Objective This study examined the association between statin usage (discontinued, reduced or continued) and two-year death following a 21% increase in the Pharmaceutical Benefits Scheme (PBS) consumer co-payment in Western Australia. Methods A retrospective observational study in Western Australia using linked administrative Commonwealth PBS data and State hospital inpatient and death data (n = 207,066) was undertaken. We explored the two-year all-cause and ischemic heart disease(IHD)/stroke-specific-death in individuals who discontinued, reduced or continued statin medication following the January 2005 PBS co-payment increase, overall, by beneficiary status (general population vs. social security recipients) and by a history of admission for ischemic heart disease or stroke. Non-cardiovascular (CVD)-related death was also considered. Results In the first six months of 2005, 3.3% discontinued, 12.5% reduced and 84.2% continued statin therapy. We found those who discontinued statins were also likely to discontinue at least two other medicines compared to those who continued therapy. There were 4,607 all-cause deaths. For IHD/stroke-specific death, there were 1,317. For all non-CVD-related death, there were 2,808 deaths during the 2-year follow-up period. Cox regression models, adjusted for demographic and clinical characteristics, showed a 39%-61% increase in the risk of all-cause death for individuals who reduced or discontinued statin medication compared to those who continued their statin medication (Discontinued: Adj HR = 1.61, 95% CI 1.40–1.85; Reduced: Adj HR = 1.39, 95% CI 1.28–1.51). For IHD/stroke-specific death, there was an increased risk of death by 28–76% (Discontinued: Adj sHR = 1.76, 95% CI 1.37–2.27; Reduced: Adj sHR = 1.28, 95% CI 1.10–1.49), and for non-CVD-related death, there was an increased risk of death by 44–57% (Discontinued: Adj sHR = 1.57, 95% CI 1.31–1.88; Reduced: Adj sHR = 1.44, 95% CI 1.30–1.60), for individuals who discontinued or reduced their statin medication compared to those who continued. Conclusions Patients who discontinued their statin therapy had a significantly increased risk of IHD and stroke death. Health professionals should be aware that large co-payment changes may be associated with patients discontinuing or reducing medicines to their health detriment. Factors that lead to such changes in patient medication-taking behaviour need to be considered and addressed at the clinical and policy levels.

Lipid and lipoprotein disorders are well known risk factors for atherosclerosis and its complications. The level of atherogenic LDL-cholesterol (LDL-C) is directly related to an increased risk of occurrence and progression of ischemic heart disease. Epidemiological and clinical studies have shown that the use of statin therapy to decrease LDL-C can significantly reduce the incidence of mortality, major coronary events and the need for revascularization procedures in the different groups of patients. The findings of a large meta-analysis conducted by the Cholesterol Treatment Trialists? (CTT) collaborators showed that every 1.0 mmol/l reduction of atherogenic LDL-C is associated with a 22% reduction in cardiovascular diseases mortality and morbidity. However, despite the impressive results of the benefits of statin therapy, the EUROASPIRE study showed that about 50% of patients with ischemic heart disease did not achieve target LDL-C levels. According to the new ESC/EAS Guidelines for the Management of Dyslipidaemias in patients with a very high cardiovascular risk, treatment goal should be to decrease LDL-C below 1.8 mmol/l or ?50% of initial values. In the majority of patients that can be achieved by statin therapy. For this reason an adequate choice of statins is of crucial importance, whereby the needed reduction in atherogenic LDL-C, after the identification of its target level based on the assessment of total cardiovascular risk, can be achieved.

Abstract Introduction The relationship between ischemic heart disease (IHD) and advanced chronic kidney disease is well established. However, there is a paucity of data regarding the long-term association in between renal function and incidence of IHD. Purpose To study the remote association between point renal function and future incidence of ischemic heart disease among healthy adults. Methods We evaluated asymptomatic self-referred adults who participated in a medical screening program. All subjects were free of IHD at baseline. Glomerular Filtration Rate (GFR) was calculated by CKD-EPI and divided into quartiles (Q1 represents the lowest quartile). Study endpoint was the development of IHD which was externally adjudicated by a physician. Mortality data were available for all subjects from national registry. Cox regression models were applied while adjusting for confounders. Results The final study population included 27,647 subjects (68% men) with a mean age of 47 years. At baseline (first screening visit), median GFR by CKD-EPI was 84 [IQR 74; 95] and 86 [IQR 74.; 101] mL/min per 1.73m2 for men women, respectively. During median follow up of 6 years [IQR 2; 12], 2,286 (8%) of subjects developed IHD, of whom 1,912 (10%) were men and 374 (4%) were women. Incident IHD was in 964 (13.98%), 705 (10.22%), 437 (6.34%) and 171 (2.48%) subjects from GFR Q1-Q4, respectively. Kaplan Meier survival analysis demonstrated a graded increased risk of IHD with decreasing eGFR quartiles (p Log rank <.001; Figure 1). Multivariate cox regression analysis revealed hazard ratio of 1.26 (95% CI 1.06, 1.51), 1.43 (95% CI 1.20, 1.70), and 1.25 (1.05, 1.50) for IHD incidence for Q1-Q3, respectively (using Q4 as reference). While considering GFR as a continuous variable, each 10 units increase in GFR was significantly associated with 4% less risk for developing IHD - HR 0.96 (95% CI 0.93–1.00, p=0.04). Conclusion Mild renal dysfunction even within the normal range is independently associated with remote risk of IHD among young apparently healthy adults. Cardiovascular screening should be considered among young patients with reduced renal function, even within normal reference range. FUNDunding Acknowledgement Type of funding sources: None.

Abstract BACKGROUND Increased concentrations of remnant cholesterol are causally associated with increased risk of ischemic heart disease. We tested the hypothesis that increased remnant cholesterol is a risk factor for all-cause mortality in patients with ischemic heart disease. METHODS We included 5414 Danish patients diagnosed with ischemic heart disease. Patients on statins were not excluded. Calculated remnant cholesterol was nonfasting total cholesterol minus LDL and HDL cholesterol. During 35836 person-years of follow-up, 1319 patients died. RESULTS We examined both calculated and directly measured remnant cholesterol; importantly, however, measured remnant cholesterol made up only 9% of calculated remnant cholesterol at nonfasting triglyceride concentrations <1 mmol/L (89 mg/dL) and only 43% at triglycerides >5 mmol/L (443 mg/dL). Multivariable-adjusted hazard ratios for all-cause mortality compared with patients with calculated remnant cholesterol concentrations in the 0 to 60th percentiles were 1.2 (95% CI, 1.1–1.4) for patients in the 61st to 80th percentiles, 1.3 (1.1–1.5) for the 81st to 90th percentiles, 1.5 (1.1–1.8) for the 91st to 95th percentiles, and 1.6 (1.2–2.0) for patients in the 96th to 100th percentiles (trend, P < 0.001). Corresponding values for measured remnant cholesterol were 1.0 (0.8–1.1), 1.2 (1.0–1.4), 1.1 (0.9–1.5), and 1.3 (1.1–1.7) (trend, P = 0.006), and for measured LDL cholesterol 1.0 (0.9–1.1), 1.0 (0.8–1.2), 1.0 (0.8–1.3), and 1.1 (0.8–1.4) (trend, P = 0.88). Cumulative survival was reduced in patients with calculated remnant cholesterol ≥1 mmol/L (39 mg/dL) vs <1 mmol/L [log-rank, P = 9 × 10−6; hazard ratio 1.3 (1.2–1.5)], but not in patients with measured LDL cholesterol ≥3 mmol/L (116 mg/dL) vs <3 mmol/L [P = 0.76; hazard ratio 1.0 (0.9–1.1)]. CONCLUSIONS Increased concentrations of both calculated and measured remnant cholesterol were associated with increased all-cause mortality in patients with ischemic heart disease, which was not the case for increased concentrations of measured LDL cholesterol. This suggests that increased concentrations of remnant cholesterol explain part of the residual risk of all-cause mortality in patients with ischemic heart disease.

Abstract Background.—Cardiovascular disease remains the leading cause of mortality in the United States, accounting for approximately 33% of all deaths in this country. Of these deaths, most are due to acute myocardial infarctions (AMIs), which are associated with thrombotic coronary artery obstruction and/or occlusion. These events could potentially be due to alterations in genes coding for coagulation factors. Several polymorphisms have been described in the factor II, V, and VII genes, which may predispose one to increased risk for ischemic heart disease (IHD). Objective.—To determine if mutations in 3 coagulation factor genes could predispose an individual to increased risk for arterial thrombosis as a mechanism for developing unstable angina (UA) or AMI. Methods.—We examined 125 hospitalized patients (mean age, 53 ± 6 years, 79 men and 46 women), including 32 with AMI, 68 with UA, and 25 noncardiac controls, for a genetic predisposition for increased risk of IHD. EDTA-anticoagulated whole blood was collected at the time of hospital admission. DNA was extracted, and the polymorphisms were detected by polymerase chain reaction amplification of these genes with subsequent restriction enzyme digestion and gel electrophoresis. Results.—Our results showed that 3 (9.4%), 3 (4.4%), and 1 (4%) individuals were heterozygous for prothrombin G20210A and 3 (9.4%), 5 (7.4%), and 1 (4%) individuals were heterozygous for factor V Leiden in the AMI, UA, and control groups, respectively. The following genotype frequencies for the factor VII R353Q polymorphism were identified: 25 (78.1%), 56 (82.4%), and 18 (72%) with RR and 7 (21.9%), 12 (17.6%), and 7 (28%) with RQ in the AMI, UA, and control groups, respectively. No QQ homozygotes were identified. For the HVR4 size polymorphism, the following genotypes were identified: 3 (9.4%), 4 (5.9%), and 5 (20%) individuals with H7H7; 11 (34.4%), 33 (48.5%), and 12 (48%) with H6H7; and 18 (56.2%), 31 (45.6%), and 8 (32%) with H6H6 genotypes in the AMI, UA, and control groups, respectively. There were no H7H5 and H6H5 genotypes found in this study. Conclusions.—Although the frequency differences of these polymorphisms in patients with AMI and UA were not statistically significant from those in controls, several trends are consistent with what has been reported in the literature. Although any of these or other undefined genetic abnormalities may result in IHD, it is possible that phenotypic predisposition to IHD initially presents as UA. A larger population study addressing the significance of these polymorphisms in the sequence of events that lead to IHD, including cases of UA, is warranted.

Abstract Background In patients with stable ischemic heart disease (SIHD) the effect of revascularization on all-cause death (the most verifiable clinical event) is unknown. Objectives We explored the potential of the ischemic burden as derived from vasodilator stress cardiovascular magnetic resonance (CMR) to guide decision-making in this scenario. Methods In a large prospective multicenter registry, we recruited 6389 patients (mean age 65±11 years, 38% female) submitted to undergo vasodilator stress CMR for known or suspected SIHD. Baseline and CMR characteristics were prospectively recorded. The ischemic burden (at vasodilator stress first-pass perfusion imaging) and necrosis extent (at late enhancement imaging) were computed (17-segment model). The effect of CMR-related revascularization (within the following three months) on all-cause death (revised using the unified regional electronic health system registry) was explored. Results During a 5.75-year median follow-up, 717 (11.2%) all-cause deaths were documented. In multivariable analyses, more extensive ischemic burden (per 1-segment increase) independently related to all-cause death (1.05 [1.03–1.07], p<0.001). In 1034 patients (517 revascularized, 517 non-revascularized) strictly 1:1 matched for the independent predictors of outcome and of undergoing CMR-related revascularization (age, diabetes mellitus, male sex, LVEF, ischemic burden and necrosis extent), CMR-related revascularization did not significantly alter all-cause death rate (13.3% vs. 13.3%, p=0.54). Nevertheless, a potent interaction existed with the ischemic burden (p<0.001). CMR-related revascularization independently reduced the risk of all-cause death in 430 patients with ischemic burden >5 segments (9.3% vs. 16.3%, HR 0.56 [0.32–0.98], p=0.02) but it independently increased risk in 604 patients with ischemic burden ≤5 segments (16.2% vs. 11.3%, HR 1.59 [1.03–2.45], p=0.037). Figure 1. CMR-related revascularization Conclusions In patients with known or suspected stable ischemic heart disease the ischemic burden as derived from vasodilator stress CMR can be helpful to predict the effect of revascularization on long-term all-cause death.
