Gong X, Zhou R, Li Q. Effects of captopril and valsartan on ventricular remodeling and inflammatory cytokines after interventional therapy for AMI. Exp Ther Med 2018; 16:3579-3583. [PMID: 30233711 PMCID: PMC6143902 DOI: 10.3892/etm.2018.6626] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2018] [Accepted: 08/02/2018] [Indexed: 11/05/2022] Open
Abstract
The effects of captopril and valsartan on ventricular remodeling and inflammatory cytokines after interventional therapy for acute myocardial infarction (AMI) were investigated. A total of 94 patients with AMI admitted to Honggang Hospital of Dongying from July 2016 to June 2017 were selected as study subjects. The patients were treated with interventional therapy and randomly divided into the observation group (n=47) and the control group (n=47). The control group received aspirin after operation, while the observation group received captopril and valsartan after operation. Three-dimensional ultrasonography was performed to evaluate ventricular remodeling. The related parameters included left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), end-systolic sphericity index/end-diastolic sphericity index (ESSI/EDSI), systolic dyssynchrony index (SDI), diastolic dyssynchrony index (DDI), dispersion end systole (DISPES), DDI-late and DISPED-late. The levels of inflammatory cytokines were determined by enzyme-linked immunosorbent assay (ELISA). The incidence of adverse reactions after treatment was compared. After treatment, LVEF in the control group was significantly lower than that in the observation group, while LVEDV, LVESV and the ratio of early diastolic (E) and late diastolic (A) (E/A) in the control group were significantly higher than those in the observation group (p<0.05). EDSI, DDI-late and DISPED-late in the control group were significantly higher than those in the observation group (p<0.05). ESSI, SDI and DISPES in the control group were significantly higher than those in the observation group (p<0.05). The levels of interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α) in the observation group were significantly lower than those in the control group at 1, 4 and 8 weeks after treatment (p<0.05). The administration of captopril and valsartan after interventional therapy for AMI can effectively improve the cardiac function of patients, improve the synchronism of left ventricular diastole and contraction, and reduce the level of inflammation. It is safe and reliable, and has important clinical significance.

Abstract
Effects of tirofiban on stent thrombosis, high-sensitivity C-reactive protein (Hs-CRP), interleukin-6 (IL-6) and soluble intercellular adhesion molecule-1 (sICAM-1) after percutaneous coronary intervention (PCI) of acute myocardial infarction (AMI) were investigated. A total of 94 AMI patients receiving PCI in Shouguang City People's Hospital from January 2016 to September 2016 were selected and randomly divided into control (n=47) and observation group (n=47). The control group was treated with aspirin + clopidogrel before and after operation, while the observation group was treated with tirofiban based on the treatment of control group. The postoperative stent thrombosis was compared between the two groups, and the serum Hs-CRP, IL-6 and sICAM-1 levels before operation and at 24 and 48 h after operation were also compared between two groups. Moreover, the incidence rates of adverse reactions in the groups were observed. Finally, patients were followed-up for 1 year to observe the total incidence rate of adverse cardiac events and life quality of patients in both groups. The thrombolysis in myocardial infarction flow grading in observation after treatment was significantly superior to that in control group (P<0.05). The levels of Hs-CRP, IL-6 and sICAM-1 in both groups at 24 and 48 h after operation were significantly decreased compared with those before operation, and they were decreased more obviously in observation group (P<0.05); there were no significant differences in the incidence rates of adverse reactions between the groups (P>0.05). Besides, the 1-year follow-up showed that the total incidence rate of adverse cardiac events in observation was significantly lower than that in control group, and the life quality scores were obviously higher than those in control group (P<0.05). The treatment of AMI patients undergoing PCI with tirofiban can effectively prevent stent thrombosis, and alleviate the inflammatory response of patients, it is safe and reliable with important clinical significance.

Abstract
BACKGROUND Diabetes mellitus (DM) is an established adverse prognostic factor in patients sustaining myocardial infarction (MI). However, its impact on long-term survival remains less clear. The aim of this observational study was to quantify lifetime mortality and years of life lost after MI in patients with and without DM. METHODS In 1995, 2153 individuals with MI were recruited from 20 adjacent hospitals within Yorkshire, UK. Median survival, all-cause mortality at 20 years and lost years of life when compared to actuarial predictions were compared in patients with and without DM. Landmark analyses were conducted to define the ongoing impact of DM beyond specified time points. RESULTS 13% (279/2153) had known DM. They experienced higher mortality at 30 days (33.1% vs 24.6%; p<0.0001) and at 20 years (84.9% vs 75.7%; p<0.0001). Overall, there was a 48% increased risk of death (p<0.0001), which persisted after adjustment for potential confounders. There was no interaction between DM and prior MI in predicting mortality (p=0.67). Median survival decreased by 3.3 years (p<0.0001). The adverse impact of DM persisted in sequential landmark analyses at 1, 5 and 10 years. Presence of DM conferred 2 extra years of life lost when compared with actuarial predictions (8 vs 6 years; p<0.0001). CONCLUSIONS DM remains an independent adverse prognostic factor in the long-term after MI. Persistently diverging survival curves support enduring efforts to reduce mortality late after MI.

Abstract
Primary percutaneous coronary intervention (PPCI) is the recommended treatment for patients with acute ST-segment elevation myocardial infarction (STEMI). A survey conducted in 2008 in the European Society of Cardiology (ESC) countries reported that the annual incidence of hospital admissions for acute STEMI is around 800 patients per million inhabitants. The survey also showed that STEMI patients' access to reperfusion therapy and the use of PPCI or thrombolytic therapy (TT) vary considerably among countries. Northern, Western and Central Europe already had well-developed PPCI services, offering PPCI to 60-90% of all STEMI patients. Southern Europe and the Balkans were still predominantly using TT and had a higher proportion of patients who were left without any reperfusion treatment. The survey concluded that a nationwide PPCI strategy results in more patients being offered reperfusion therapy. To address the inequalities in STEMI patients' access to life-saving PPCI and to support the implementation of the ESC STEMI treatment guidelines in Europe, the Stent for Life (SFL) Initiative was launched jointly by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and EuroPCR in 2008. The aim of the SFL Initiative is to improve the delivery of life-saving PPCI for STEMI patients. Currently, 10 national cardiac societies support the SFL Initiative in their respective countries. SFL national action programmes have been developed and are being implemented in several countries. The formation of regional PPCI networks involving emergency medical services, non-PPCI hospitals and PPCI centres is considered to be a critical factor in implementing PPCI services effectively. Better monitoring of STEMI incidence and prospective registration of PPCI in all countries is required to document improvements in health care and to identify areas where further effort is required. Furthermore, studies on potential factors or characteristics that explain the national penetration of PPCI are needed. Such knowledge will be necessary to increase the effectiveness and efficiency of the implementation, and will be the first step in ensuring equal access to PPCI treatment for STEMI patients in Europe. Establishing the delivery of PPCI in an effective, high-quality and timely manner is a great challenge.

Abstract
BACKGROUND Studies before the turn of the century reported sex differences in procedure rates. It is unknown whether these differences persist. OBJECTIVES To examine time trends and sex differences in coronary catheterization and revascularization following acute myocardial infarction (AMI). METHODS A retrospective analysis was performed of all patients 20 years of age or older who were admitted to hospital in British Columbia with an AMI between April 1, 1994, and March 31, 2003. Segmented regression analysis was used to examine the inflection point of the time trend in 90-day catheterization rates post-AMI. Multivariable Cox regression modelling was used to evaluate sex differences in receiving catheterization and revascularization following AMI. RESULTS Ninety-day coronary catheterization rates increased significantly over the study period for both men and women (P<0.0001 for trend), with a steeper increase beginning in September 2000. Women were less likely to undergo catheterization than men, even after adjustment for baseline differences; this sex effect was modified by age and care in the intensive care unit or cardiac care unit (ICU⁄CCU). Specifically, ICU⁄CCU admission eliminated the sex difference among patients who were younger than 65 years of age. Conditional on receiving cardiac catheterization post-AMI, female sex was not associated with a lower likelihood of receiving revascularization within one year (HR 0.96; 95% CI 0.91 to 1.02). CONCLUSIONS Despite recent increases in catheterization rates post-AMI, women were less likely to undergo catheterization than men. Interestingly, access to ICU⁄CCU care removed the sex difference in catheterization access in patients younger than 65 years of age.

Abstract
AIMS Variations in the resources, stability and priorities of health care systems conceivably affect their capacity to implement health care reform and ensure an evidence based approach to health care. Such variation may partially account for differences in cardiovascular mortality rates between former communist states in Central Europe and Western European countries, but specific data on this subject is sparse. The aim of this study was to compare the presentation of stable angina to cardiology services in Poland vs. the United Kingdom, the management of the condition in relation to existing European guidelines and clinical outcome. METHODS AND RESULTS Data was collected as part of a prospective observational cohort study of stable angina in Europe. Information was recorded on referral patterns, clinical presentation and the use of pharmacological therapies, investigations, revascularisation and cardiovascular events during 1 year of follow up. A total of 571 patients with stable angina were enrolled in Poland and 319 in the UK. Patients presenting to cardiology services in Poland were less likely to be referred by a primary care physician, younger, and had more adverse clinical risk predictors at presentation. Non-invasive investigation and coronary angiography were performed less frequently in Poland, but waiting times for invasive assessment were shorter. European guidelines with regard to the use of evidence based secondary preventative medical therapy were applied widely by cardiologists in both countries. No differences were observed in rates of cardiovascular events. CONCLUSIONS The use of evidence based pharmacological therapy was equally high in both countries, but guidelines regarding investigation were less completely adhered to in Poland, where invasive assessment and subsequent management was prompt but only performed in a highly selected proportion of the population with stable angina.

Abstract
AIMS To examine the relationship between revascularization within 7 days and 1-year mortality among ST-elevation myocardial infarction patients enrolled in GUSTO-V trial (n=13 451). To examine the relative contribution of system and patient level factors to the variation in international revascularization rates, and their impact on mortality outcomes. METHODS AND RESULTS Patients from North America (USA, Canada), Australia, and Europe (UK, France, Germany, Italy, Spain, Poland, Norway, The Netherlands, Belgium, Finland) were included in the study. Revascularization was associated with lower 1-year mortality. Norway, Belgium, Spain, Poland, and Italy also had lower than expected revascularization rates but higher than expected mortality rates. France and USA had almost two times the expected rate of 7-day revascularization, which was associated with modest mortality benefits. Patients' propensity for revascularization based on clinical factors alone was associated with lower 1-year mortality (OR 0.97, 95% CI: 0.96-0.99). Country-level factors had an impact on propensity for revascularization but no impact on 1-year mortality. CONCLUSION Our study reveals the potential for some countries with lower than expected 7-day revascularization rates to improve their clinical outcomes. Also highlighted is the possibility for more economically efficient delivery of care in USA and France.

Abstract
In recent years, the characteristics of patients who suffer acute myocardial infarction without complications during hospitalization have changed. In addition, the range of non-invasive studies available for evaluating left ventricular systolic function, residual myocardial ischemia, and myocardial viability in these patients has improved. Left ventricular systolic function and residual ischemia should be evaluated in all patients before release. The non-invasive technique used (exercise test, echocardiography, nuclear cardiology, magnetic resonance imaging) depends on availability, experience, and results at each institution. Coronary arteriography should be performed in patients with significant ischemia or severe left ventricular systolic dysfunction in non-invasive studies. In these cases coronary angiography must be performed to determine if coronary arteries are suitable for revascularization before performing a test of myocardial viability.

Abstract
OBJECTIVE To estimate the need for coronary revascularisation, by using an incidence of indications approach, among 45-84 year olds with stable angina, unstable angina, and acute myocardial infarction. DESIGN Modelling exercise. Six key steps along the pathway of care from initial diagnosis in primary or secondary care to revascularisation were defined and the frequency of indications estimated using routine data from hospital admissions and data from studies in the general population, and primary and secondary care. SETTING AND PATIENTS Mid-1998 population of England. INTERVENTION Coronary revascularisation. MAIN OUTCOME MEASURE Ability to benefit (need), defined by randomised trials, expert panel ratings from the ACRE (appropriateness of coronary revascularisation) study, or by informal consensus. RESULTS The need for coronary revascularisation was estimated to be 92 000 procedures, equivalent to a rate of 1861 per million population. Overall, the model of need exceeded current provision by 3.3:1, although among people aged 75 years and over the ratio was 7.7:1. A plausible upper estimate of need--obtained by assuming that 90% of patients with stable angina were referred from primary care and that angiography would be performed in 65% of patients with acute myocardial infarction and 75% of patients with unstable angina--was 2626 per million population. CONCLUSIONS The national target of 1500 revascularisation procedures per million population is credibly related to population need, although upper estimates of need are considerably higher. Better understanding is required of the benefits of referring patients with specific indications from primary care. The greatest relative increase in provision is required for those aged 75 and older, among whom trial evidence of benefit is scant.

Abstract
BACKGROUND We evaluate the prognostic value of stress echo and gated single photon emission computed tomography (SPECT) after a first uncomplicated acute myocardial infarction. METHODS AND RESULTS We used predischarge maximal subjective exercise echocardiography and gated SPECT with technetium 99m tetrofosmin to prospectively study 103 patients younger than 70 years with a first acute myocardial infarction. During a 12-month follow-up period, 2 patients died, 9 had heart failure, and 29 had ischemic complications (4 reinfarction and 25 angina). Predictive variables for heart failure in multivariate analysis were ejection fraction evaluated by echocardiography (odds ratio [OR] 8.5, P =.016) or by gated SPECT (OR 10.7, P =.009). Predictive variables for ischemic complications in multivariate analysis were less than 5 metabolic equivalents (METS) in exercise test (OR 5.2, P =.007) and greater than 15% ischemic extent in the polar map (OR 3.6, P =.04) of SPECT. CONCLUSIONS Exercise echocardiography and Tc-99m tetrofosmin gated SPECT were predictive for heart failure, but exercise SPECT was the only test with predictive power for ischemic complications.

Abstract
BACKGROUND Previous studies have suggested that women with acute myocardial infarction (AMI) are less aggressively managed than are men. The aim of this study was to assess sex differences in medical and invasive coronary procedures (angiography, PTCA, and CABG) in AMI patients admitted to cardiac care units (CCUs) in Israel in the mid 1990s and their association with early and 1-year prognosis. METHODS AND RESULTS We studied 2867 consecutive AMI patients (2125 men, 74%) hospitalized in all 25 CCUs in Israel from 3 prospective nationwide surveys conducted in 1992, 1994, and 1996. Women were, on average, older than men (69 versus 61 years, P:<0.0001) and had a higher prevalence of hypertension, diabetes, Killip class >/=II on admission, and in-hospital complications. Women received aspirin and beta-blockers less often than did men, but these differences were not significant after age adjustment. The unadjusted rates of thrombolysis, angiography, and PTCA/CABG use were lower in women than in men but not after covariate adjustment: 42% versus 48% (adjusted odds ratio [OR] 0.92, 95% CI 0.77 to 1.11), 23% versus 31% (OR 0.88, 95% CI 0.70 to 1.09), and 15% versus 19% (OR 0.93, 95% CI 0.72 to 1.19), respectively. The 30-day mortality was higher in women than in men (17.6% versus 9.6%, respectively; OR 1.39, 95% CI 1.06 to 1.82), but the 30-day to 1-year mortality rate was not (9.1% versus 5.6%, respectively; hazard ratio 1.18, 95% CI 0.84 to 1.66). CONCLUSIONS This prospective nationwide observational community-based study of consecutive AMI patients hospitalized in the CCUs in the mid 1990s indicates that women fare significantly worse than do men at 30 days but not thereafter at 1-year. The difference in 30-day outcome was not influenced by the use of different therapeutic modalities, including thrombolysis and invasive coronary procedures, but was rather due to the older age and greater comorbidity of women; these findings seem also to explain the less frequent use of invasive procedures in women.

Abstract
BACKGROUND AND PURPOSE The paucity of data on myocardial infarction management and results in Spain lead to the design of the PRIAMHO study (Proyecto de Registro de Infarto Agudo de Miocardio Hospitalario [Acute Myocardial Infarction Hospital Registration Project]) which developed standard methods to collect information on the management of patients with such a condition and their characteristics. The variability results among hospitals in myocardial infarction management and in one-year mortality are presented. METHODS A cohort study with a one-year follow-up was designed to register all patients diagnosed with acute myocardial infarction discharged from 24 Spanish hospitals that completed all the requisites to participate. The demographic and clinical characteristics of the patients, their management during the coronary care unit stage, and the outcome and complications were prospectively registered. Standard definitions for diagnosis were used. Confidentiality regarding patient identity and participating centers was guaranteed. RESULTS 5,242 (77.6%) of the 6,756 patients with myocardial infarction admitted in the 24 participating hospitals were registered in the coronary care units. Half of the centers had an on-site hemodynamic laboratory and in seven coronary surgery. The delay between symptom-onset and emergency room admission was 2 hours. Acute pulmonary edema or cardiogenic shock was developed by 16.6% of patients and 41.8% received thrombolysis. Mean time delay between symptom-onset and thrombolysis was 3 hours. A large variability in the use of beta-blockers, thrombolysis, echocardiography, coronary catheterization angiography and invasive revascularization was observed among hospitals. Mortality in the coronary care unit was 10.9% and increased to 14.0% at 28 days and to 18.5% at one year with considerable variation among hospitals. Four hospitals showed higher mortality among their patients, independently from the proportion of diabetes, hypertension, women, anterior location of myocardial infarction, non-Q-wave infarction, age and severity. CONCLUSIONS The results of this study show that early and mid-term mortality from myocardial infarction is still high in Spain in the reperfusion era, and that a considerable variability in management and outcome exists among Spanish hospitals, which is not explained by the different case-mix among them.

Abstract
In the United States by mid-century, cardiovascular disease accounted for more than half of all deaths. In the second half of this century, 85% of reduction in age-adjusted mortality rates from all causes can be ascribed to the decline in death from cardiovascular disease and stroke. Approximately half of such dramatic decline in mortality rates from ischemic heart disease (IHD) can be explained by primary and secondary prevention and half by therapeutic improvements. Epidemiology of therapeutic regimens in acute myocardial infarction (AMI) indicates substantial increases in the use of thrombolytic therapy, aspirin, beta-blockers and, in some countries, coronary angioplasty. The long-term results of several thrombolytic trials have shown the persistence of early benefit until 10 years after AMI. However, approximately half of the patients with AMI are admitted to the hospital too late to fully benefit from thrombolytic therapy, and one fourth of eligible patients do not receive any form of reperfusion. Primary angioplasty is advocated by some as the treatment of choice in AMI. The present results are not convincing enough to induce the enormously complex and costly reorganization of the health system, allowing the immediate access to coronary angiography for all or most patients with AMI. However, stenting the infarct coronary artery at the site of previous occlusion appears to improve the immediate and medium-term results of coronary revascularization procedures. Approximately half of the AMI survivors are rehospitalized within 1 year after the index event, and postinfarction mortality rate remains exceedingly high. After AMI, prognostic and therapeutic procedures have been introduced in the absence of evidence from controlled trials of their effectiveness profile. Outcome research is needed to standardize effective post-AMI policies. Moreover, new strategies are needed to reduce the incidence and mortality rates of acute ischemic events. A number of new candidate risk factors for IHD are emerging; they are associated with endothelial dysfunction, thrombogenic state, and inflammatory state. It is hoped that advances in molecular approach to cardiovascular disease, molecular genetics and transgenic techniques will allow better understanding and more effective therapeutic strategies to prevent and control IHD.
