Abstract Introduction. Cardiovascular events represent an important cause of morbidity and mortality in the entire population. Arterial stiffness is currently considered one of the most important risk factors for the development of cardiovascular events. The gold-standard for evaluating arterial stiffness is pulse wave velocity (PWV). Recent studies have demonstrated that PWV is an independent risk factor regarding the development of cardiovascular events, especially in certain categories of patients. Material and Methods. The development of cardiovascular events was assessed in 174 patients admitted in the Center of Internal Medicine, Fundeni Clinical Institute, between January 2011 – May 2012. Arterial stiffness was evaluated by measuring PWV using the Sphygmocor system (AtCor, Australia), which is based on the principle of applanation tonometry. The patients were monitored for the development of cardiovascular events (ischemic heart disease, heart failure, stroke, acute myocardial infarction) and for death of cardiovascular cause, over a median period of 51.5 months (43-60 months). Results. Of the 174 patients, 81 (46.6%) were women and 93 (53.4%) were men. Mean age was 55.96 years. 93 of the 174 patients had chronic kidney failure in different stages (47.3% in stage V). Regarding PWV in the patient group, we obtained a mean score of 9.382. We observed a significant difference regarding the PWV level only for acute myocardial infarction and death between patients who developed these events and those who did not. Conclusions. Our study demonstrates that PWV increase can be positively associated with the occurrence of cardiovascular events, particularly in certain groups of patients

Background increased arterial stiffness is a predictor of cardiovascular events. The stroke volume (SV) to pulse pressure (PP) ratio is an estimate of arterial capacitance. Pulse wave velocity (PWV) is a measure of arterial stiffness. This study evaluated the effect of left ventricular (LV) SV on the SV/PP–PWV relationship. Methods 97 patients had applanation tonometry and echocardiography to measure arterial capacitance (SV/PP), PWV, and central aortic pressure. Results 50 patients had normal SV and 47 had low SV. For all patients, PWV inversely correlated with SV/PP. PWV and SV/PP correlated more strongly in the normal SV group than in the low SV group. Aortic PP was significantly correlated with PWV in all patients, in the normal SV group, and in the low SV group. Conclusion effective arterial capacitance correlates with PWV. The presence of decreased SV weakens the relationship.

Abstract Background The CHADS2score has mainly been used to predict the likelihood of cerebrovascular accidents in patients with atrial fibrillation. However, increasing attention is being paid to this scoring system for risk stratification of patients with coronary artery disease. We investigated the value of the CHADS2 score in predicting cardiovascular events in Japanese acute myocardial infarction (AMI) patients without atrial fibrillation. Methods To elucidate the prognostic value of CHADS2score in AMI patients, we analysed data of the Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET). This was a prospective and multicenter registry consisting of 3,283 AMI patients, who were hospitalized within 48-hours of onset from July 2012 to March 2014. We calculated the CHADS2 scores for 3,044 patients without clinical evidence of atrial fibrillation. The presence of heart failure was substituted by Killip classification>2 on admission. Clinical follow-up data was obtained for 3 years. In addition to the in-hospital mortality,we evaluated cardiovascular events, defined as all cause deathor non-fatal MI during 3-year follow up periods. Results In this study, enrolled patients were classified into low- (point 0–1), intermediate- (point 2–3), and high-score (point 4–6) groups by calculating CHADS2 score. Overall patients with low, intermediate and high score were divided into 1,395, 1,393 and 256 patients, respectively. In-hospital mortality among low, intermediate, and high score groups were 2.8%, 7.4% and 14.8%, respectively (P<0.001). The incidence of cardiovascular eventsamong low, intermediate, and high score groups were 7.8%, 16.3%, 29.3%, respectively (P<0.001). Kaplan-Meier analysis showed a significant difference between the groups (Figure). The event rates were significantly higher in both high score and intermediate score group than in low score group (P<0.001). Multivariate Cox hazard analysis identified CHADS2 score (per 1 point) as an independent predictor of cardiovascular events in addition to chronic kidney disease and lower body mass index. (hazard ratio, 1.344; 95% CI, 1.239–1.459; P<0.001). Among the factors constituting CHADS2 score, heart failure and age were identified as independent predictors for in-hospital mortality. With respect to the cardiovascular event during 3 years, heart failure, age, and previous stroke were revealed as significant independent predictors. Conclusion This large cohort study indicated that the CHADS2 score is useful for the prediction of in-hospital mortality and the cardiovascular events during 3-year follow up in Japanese AMI patients without atrial fibrillation.

Objective This study aimed to identify the prognostic factors of patients with first-time acute myocardial infarction (AMI) and to establish a nomogram for prognostic modeling. Methods We studied 985 patients with first-time AMI using data from the Multi-parameter Intelligent Monitoring for Intensive Care database and extracted their demographic data. Cox proportional hazards regression was used to examine outcome-related variables. We also tested a new predictive model that includes the Sequential Organ Failure Assessment (SOFA) score and compared it with the SOFA-only model. Results An older age, higher SOFA score, and higher Acute Physiology III score were risk factors for the prognosis of AMI. The risk of further cardiovascular events was 1.54-fold higher in women than in men. Patients in the cardiac surgery intensive care unit had a better prognosis than those in the coronary heart disease intensive care unit. Pressurized drug use was a protective factor and the risk of further cardiovascular events was 1.36-fold higher in nonusers. Conclusion The prognosis of AMI is affected by age, the SOFA score, the Acute Physiology III score, sex, admission location, type of care unit, and vasopressin use. Our new predictive model for AMI has better performance than the SOFA model alone.

Abstract Funding Acknowledgements Type of funding sources: None. Background The management of patients with multiple comorbidities represents a significant burden on healthcare each year. Despite requiring regular medical care to treat chronic conditions, a large number of these patients may not receive proper care. Significant disparities have been identified in patients with multiple comorbidities and those who experience acute coronary syndrome or acute myocardial infarction (AMI). Only limited data exists to identify the impact of comorbidities and utilization of primary care physician (PCP) services on the development of adverse outcomes, such as AMI. Purpose The primary objective was to analyze how PCP services utilization can be associated with comorbidities in patients who experienced an AMI. Methods This study was based on retrospective data analysis which included 250 patients admitted to the Hartford Hospital Emergency Department (ED) for an AMI. Out of these, 27 patients were excluded due to missing documentation. Collected data included age, gender, medications and recorded comorbidities, such as hypertension, hyperlipidemia, diabetes mellitus (DM), chronic kidney disease (CKD) and previous arrhythmia. Each patient was assessed regarding utilization of PCP services. Statistical analysis was performed in order to identify differences between patients with documented PCP services and those without by using the Chi-square test. Results The records allowed for identification of documented PCP services for 172 out of 223 (77.1%) patients. The most common comorbidities were hypertension and hyperlipidemia: in 165 (74.0%) and 157 (70.4%) cases respectively. The most frequent comorbidity was hypertension: 137 out of 172 (79.7%) in pts with PCP vs 28 out of 51 (54.9%) without PCP, and significantly more often in patients with PCP, p&lt; 0.001. Hyperlipidemia was the second most frequent comorbidity: in 130 out of 172 (75.6%) vs 27 out of 51 (52.9%) accordingly, and also significantly more often (p&lt; 0.002) in patients with PCP services. The number of comorbidities ranged from 0-5, including 32 (14.3%) patients without comorbidities: 16 (9.3%) with a PCP and 16 (31.4%) without PCP services. The majority of patients - 108 (48.5% of 223), had 2-3 documented comorbidities: 89 (51.8%) had two and 19 (34.6%) had three. The remaining 40 (17.9%) patients had 4-5 comorbidities: 37 (21.5%) of them with a PCP and 3 (10.3%) without, with a significant difference (p &lt; 0.001) found for patients with a higher number of comorbidities who utilized PCP services. Conclusions Our study shows that the majority of patients who presented with an AMI had one or more comorbidities. Furthermore, patients who did not utilize PCP services had fewer identified comorbidities. This suggests that there may be a significant number of patients who experienced AMI with undiagnosed comorbidities due to not having access to PCP services.

Abstract Aims To examine the effect of de-escalation of P2Y12 inhibitor in dual antiplatelet therapy (DAPT) on major adverse cardiovascular events (MACE) and bleeding complications after acute myocardial infarction (AMI) in Taiwanese patients undergoing percutaneous coronary intervention (PCI). Methods and results We retrospectively evaluated patients who had received PCI during AMI hospitalisation and were initially on aspirin and ticagrelor and without adverse events at 3 months between 2013 and 2016. In total, 1,901 and 8,199 patients were identified as switched DAPT (switched to aspirin and clopidogrel) and unswitched DAPT (continued on aspirin and ticagrelor) cohorts, respectively. With a mean follow-up of 8 months, the incidence rates (per 100 person-year) of death, AMI readmission and MACE were 2.89, 3.68 and 4.91 in the switched cohort and 2.42, 3.28 and 4.72 in the unswitched cohort, respectively based on an inverse probability of treatment weighted method. (Table) After adjustment for patients' clinical variables, two groups were no significant difference in death (A), AMI admission (B) and MACE (C). Additionally, there was no difference in the risk of major (D) or non-major clinically relevant bleeding (E) (Figure 1). Conclusions Unguided de-escalation of P2Y12 inhibitor in DAPT was not associated with higher risk of death, MACE, AMI readmission in Taiwanese patients with AMI undergoing PCI.

Objective. The pathophysiologic mechanism of how thyroid function is related to the development and prognosis of acute myocardial infarction (AMI) remains under explored, and there has been a lack of clinical investigations. In this study, we investigate the relationship between triiodothyronine (T3) level and cardiac ejection fraction (EF) as well as probrain natriuretic peptide (NT-proBNP) on admission and subsequent prognosis in AMI patients. Methods. We measured admission thyroid function, NT-proBNP, and EF by echocardiography in 345 patients diagnosed with AMI. Simple and multiregression analyses were performed to investigate the correlation between T3 level and EF as well as NT-proBNP. Major adverse cardiovascular events (MACE), including new-onset myocardial infarction, acute heart failure, and cardiac death, were documented during the follow-up. 248 participants were separated into three groups based on T3 and free triiodothyronine (FT3) levels for survival analysis during a 2-year follow-up. Results. 345 patients diagnosed with AMI were included in the initial observational analysis. 248 AMI patients were included in the follow-up survival analysis. The T3 levels were found to be significantly positively correlated with EF (R square=0.042, P<0.001) and negatively correlated with admission NT-proBNP levels (R square=0.059, P<0.001), which is the same with the correlation between FT3 and EF (R square=0.053, P<0.001) and admission NT-proBNP levels (R square=0.108, P<0.001). Kaplan-Meier survival analysis revealed no significant difference with regard to different T3 or FT3 levels at the end of follow-up. Conclusions. T3 and FT3 levels are moderately positively correlated with cardiac function on admission in AMI patients but did not predict a long-time survival rate. Further studies are needed to explain whether longer-term follow-up would further identify the prognosis effect of T3 on MACE and all-cause mortality.

Abstract Background Controversy exists regarding the use of beta-blockers (BBs) among patients with acute myocardial infarction (AMI) in contemporary reperfusion era. Previous studies predominantly focused on beta-blockers prescribed at discharge, and the effect of long-term adherence to beta-blocker on major adverse cardiovascular events (MACE) remains unclear. Objective To explore the association between long-term beta-blocker use patterns and MACE among contemporary AMI patients. Methods We enrolled 7860 patients with AMI, who were discharged alive and prescribed with BBs based on CAMI registry from January 2013 to September 2014. Patients were divided into two groups according to BBs use pattern: Always users group (n=4476) were defined as patients reporting BBs use at both 6- and 12-month follow-up; Inconsistent users group were defined as patients reporting at least once not using BBs at 6- or 12-month follow-up. Primary outcome was defined as MACE at 24-month follow-up, including all-cause death, non-fatal MI and repeat-revascularization. Multivariable cox proportional hazards regression model was used to assess the association between BBs and MACE. Results Baseline characteristics are shown in table 1. At 2-year follow-up, 518 patients in inconsistent users group (15.6%) and 548 patients in always users group (12.3%) had MACE. After multivariable adjustment, inconsistent use of BBs was associated with higher risk of MACE (HR: 1.323, 95% CI: 1.171–1.493, p<0.001). Table 1 Baseline characteristics Variable Always user (N=4476) Inconsistent user (N=3384) P value Age (years) 60.6±12.0 61.2±12.2 <0.001 Male 3381 (75.7%) 2461 (74.3%) 0.084 Diabetes 892 (20.0%) 610 (18.4%) 0.003 Hypertension 2372 (53.2%) 1543 (46.6%) <0.001 Dyslipidemia 244 (5.5%) 126 (3.8%) <0.001 Prior myocardial infarction 351 (7.9%) 232 (7.0%) <0.001 Heart failure 88 (2.0%) 63 (1.9%) <0.001 Chronic obstructive pulmonary disease 66 (1.5%) 60 (1.8%) <0.001 Current smoker 2054 (46.1%) 1579 (47.8%) 0.179 Left ventricular ejection fraction (%) 53.7±11.48 54.0±10.9 <0.001 Major Adverse Cardiovascular Events 548 (12.3%) 518 (15.6%) <0.001 Conclusions Our results showed consistent BBs use was associated with reduced risk of MACE among patients with AMI managed by contemporary treatment.
