Background : Lipid lowering therapy reduces mortality in patients with both ischemic and nonischemic cardiomyopathies and recently has been shown to decrease ICD shocks. Radiofrequency ablation (RFA) of recurrent VT in patients with an ICD also reduces shocks following intervention. It is unclear if statin therapy after VT RFA will further impact ICD shock rates. Methods : All patients from 1993–2005 who underwent a RFA procedure for recurrent VT at the Mayo Clinic with an ICD were included. Patient records were extracted for medical and procedural details and all ICD interrogations were reviewed for VT recurrence and therapies. Results: 63 patients (age 62±15 years) were followed over 3.9±3.6 years. Comorbid diseases included: coronary artery disease 37(58%, 34 prior myocardial infarction), ARVD/C 6(10%), nonischemic dilated cardiomyopathy 7(11%), moderate-severe valve disease 14(22%), hypertension 34(54%), and hyperlipidemia 35(56%). Ejection fraction was <0.35 in 34(56%). VT was induced in all patients (LV 55 (LVOT 1), RV 8 (RVOT 3) with multiple inducible VTs in 21(33%). VT was noninducible after RFA in 39(62%) patients. Dismissal medications included: statins 19(30%), beta blockers 40(66%), ACE/ARB 37(61%), diuretics 34(55%), and digoxin 23(37%). 5-year overall survival was 63%(95% CI 55–71). Age, diabetes, and renal insufficiency were associated with increased post ablation mortality, with no medication improving survival. 5-year survival free of ICD shocks was 31%(95% CI 24–38). Only statin therapy at discharge was associated with a decreased risk of ICD shocks [5(26%) versus 26(59%), p=0.020]. 7 additional patients received statins during follow-up, but not at discharge, of these 5(71%) had shocks. Conclusion : Statin use at discharge in patients with an ICD undergoing RFA for refractory VT significantly reduced recurrent ventricular arrhythmias and ICD shocks. Although the mechanism underlying the effects of statins on arrhythmic recurrence early after RFA requires further study, these data support aggressive therapy of the underlying substrate responsible for the VT.

Background: Patients undergoing percutaneous coronary intervention (PCI) represent a high-risk cohort for cardiovascular events. Lipid lowering therapy is an established core measure of secondary prevention in coronary artery disease management. The NCEP-ATPIII advises a minimum LDL level < 100 mg/dL in patients with coronary heart disease (CHD). However, further research suggests that an LDL < 70 is more desirable in this population to further reduce adverse CHD endpoints. Methods: We conducted a retrospective, observational study on all patients undergoing PCI at an urban Veterans Hospital from September 2004 to December 2011. Statin use and lipid profiles at 6 months post-PCI were compared to pre-PCI values. Results: A total of 1052 unique patients had PCI during the study period. Approximately 70% of patients were on statins at baseline, which improved to 88% at 6 months post-PCI (p < 0.0001). LDL levels improved significantly when compared to pre-PCI levels, from a mean of 97.2 to 85.1 (p < 0.0001). With regards to NCEP-ATPIII guidelines, the proportion of the study population that met minimum LDL goals (<100) post-PCI increased from 59% to 76% (p < 0.0001). The percentage of patients meeting ideal goals for LDL (<70) increased from 23% to 33% (p < 0.0001). Conclusion: In patients who have undergone PCI, there was significant improvement in LDL levels. At six months, there was an increase in usage of statin therapy. Furthermore there was a statistically significant increase in adherence to NCEP-ATIII guidelines at both the minimum and ideal LDL levels on follow-up after PCI.

Aim. To study the prescription rate of lipid-lowering therapy and achieving the target low-density lipoprotein cholesterol (LDL-C) values in outpatients with coronary artery disease (CAD) living in Krasnoyarsk.Material and methods. The study included all patients with CAD hospitalized in the cardiology department of the clinic of the Research Institute of Medical Problems of the North (Krasnoyarsk) in 2018-2019. The analysis included data from 1671 patients (men, 770; women, 901). During hospitalization, an in-depth survey of patients was carried out on the subject of prescribing and taking lipid-lowering drugs. On admission, lipid profile was assessed in all patients.Results. At the time of admission, only 51,4% of patients received lipidlowering therapy. The majority received statin monotherapy (99,2%). Only 0,8% of patients received combination therapy (statin+ezetimibe). The most frequently prescribed statin in the study was atorvastatin — 74,6%. Rosuvastatin was received by 17,1% of patients. In most cases, the doses of atorvastatin and rosuvastatin corresponded to the moderate-intensity statin therapy regimen. The frequently prescribed dose of atorvastatin was 20 mg/day — 54,4%, rosuvastatin — 10 mg/day — 68,7%. The target level of LDL-C <1,8 mmol/L was reached by 16,3%, <1,5 mmol/L — by 9,0%, <1,4 mmol/L — only 6,5% of patients. Most often, the target LDL-C levels were achieved by patients receiving high-intensity statin (HIS) therapy. The target level of LDL-C <1,8 mmol/L was reached by 37,5%, <1,5 mmol/L — 23,9%, LDL cholesterol <1,4 mmol/L — 20,7% of patients, receiving HIS.Conclusion. In patients with CAD living in Krasnoyarsk, the most commonly prescribed statins were atorvastatin and rosuvastatin, but only 32% of patients received HIS. Combination lipid-lowering therapy has been used extremely rarely. Among the surveyed patients, the current target level of LDL-C for patients with CAD (<1,4 mmol/L) was achieved only in 6,5% of patients. In the group of patients receiving high-intensity statin therapy, this target level was achieved in 20,7% of patients, which indicates the need for strict adherence to current clinical guidelines.

AbstractThe degree to which polygenic risk scores (PRS) influence preventive health is the subject of debate, with few prospective studies completed to date. We developed a smartphone application for the prospective and automated generation, communication, and electronic capture of response to a PRS for coronary artery disease (CAD). We evaluated self-reported actions taken in response to personal CAD PRS information, with special interest in the initiation of lipid lowering therapy (NCT03277365). 20% of high genetic risk (n=95) vs 7.9% of low genetic risk individuals (n=101) initiated lipid lowering therapy at follow-up (p-value = 0.002). The initiation of both statin and non-statin lipid lowering therapy was associated with degree of genetic risk – 15.2% (n=92) vs 6.0% (n=100) for statins (p-value = 0.018) and 6.8% (n=118) vs 1.6% (n=123) for non-statins (p-value = 0.022) in high vs low genetic risk, respectively. Overall, degree of genetic risk was associated with use of any lipid lowering therapy at follow-up - 42.4% (n=132) vs 28.5% (n=130) (p-value = 0.009). We also find that CAD PRS information is perceived to be understandable, actionable, and does not induce health anxiety.

Introduction: The clinical benefit from LDL-C lowering therapy in the elderly remains debated. Aim: To synthesize the efficacy of lowering LDL-C in patients aged ≥75 years in the light of most recently published data. Methods: Medline database was searched for the most recent evidence (2015-2020). The key inclusion criterion was a randomized controlled cardiovascular outcome trial testing an LDL-C lowering therapy with data available in patients aged ≥75 years at randomization. For efficacy, we meta-analyzed the risk ratio (RR) of major vascular events (a composite of cardiovascular (CV) death, myocardial infarction, stroke or coronary revascularization) per 1-mmol/L reduction in LDL-C. Results: Among 244,090 patients from 29 trials, 21,492 (8.8%) were elderly; 11,750 from statin trials, 6209 from ezetimibe trials, and 3533 from PCSK9 inhibitor trials. Median follow-up ranged from 2.2-6.0 years. LDL-C lowering therapy significantly reduced major vascular events (n=3519) in the elderly by 26% per 1-mmol/L LDL-C reduction (RR 0.74 [0.61-0.89], P=0.002), which was at least as good as the magnitude of effect seen in the non-elderly patients (RR 0.85 [0.78-0.92]; P interaction =0.24). Amongst the elderly, the RR was similar for statin (0.81 [0.70-0.94]) and non-statin therapy (0.67 [0.47-0.95]; P interaction =0.60). The benefit of LDL-C lowering in the elderly was observed for each component of the composite, including CV death (RR 0.85 [0.73-0.996], P=0.045), myocardial infraction (RR 0.80 [0.70-0.92], P=0.001), stroke (RR 0.71 [0.58-0.87], P=0.001) and coronary revascularization (RR 0.78 [0.63-0.96], P=0.017). Conclusion: In patients 75 years and older, lipid-lowering therapy is as effective in reducing CV events as it is in younger adults. These results should strengthen guideline recommendations for the use of lipid-lowering therapies, including non-statin therapy, in the elderly.

Introduction: Heterozygous familial hypercholesterolemia (heFH) is characterized by high levels of low-density lipoprotein cholesterol (LDL-C) and increased risk for premature coronary artery disease (CAD) and death. Reduction of CAD and mortality by statins has not been properly quantified in heFH. The aim of the current study is to determine the effect of statins on CAD and mortality in heFH. Methods: All adult heFH patients identified by the Dutch FH screening program between 1994 and 2014 and registered in the PHARMO Database Network were eligible. Of these patients we obtained hospital, pharmacy (in- and outpatient), and mortality records in the period between 1995 and 2015. The effect of statins (time-varying) on CAD and all-cause mortality was determined using a Cox proportional hazard model, while correcting for the use of other lipid-lowering therapy, thrombocyte aggregation inhibitors, antihypertensive and antidiabetic medication (all time-varying). Furthermore, we used inverse probability for treatment weighting (IPTW) to account for differences between statin-treated and untreated patients regarding history of CAD before follow-up, age at start of follow-up and age of screening, as well as body mass index, LDL-C and triglycerides. Results: Of the 25,479 identified heFH patients, 11,021 gave informed consent to obtain their medical records, of whom 2,447 could be retrieved. We excluded 766 patients younger than 18. The remaining 1,681 heFH patients comprised our study population and these had very similar characteristics as compared to the 23,798 excluded FH patients, e.g. mean (SD) LDL-C levels were 214 (74) vs. 203 (77) mg/dL. Among 1,151 statin users, there were 133 CAD events and 15 deaths during 10,115 statin treated person-years, compared to 17 CAD events and 9 deaths during 4,965 person-years in 530 never statin users (combined rate: 14.6 vs. 5.2, respectively, p<0.001). After applying IPTW to account for indication bias and correcting for use of other medications, the hazard ratio of statin use for CAD and all-cause mortality was 0.61 (0.40 - 0.93). Conclusions: In heFH patients, statins lower the risk for CAD and mortality by 39%.

Abstract Introduction The International Atherosclerosis Society (IAS) has proposed “severe familial hypercholesterolemia (FH)” as a FH phenotype with the highest cardiovascular risk. Coronary artery disease (CAD) represents a major atherosclerotic change in FH patients. Given their higher LDL-C level and atherogenic clinical features, more extensive formation of atherosclerosis cardiovascular disease including not only CAD but stroke/peripheral artery disease (PAD) may more frequently occur in severe FH. Methods 481 clinically-diagnosed heterozygous FH subjects were analyzed. Severe FH was defined as untreated LDL-C>10.3 mmol/l, LDL-C>8.0 mmol/l+ 1 high-risk feature, LDL-C>4.9 mmol/l + 2 high-risk features or presence of clinical ASCVD according to IAS proposed statement. Cardiac (cardiac death and ACS) and non-cardiac (stroke and peripheral artery disease) events were compared in severe and non-severe FH subjects. Results Severe FH was identified in 50.1% of study subjects. They exhibit increased levels of LDL-C and Lipoprotein (a) with a higher frequency of LDLR mutation. Furthermore, a proportion of %LDL-C reduction>50% was greater in severe FH under more lipid-lowering therapy (Table). However, during the observational period (median=6.3 years), severe FH was associated with a 5.9-fold (95% CI, 2.05–25.2; p=0.004) and 5.8-fold (95% CI, 2.02–24.7; p=0.004) greater likelihood of experiencing cardiac-death/ACS and stroke/PAD, respectively (picture). Multivariate analysis demonstrated severe FH as an independent predictor of both cardiac-death/ACS (hazard ratio=3.39, 95% CI=1.12–14.7, p=0.02) and stroke/PAD (hazard ratio=3.38, 95% CI=1.16–14.3, p=0.02) events. Clinical characteristics of severe FH Non-severe FH Severe FH P-value Baseline LDL-C (mmol/l) 5.3±1.5 6.6±2.0 <0.0001 Lp(a) (mg/dl) 15 [8–28] 21 [10–49] <0.0001 LDLR mutation (%) 49.6% 58.9% 0.00398 On-treatment LDL-C (mmol) 133 [106–165] 135 [103–169] 0.9856 %LDL-C reduction>50% 21.3% 49.8% <0.0001 High-intensity statin (%) 13.3% 42.3% <0.0001 PCSK9 inhibitor (%) 6.3% 21.2% <0.0001 Clinical outcome Conclusions Severe FH subjects exhibit substantial atherosclerotic risks for coronary, carotid and peripheral arteries despite lipid lowering therapy. Our finding underscore the screening of systemic arteries and the adoption of further stringent lipid management in severe FH patients.
