 90% female > 55 y), obesity (36%, BMI > 27 kg/m 2 ), high-risk hypertension (31%), and diabetes (17%) were identified as the most important risk factors. After 1-year follow-up, 25% (n=3652) of patients who initiated statin therapy failed to reach target LDL-C. Among high-risk patients with SI (n=1294), 84% (n=1089) discontinued therapy or had a dose decrease. Six months after SI diagnosis, 51% (n=656) did not meet the LDL-C target; 74% (n=484) of these patients had their statin dose decreased or stopped or were treated with a non-statin. In the prevalent cohort (new and follow-up patients in 2012), 52% (n=64) of HeFH patients were treated for secondary prevention (ie, had experienced a prior CV event) and had LDL-C > 2.59 mmol/L, and among high-risk SI patients with LDL-C > 2.59 mmol/L, 65% (n=2304) were diagnosed with coronary heart disease and 32% (n=1132) were treated for secondary prevention. Conclusions: Despite widespread statin use, a significant therapeutic need remains for CV high-risk patients who fail to reach the recommended LDL-C target.
