Text Messages to Improve Medication Adherence and Secondary Prevention After Acute Coronary Syndrome: The TEXTMEDS Randomized Clinical Trial.

BACKGROUND: TEXTMEDS (Text Messages to Improve Medication Adherence and Secondary Prevention After Acute Coronary Syndrome) examined the effects of text message-delivered cardiac education and support on medication adherence after an acute coronary syndrome. METHODS: TEXTMEDS was a single-blind, multicenter, randomized controlled trial of patients after acute coronary syndrome. The control group received usual care (secondary prevention as determined by the treating clinician); the intervention group also received multiple motivational and supportive weekly text messages on medications and healthy lifestyle with the opportunity for 2-way communication (text or telephone). The primary end point of self-reported medication adherence was the percentage of patients who were adherent, defined as >80% adherence to each of up to 5 indicated cardioprotective medications, at both 6 and 12 months. RESULTS: A total of 1424 patients (mean age, 58 years [SD, 11]; 79% male) were randomized from 18 Australian public teaching hospitals. There was no significant difference in the primary end point of self-reported medication adherence between the intervention and control groups (relative risk, 0.93 [95% CI, 0.84-1.03]; P=0.15). There was no difference between intervention and control groups at 12 months in adherence to individual medications (aspirin, 96% vs 96%; ß-blocker, 84% vs 84%; angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, 77% vs 80%; statin, 95% vs 95%; second antiplatelet, 84% vs 84% [all P>0.05]), systolic blood pressure (130 vs 129 mm Hg; P=0.26), low-density lipoprotein cholesterol (2.0 vs 1.9 mmol/L; P=0.34), smoking (P=0.59), or exercising regularly (71% vs 68%; P=0.52). There were small differences in lifestyle risk factors in favor of intervention on body mass index <25 kg/m2 (21% vs 18%; P=0.01), eating ≥5 servings per day of vegetables (9% vs 5%; P=0.03), and eating ≥2 servings per day of fruit (44% vs 39%; P=0.01). CONCLUSIONS: A text message-based program had no effect on medical adherence but small effects on lifestyle risk factors.

Early computed tomography coronary angiography and preventative treatment in patients with suspected acute coronary syndrome: A secondary analysis of the RAPID-CTCA trial.

BACKGROUND: Computed tomography coronary angiography (CTCA) offers detailed assessment of the presence of coronary atherosclerosis and helps guide patient management. We investigated influences of early CTCA on the subsequent use of preventative treatment in patients with suspected acute coronary syndrome. METHODS: In this secondary analysis of a multicenter randomized controlled trial of early CTCA in intermediate-risk patients with suspected acute coronary syndrome, prescription of aspirin, P2Y12 receptor antagonist, statin, renin-angiotensin system blocker, and beta-blocker therapies from randomization to discharge were compared within then between those randomized to early CTCA or to standard of care only. Effects of CTCA findings on adjustment of these therapies were further examined. RESULTS: In 1,743 patients (874 randomized to early CTCA and 869 to standard of care only), prescription of P2Y12 receptor antagonist, dual antiplatelet, and statin therapies increased more in the early CTCA group (between-group difference: 4.6% [95% confidence interval, 0.3-8.9], 4.5% [95% confidence interval, 0.2-8.7], and 4.3% [95% confidence interval, 0.2-8.5], respectively), whereas prescription of other preventative therapies increased by similar extent in both study groups. Among patients randomized to early CTCA, there were additional increments of preventative treatment in those with obstructive coronary artery disease and higher rates of reductions in antiplatelet and beta-blocker therapies in those with normal coronary arteries. CONCLUSIONS: Prescription patterns of preventative treatment varied during index hospitalization in patients with suspected acute coronary syndrome. Early CTCA facilitated targeted individualization of these therapies based on the extent of coronary artery disease.

Cognitive Function and the Relationship With Health Literacy and Secondary Prevention in Patients With Acute Coronary Syndrome at Early Discharge: A Prospective Observational Study.

BACKGROUND: Cognitive impairment (CI) may contribute to difficulties in understanding and implementing secondary prevention behavior change after acute coronary syndrome (ACS), but the association is poorly understood. OBJECTIVES: The aim of this study was to explore the prevalence of CI in patients 4 weeks post ACS and the association with health literacy and secondary prevention. METHODS: Patients with ACS who were free from visual deficits, auditory impairment, and dementia diagnoses were recruited and assessed 4 weeks post discharge for cognitive function (Montreal Cognitive Assessment and Hopkins Verbal Learning Test), health literacy (Newest Vital Sign), depression (Patient Health Questionnaire), physical activity (Fitbit Activity Tracker and Physical Activity Scale for the Elderly), and medication knowledge and adherence. RESULTS: Participants (n = 45) had an average age of 65 ± 11 years, 82% were male, 64% were married/partnered, and 82% had high school education or higher. Overall CI was identified in 28.9% (n = 13/45) of the patients 4 weeks after discharge, which was composed of patients detected on both the Montreal Cognitive Assessment and Hopkins Verbal Learning Test (n = 3), patients detected on Montreal Cognitive Assessment alone (n = 6), and patients detected on Hopkins Verbal Learning Test alone (n = 4). Fewer patients with CI had adequate health literacy (61.4%) than patients with normal cognition (90.3%, P = .024). Significant correlations were found between Hopkins Verbal Learning Test scores and medication knowledge (0.4, P = .008) and adherence (0.33, P = .029). CONCLUSIONS: In this exploratory study, 30% of patients with ACS demonstrated CI at 4 weeks post discharge. Two screening instruments were required to identify all cases. Cognitive impairment was significantly associated with health literacy and worth further investigation.

The association of mode of location activity and mobility with acute coronary syndrome: a nationwide ecological study.

BACKGROUND: We aimed to study the effect of social containment mandates on ACS presentation during COVID-19 pandemic using location activity and mobility data from mobile phone map services. METHODS: We conducted a cross-sectional study using data from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) including all ACS presentations during the pandemic until 7 May 2020. Using a count regression model, we adjusted for day of the week, daily weather and incidence of COVID-19. RESULTS: A 10% increase in activity around areas of residence was associated with 38% lower rates of ACS hospitalizations, whereas increased activity relating to retail and recreation, grocery stores and pharmacies, workplaces and mode of mobility was associated with 10-20% higher rates of ACS hospitalizations. CONCLUSION: Government policy regarding social containment mandates has important public health implications for medical emergencies such as ACS and may explain the decline in ACS presentations observed during COVID-19 pandemic.

Effect of once-weekly exenatide on hospitalization for acute coronary syndrome or coronary revascularization in patients with type 2 diabetes mellitus.

Cardiovascular (CV) outcome studies of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shifted the paradigm of type 2 diabetes management given their benefits regarding a reduction in major adverse CV events. However, the relationship between GLP-1 RAs and coronary revascularization remains poorly understood. In this EXSCEL post-hoc analysis, we used univariate Cox proportional models and Kaplan Meier survival analysis to evaluate the effect of once-weekly exenatide (EQW) on a composite outcome of hospitalization for acute coronary syndrome (ACS) or coronary revascularization. Similar models were utilized to evaluate the relationship between significant participant characteristics within the entire study population and the composite outcome. Of the 14,736 participants in EXSCEL with complete follow-up data, 1642 (11.1%) experienced an ACS or coronary revascularization event during a median follow-up of 3.3 years (interquartile range, 2.3-4.4). EQW had no effect on hospitalization for ACS or coronary revascularization (HR 1.00, 95% CI 0.91-1.10). Among EXSCEL participants, enrollment in Latin America (HR 0.51, 95% CI 0.43-0.60) and a history of peripheral artery disease (HR 0.79, 95% CI 0.70-0.90) were associated with a reduced risk for coronary revascularization, whereas enrollment in North America (HR 1.92, 95% CI 1.74-2.12), a history of CV disease (HR 3.24, 95% CI 2.78-3.78), and a previous myocardial infarction (HR 1.54, 95% CI 1.39-1.71) were associated with increased risk for study end points. EQW had no association with hospitalization for ACS or coronary revascularization. Participant enrollment location and CV disease burden may play a role in the variable CV efficacy of GLP-1 RAs that has been observed in trials thus far.

Impact of adherence to drugs for secondary prevention on mortality and cardiovascular morbidity: A population-based cohort study. IMPACT study.

PURPOSE: Adherence to pharmacological therapy for secondary prevention after an acute coronary syndrome (ACS) reduces the risk of new cardiovascular events. However, several studies showed poor adherence. Our study aim was to assess the risk of a composite endpoint of major cardiovascular events (MACE) and all-cause mortality according to the adherence to these drugs in patients after an ACS in a primary health care cohort. METHODS: Population-based observational cohort study of patients with a first episode of ACS during 2009-2016. DATA SOURCE: Information System for Research in Primary Care (SIDIAP) database. Drug adherence was evaluated through proportion of days covered (PDC). RESULTS: We included 7152 patients and 5692 (79.6%) were adherent (PDC ≥ 75%) to the study drugs during the first year after the event. Adherents to any combination showed a significant reduction of the composite endpoint risk (HR 0.80 [0.73-0.88]), and a significant lower probability of the composite endpoint than nonadherents for all drugs, except beta-blockers. Adherents to 2 (HR 1.2; 95% CI 1.0-1.3) and 1 drug (HR 1.5; 95% CI 1.2-1.8) had higher composite endpoint risk compared to adherents to 4-3 drugs. CONCLUSION: Adherence to any combination of recommended drugs reduced the composite endpoint risk, regardless the number of drugs prescribed. Adherence to a combination of 4-3 drugs was significantly associated with a reduced mortality risk compared with adherents to 2 or 1, but it was not significant for MACE.

Risk Categorization Using New American College of Cardiology/American Heart Association Guidelines for Cholesterol Management and Its Relation to Alirocumab Treatment Following Acute Coronary Syndromes.

BACKGROUND: The 2018 US cholesterol management guidelines recommend additional lipid-lowering therapies for secondary prevention in patients with low-density lipoprotein cholesterol ≥70 mg/dL or non-high-density lipoprotein cholesterol ≥100 mg/dL despite maximum tolerated statin therapy. Such patients are considered at very high risk (VHR) based on a history of >1 major atherosclerotic cardiovascular disease (ASCVD) event or a single ASCVD event and multiple high-risk conditions. We investigated the association of US guideline-defined risk categories with the occurrence of ischemic events after acute coronary syndrome and reduction of those events by alirocumab, a PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitor. METHODS: In the ODYSSEY OUTCOMES trial (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab), patients with recent acute coronary syndrome and residual dyslipidemia despite optimal statin therapy were randomly assigned to alirocumab or placebo. The primary trial outcome (major adverse cardiovascular events, ie, coronary heart disease death, nonfatal myocardial infarction, ischemic stroke, or hospitalization for unstable angina) was examined according to American College of Cardiology/American Heart Association risk category. RESULTS: Of 18 924 participants followed for a median of 2.8 years, 11 935 (63.1%) were classified as VHR: 4450 (37.3%) had multiple prior ASCVD events and 7485 (62.7%) had 1 major ASCVD event and multiple high-risk conditions. Major adverse cardiovascular events occurred in 14.4% of placebo-treated patients at VHR versus 5.6% of those not at VHR. In the VHR category, major adverse cardiovascular events occurred in 20.4% with multiple prior ASCVD events versus 10.7% with 1 ASCVD event and multiple high-risk conditions. Alirocumab was associated with consistent relative risk reductions in both risk categories (hazard ratio=0.84 for VHR; hazard ratio=0.86 for not VHR; Pinteraction=0.820) and by stratification within the VHR group (hazard ratio=0.86 for multiple prior ASCVD events; hazard ratio=0.82 for 1 major ASCVD event and multiple high-risk conditions; Pinteraction=0.672). The absolute risk reduction for major adverse cardiovascular events with alirocumab was numerically greater (but not statistically different) in the VHR group versus those not at VHR (2.1% versus 0.8%; Pinteraction=0.095) and among patients at VHR with multiple prior ASCVD events versus a single prior ASCVD event (2.4% versus 1.8%; Pinteraction=0.661). CONCLUSIONS: The US guideline criteria identify patients with recent acute coronary syndrome and dyslipidemia who are at VHR for recurrent ischemic events and who may derive a larger absolute benefit from treatment with alirocumab.

TicagRelor Or Clopidogrel in severe or terminal chronic kidney patients Undergoing PERcutaneous coronary intervention for acute coronary syndrome: The TROUPER trial.

Chronic kidney disease (CKD) is associated with an increased risk of acute coronary syndrome (ACS) and cardiovascular death. CKD patients suffering from ACS are exposed to an increased risk of thrombotic recurrences and a higher bleeding rate than patients with normal renal function. However, CKD patients are excluded or underrepresented in clinical trials. Therefore, determining the optimal antiplatelet strategy in this population is of utmost importance. We designed the TicagRelor Or Clopidogrel in severe or terminal chronic kidney patients Undergoing PERcutaneous coronary intervention for acute coronary syndrome (TROUPER) trial: a prospective, controlled, multicenter, randomized trial to investigate the optimal P2Y12 antagonist in CKD patients with ACS. Patients with stage ≥3b CKD are eligible if the diagnosis of ACS is made and invasive strategy scheduled. Patients are randomized 1:1 between a control group with a 600-mg loading dose of clopidogrel followed by a 75-mg/d maintenance dose for 1 year and an experimental group with a 180-mg loading dose of ticagrelor followed by a 90-mg twice daily maintenance dose for the same duration. The primary end point is defined by the rate of major adverse cardiovascular events, including death, myocardial infarction, urgent revascularization, and stroke at 1 year. Safety will be evaluated by the bleeding rate (Bleeding Academic Research Consortium). To demonstrate the superiority of ticagrelor on major adverse cardiovascular events, we calculated that 508 patients are required. The aim of the TROUPER trial is to compare the efficacy of ticagrelor and clopidogrel in stage >3b CKD patients presenting with ACS and scheduled for an invasive strategy. RCT# NCT03357874.

Targeting myocardial ischaemic injury in the absence of reperfusion.

Sudden myocardial ischaemia causes an acute coronary syndrome. In the case of ST-elevation myocardial infarction (STEMI), this is usually caused by the acute rupture of atherosclerotic plaque and obstruction of a coronary artery. Timely restoration of blood flow can reduce infarct size, but ischaemic regions of myocardium remain in up to two-thirds of patients due to microvascular obstruction (MVO). Experimentally, cardioprotective strategies can limit infarct size, but these are primarily intended to target reperfusion injury. Here, we address the question of whether it is possible to specifically prevent ischaemic injury, for example in models of chronic coronary artery occlusion. Two main types of intervention are identified: those that preserve ATP levels by reducing myocardial oxygen consumption, (e.g. hypothermia; cardiac unloading; a reduction in heart rate or contractility; or ischaemic preconditioning), and those that increase myocardial oxygen/blood supply (e.g. collateral vessel dilation). An important consideration in these studies is the method used to assess infarct size, which is not straightforward in the absence of reperfusion. After several hours, most of the ischaemic area is likely to become infarcted, unless it is supplied by pre-formed collateral vessels. Therefore, therapies that stimulate the formation of new collaterals can potentially limit injury during subsequent exposure to ischaemia. After a prolonged period of ischaemia, the heart undergoes a remodelling process. Interventions, such as those targeting inflammation, may prevent adverse remodelling. Finally, harnessing of the endogenous process of myocardial regeneration has the potential to restore cardiomyocytes lost during infarction.

Sodium-glucose cotransporter 2 inhibitor versus metformin as first-line therapy in patients with type 2 diabetes mellitus: a multi-institution database study.

BACKGROUND: Sodium-glucose co-transporter 2 inhibitors (SGLT2i) has shown evidence of cardiovascular benefit in patients with type 2 diabetes mellitus (T2DM). Currently metformin is the guideline-recommended first-line treatment. We aimed to investigate the benefit of SGLT2i vs metformin as first-line therapy. METHODS: Electronic medical records from Chang Gung Research Database during 2016-2019 were retrieved for patients with T2DM. Patients aged < 20, not receiving anti-diabetic medication, first-line treatment neither metformin nor SGLT2i were excluded. Primary outcomes were heart failure hospitalization, acute coronary syndrome, ischemic stroke, and all-cause mortality. Patients were followed up for events or December 31, 2019, whichever comes first. RESULTS: After exclusion criteria, a total of 41,020 patients with T2DM were eligible for analysis. There were 1100 patients with SGLT2i as first-line and 39,920 patients with metformin as first-line treatment. IPTW was used for propensity score matching. During one year follow-up, the hazard ratio (HR) of patients on SGLT2i as first-line treatment to patients on metformin as first-line treatment were HR 0.47 (95% CI 0.41-0.54, p < 0.0001) in heart failure hospitalization, HR 0.50 (95% CI 0.41-0.61, p < 0.0001) in acute coronary syndrome, HR 1.21 (95% CI 1.10-1.32, p < 0.0001) in ischemic stroke, and HR 0.49 (95% CI 0.44-0.55, p < 0.0001) in all-cause mortality. CONCLUSIONS: In patients with T2DM, SGLT2i as first-line treatment may be associated with decreased events of heart failure hospitalization, acute coronary syndrome, and all-cause mortality, compared with metformin as first-line treatment. However, there may be an increased events of ischemic stroke using SGLT2i compared to metformin.

Lipid-lowering therapy and low-density lipoprotein cholesterol goal attainment after acute coronary syndrome: a Danish population-based cohort study.

BACKGROUND: Patients with acute coronary syndrome (ACS) are at high risk of recurrent cardiovascular (CV) event. The European guidelines recommend low-density lipoprotein cholesterol (LDL-C) levels < 1.8 mmol/L and early initiation of intensive lipid-lowering therapy (LLT) to reduce CV risk. In order to reduce the risk of further cardiac events, the study aimed to evaluate LDL-C goal attainment and LLT intensity in an incident ACS population. METHODS: A cohort study of patients with residency at Funen in Denmark at a first-ever ACS event registered within the period 2010-2015. Information on LLT use and LDL-C levels was extracted from national population registers and a Laboratory database at Odense University Hospital. Treatments and lipid patterns were evaluated during index hospitalization, at 6-month and 12-month follow-up. RESULTS: Among 3040 patients with an LDL-C measurement during index hospitalization, 40.7 and 39.0% attained the recommended LDL-C target value (< 1.8 mmol/L) within 6- and 12-month follow-up, respectively. During 6- and 12-month follow-up, a total of 89.2% (20.2%) and 88.4% (29.7%) used LLT (intensive LLT). Of the intensive LLT users, 43.4 and 47.7% reached the LDL-C target value at 6- and 12-month follow-up. The frequency of lipid monitoring was low: 69.5, 77.7 and 53.6% in patients with a first-ever ACS during index hospitalization, 6- and 12-month follow-up, respectively. CONCLUSION: Using national health registers and laboratory data, a considerably gap was observed between treatment guidelines and clinical practice in the management of dyslipidemia leaving very high-risk patients without adequate lipid management strategy. Therefore, improved lipid management strategies aimed at reaching treatment targets are warranted.

Concomitant use of direct oral anticoagulants and aspirin versus direct oral anticoagulants alone in atrial fibrillation and flutter: a retrospective cohort.

BACKGROUND: The benefit of combining aspirin and direct oral anticoagulants on the reduction of cardiovascular events in atrial fibrillation or flutter is not well studied. We aimed to assess whether concurrent aspirin and direct oral anticoagulant therapy for atrial fibrillation or flutter will result in less coronary, cerebrovascular and systemic ischemic events compared to direct oral anticoagulant therapy alone. METHODS: Retrospective study of adult patients between 18 and 100 years old who have nonvalvular atrial fibrillation or flutter and were started on a direct oral anticoagulant (apixaban, rivaroxaban, or dabigatran), between January 1, 2010 and September 1, 2015 within the Beaumont Health System. Exclusions were history of venous thromboembolic disease and use of other antiplatelet therapies such as P2Y12 inhibitors. Patients were classified into two groups based on concurrent aspirin use and observed for a minimum of 2 years. Primary outcome was major adverse cardiac events, defined as acute coronary syndromes, ischemic strokes, and embolic events. Secondary outcomes were bleeding and death. RESULTS: Six thousand four patients were in the final analysis, 57% males and 80% Caucasians, median age 71, interquartile range (63-80). The group exposed to aspirin contained 2908 subjects, and the group unexposed to aspirin contained 3096 subjects. After using propensity scores to balance the baseline characteristics in both groups, the analysis revealed higher rate of major adverse cardiac events in the exposed group compared to the unexposed group, (HR 2.11, 95% CI (1.74-2.56)) with a number needed to harm of 11 (95% CI [9-11]). The rate of bleeding was also higher in the exposed group, (HR 1.30, 95% CI (1.11-1.52)). The rate of death was not statistically different between the groups, (HR 0.87, 95% CI (0.61-1.25)). CONCLUSIONS: In this observational analysis of patients with atrial fibrillation and flutter, the concomitant use of direct oral anticoagulants and aspirin was associated with an increased risk of both major adverse cardiac and bleeding events when compared to the use of direct oral anticoagulants alone. These findings underscore the potential harm of this combination therapy when used without a clear indication.

Underuse of beta-blockers by patients with COPD and co-morbid acute coronary syndrome: A nationwide follow-up study in New Zealand.

BACKGROUND AND OBJECTIVE: Clinical guidelines recommend the use of beta-blockers and other cardiovascular prevention drugs in patients with acute coronary syndrome (ACS). Studies in several countries have found that beta-blockers are underused in patients with chronic obstructive pulmonary disease (COPD) and co-morbid heart disease, although most have only examined use in subgroups of patients. We undertook a nationwide follow-up study in New Zealand to describe the use of beta-blockers and other cardiovascular prevention drugs in patients with COPD and ACS. METHODS: National health and pharmaceutical dispensing data were used to derive the study cohort, identify patients who were admitted to hospital with ACS and/or heart failure before cohort entry and during follow-up, and ascertain drug use. RESULTS: The study cohort included 83 435 patients aged ≥45 years, with 290 400 person-years of follow-up. Among 2637 patients with ≥1 ACS admission during follow-up, only 56.6% received a beta-blocker in the 6 months following the first admission, while 87.7% and 81%, respectively, received aspirin and a statin. Patients with higher COPD severity were less likely to receive a beta-blocker than those with lower severity, as were those with no history of previous ACS and/or heart failure. CONCLUSION: Use of beta-blockers following an ACS admission was much lower than expected based on the findings of general audits of ACS management in New Zealand. Along with the higher proportions using aspirin and statins, and the differences in beta-blocker dispensing by COPD severity, this suggests a particular reluctance to prescribe beta-blockers to patients with COPD.

Target Doses of Secondary Prevention Medications Are Not Being Achieved in Patients With Reduced Left Ventricular Ejection Fraction After Acute Coronary Syndrome (ANZACS-QI 34).

BACKGROUND: Patients with reduced left ventricular ejection fraction (EF<40%) are at high risk for adverse outcomes and benefit from evidence based doses of angiotensin converting enzyme inhibitors (ACEi), angiotensin II receptor blockers (ARB) and beta blockers. Our aim was to investigate the dispensing and uptitration of these medications following acute coronary syndrome (ACS), according to left ventricular ejection fraction. METHODS: Patients presenting with ACS who underwent coronary angiography during 2015 were recorded in the All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) registry. Medication dispensing data on discharge and at 1-year follow-up were obtained using anonymised linkage to the national pharmaceutical dataset. Doses of medications dispensed were compared to target doses recommended in clinical guidelines. RESULTS: 4,082 patients were included in the study, of whom 602 (15%) had reduced ejection fraction (rEF). More patients with rEF were prescribed ACEi/ARB on discharge compared to those with preserved ejection fraction (pEF) (89% vs. 68%). Beta blocker dispensing on discharge was also higher in the rEF group (94% vs. 83%). In the rEF subgroup, 76% were maintained on ACEi/ARB and 85% on beta blockers by 1 year of follow-up. However, at discharge only 31% and 29% were on ≥50% of target doses of ACEi/ARB and beta blocker doses respectively, and by 1 year this increased only slightly to 34% and 35% respectively. CONCLUSIONS: There is suboptimal dispensing of evidence-based medications in the year following ACS. Further intervention is required to improve medication uptitration and adherence, particularly of beta blockers and ACEI/ARBs in those with reduced ejection fraction.

Secondary prevention after acute coronary syndrome.

Patients suffering acute coronary syndrome have a very high risk for a repeated syndrome. After stabilization of acute coronary syndrome and discharge of a patient it is important to educate the patient how to prevent it in the future (dietary and life style changes), but treatment of all cardiovascular risk factors/diseases, as hypertension, dyslipidemia, diabetes but stabilization of all cardiovascular diseases is also important. Important is also antithrombotic treatment (mostly double antiplatelet treatment when percutaneous coronary intervention was used with a coronary stents), RAAS blockers, betablockers and statins (strong as atorvastatin and rosuvastatin in the highest possible dose). There are also new risk factors, and vascular inflammation belongs here. We have nowadays also some successful clinical studies how to block inflammation and how to use this treatment. A good secondary cardiovascular prevention is able to improve enourmously prognosis of these patients.

Administration of losartan improves aortic arterial stiffness and reduces the occurrence of acute coronary syndrome in aged patients with essential hypertension.

BACKGROUNDS AND AIMS: Increased arterial stiffness may increase cardiovascular morbidity and mortality. Angiotensin II type 1 receptor blocker losartan is potentially useful in controlling the central blood pressure and arterial stiffness in mild to moderate essential hypertension, while the effects of losartan in aged patients with essential hypertension are not entirely investigated. METHODS: The carotid-femoral arterial pulse wave velocity (PWV) was measured in aged patients with essential hypertension. RESULTS: In a cross-sectional study, PWV value was significantly higher in these old patients with essential hypertension, compared with patients without essential hypertension. Logistic regression analysis indicated that age, hypertension duration, and losartan treatment are risk factors of arterial stiffness. In a perspective study, long-term administration of losartan (50 mg/d) remarkably reduced PWV in aged patients with essential hypertension. In a longitudinal study, PWV is an independent predictor of the occurrence of acute coronary syndrome (ACS) in elderly patients with essential hypertension by using multivariate analysis. Further, the ACS occurrence was reduced by long-term administration of losartan in aged patients with essential hypertension, compared with the old hypertensive patients without taking losartan. CONCLUSION: Losartan treatment is a negative risk factor of arterial stiffness and reduces the risk of ACS in aged patients with essential hypertension.

Prognostic significance, angiographic characteristics and impact of antithrombotic and anticoagulant therapy on outcomes in high versus low grade coronary artery ectasia: A long-term follow-up study.

OBJECTIVES: To assess the prognostic significance of high vs. low grade coronary artery ectasia (CAE) and the impact of antithrombotic or anticoagulant therapy on adverse cardiac outcomes. BACKGROUND: There is paucity of knowledge on the impact of angiographic characteristics in CAE or that of antithrombotic or anticoagulant therapy on outcomes. METHODS AND RESULTS: In this retrospective study, we reviewed angiograms and medical records of all cases of confirmed CAE (2001-2011). Extent of CAE was categorized using the Markis classification. Types 1 and 2 were categorized as high-grade and types 3 and 4 as low-grade CAE. Angiographic flow was recorded as normal or sluggish (

Intensive lipid-lowering therapy in the 12 months after an acute coronary syndrome in Australia: an observational analysis.

OBJECTIVE: To determine the prevalence and identify predictors of people hospitalised with acute coronary syndrome (ACS) receiving intensive lipid-lowering therapy during the 12 months after their discharge from hospital. DESIGN: Retrospective observational analysis. SETTING: Data were extracted from CONCORDANCE, a prospective, Australian investigator-initiated ACS registry. PARTICIPANTS: Patients enrolled in CONCORDANCE during January 2015 - May 2016 who survived to hospital discharge, for whom information on lipid-lowering therapy 6 or 12 months after discharge from hospital were available. MAIN OUTCOME MEASURES: Not receiving intensive lipid-lowering therapy (with or without ezetimibe) at the most recent follow-up (6 or 12 months); predictors of not receiving intensive lipid-lowering therapy. RESULTS: 1876 of 3441 patients (55%) were receiving intensive lipid-lowering therapy 6 or 12 months after their hospitalisation with an ACS. Predictors of not receiving intensive lipid-lowering therapy included not been prescribed this treatment prior to their hospital admission (odds ratio [OR], 1.53; 95% CI, 1.26-1.85) or at hospital discharge (aOR, 7.24; 95% CI, 4.37-12.0), being a woman (aOR, 1.20; 95% CI, 1.02-1.41), and not being referred for cardiac rehabilitation (aOR 1.39; 95% CI, 1.09-1.78). Patients who were managed medically in hospital (not revascularised; aOR, 1.54; 95% CI, 1.25-1.91) or underwent coronary artery bypass grafting (aOR 1.55; 95% CI, 1.26-1.92) were less likely to be receiving intensive lipid-lowering therapy at follow-up than those with a percutaneous coronary intervention. Unmeasured hospital factors accounted for 17% of the variation in the likelihood of intensive lipid-lowering therapy. CONCLUSIONS: 45% of patients in Australia are not receiving intensive lipid-lowering therapy in the 12 months after their ACS. Optimising oral lipid-lowering therapy would reduce the recurrence of coronary events in this high risk group.

[Acute coronary syndrome : Prevention]. / Akutes Koronarsyndrom : Prävention.

For life style modifications primary and secondary prevention of acute coronary syndrome (ACS) are approximately similar, even though in the postinfarction situation functional diagnostic programs have to be performed in a rehabilitative manner. All three life style pillars of fitness, nutrition and relaxation implicate prognostic significance and the efficacy is higher for secondary prevention than for primary. The pharmacotherapeutic indications for thrombocyte aggregation inhibition are connected to the presence of atherosclerosis and statin medication is already connected to cardiovascular risk factor stratification, for which scores are used. Depending on the postinfarction myocardial destruction after ACS, additional pharmacotherapies, such as angiotensin-converting enzyme (ACE) inhibitors, angiotensin-II receptor antagonists, beta blockers and also mineral corticoid receptor antagonists are evident. New potential for prevention is ascribed to the new oral anticoagulants (NOAC) in the context of coincidental atrial fibrillation.

TIMI risk score for secondary prevention of recurrent cardiovascular events in a real-world cohort of post-non-ST-elevation myocardial infarction patients.

BACKGROUND: Patients who survive non-ST-elevation myocardial infarction (NSTEMI) are at heightened risk of recurrent cardiovascular events. Data on long-term secondary atherothrombotic risk stratification are limited. OBJECTIVES: To stratify post-NSTEMI patients for risk of recurrent cardiovascular events to maximise benefit from aggressive secondary prevention strategies using the TIMI Risk Score for Secondary Prevention (TRS 2°P) score in a real-world cohort of NSTEMI patients. METHODS AND RESULTS: This was a single-centre observational study of 891 post-NSTEMI patients (73.7 ± 12.7 years; male: 54.2%). The TRS 2°P is a nine-point risk stratification tool to predict cardiovascular events in patients with established cardiovascular disease. The primary outcome was a composite endpoint of cardiovascular death, non-fatal MI and non-fatal ischaemic stroke. After a median follow-up of 31 months (IQR: 11.4 - 60.2), 281 patients (31.5%) had developed a primary outcome (13.3%/year) including 196 cardiovascular deaths, 94 non-fatal MIs and 22 non-fatal strokes. The TRS 2°P score was strongly associated with the primary outcome. The annual incidence of primary composite endpoint for patients with TRS 2°P score =0 was 1.6%, and increased progressively to 47.4% for those with a TRS 2°P score ≥6 (HR: 20.18, 95% CI: 4.85 to 84.05, p<0.001). Similar associations were also observed between the TRS 2°P score and cardiovascular death and MI (fatal and non-fatal), but not non-fatal ischaemic stroke. CONCLUSION: The TRS 2°P score stratified post-NSTEMI patients for risk of future cardiovascular events and potentially help guide the selection of more aggressive secondary prevention therapy.
