Background: Little is known about the association between coronary artery disease (CAD) and the risk of heart failure (HF) after myocardial infarction (MI), and whether it differs by reduced (HFrEF) or preserved (HFpEF) ejection fraction (EF) has yet to be determined. Subjects and Methods: Olmsted County, Minnesota residents (n=1,924; mean age, 64 years; 66% male) with first MI diagnosed in 1990-2010 and no prior HF were followed through 2013. Framingham Heart Study criteria were used to define HF, which was further classified according to EF (applying a 50% cutoff). The extent of angiographic CAD was defined at index MI according to the number of major epicardial coronary arteries with ≥50% lumen diameter obstruction. Fine & Gray and Cox proportional hazards regression models were used to assess the association of CAD categories with incidence of HF, and multiple imputation methodology was applied to account for the 19% with missing EF data. Results: During a mean (SD) follow-up of 6.7 (5.9) years, 594 patients developed HF. Adjusted for age and sex, with death considered a competing risk, the cumulative incidence rates of HF among patients with 1- (n=581), 2- (n=622), and 3-vessel disease (n=721) were 11.2%, 14.6% and 20.5% at 30 days; and 18.1%, 22.3% and 29.4% at 5 years after MI, respectively. The increased risk of HF with greater number of occluded vessels was only modestly attenuated after further adjustment for patient and MI characteristics, and did not differ materially by EF (Table). Conclusions: The extent of angiographic CAD expressed by the number of diseased vessels is independently associated with HF incidence after MI. The association is evident promptly after MI and applies to both HFrEF and HFpEF.

Objectives. To evaluate whether serum interleukin-6 (IL-6) is associated with increased risk of mortality in coronary artery disease (CAD) patients.Methods. We performed a prospective cohort study of 718 CAD patients from the Guangzhou Cardiovascular Disease Cohort (GCDC) study. Multivariable-adjusted Cox proportional hazards regression analyses were used to examine the association between serum IL-6 with all-cause and cardiovascular mortality.Results. During the 1663 person-years of followup, the cumulative all-cause mortality and cardiovascular mortality were 6.5% (n=47) and 3.3% (n=24), respectively. The mean length of followup was2.32±0.81years. In the multivariable analyses, a one-SD increment in log-transformed serum IL-6 was positively associated with an increased risk of all-cause and cardiovascular mortality, with hazard ratios (HR) of 2.93 (95% CI, 2.11–4.08) and 2.04 (95% CI, 1.34–3.68) within the patients combined and 2.98 (95% CI, 2.12–4.18) and 3.10 (95% CI, 1.98–4.85) within males, respectively. Patients in the highest serum IL-6 tertile versus the lowest tertile were at higher risk of all-cause and cardiovascular mortality, with HR of 17.12 (95% CI 3.11–71.76) and 8.68 (95% CI, 1.88–37.51), respectively.Conclusions. In hospitalized patients with CAD, serum IL-6 is significantly associated with all-cause and cardiovascular mortality.

Abstract: Introduction: There are conflicting data on the prevalence and prognosis of AMI patients with non-obstructive coronary artery disease (MINOCA). Aim: We studied the prevalence and prognosis of MINOCA patients. Method: In the Hungarian Myocardial Infarction Registry (HUMIR) 45,223 patients (pts) with acute myocardial infarction (AMI) were found who were treated between Jan 1, 2014, and June 30, 2018, and coronary arteriography was performed. ST-elevation myocardial infarction was diagnosed in 22,469 pts (49.7%). Patients without obstructive coronary artery disease who had no previous myocardial infarction, heart failure, PCI and CABG procedure were selected to the MINOCA group (n = 2003). Patients with obstructive coronary artery disease belonged to the MICAD group (n = 43,220). We investigated clinical characteristics of the patients, overall survival and reinfarction. Survival curves were estimated with the Kaplan–Meier method and were modeled with the Cox proportional hazards model. Results: The proportion of MINOCA pts among all myocardial infarction was by 4.4% higher in the STEMI pts compared to the NSTEMI group (2.0% vs. 6.8%). The MINOCA pts were younger (age 64.0 ± 14.4 vs. 65.5 ± 12.2 years), and the proportion of women was higher (55.7% vs. 36.5%). Hypertension, diabetes mellitus and peripheral artery disease were more common in the MICAD group (79.1% vs. 73.7%, 33.0% vs. 21.2%, and 12% vs. 8%). The mortality was higher among the MICAD pts. In the MINOCA group, the mortality of men did not differ between STEMI and NSTEMI, as opposed to women: women with STEMI had higher mortality than women with NSTEMI. The risk of reinfarction was higher in the MICAD group, especially in NSTEMI, the risk in the MINOCA group was lower, and there was no substantial difference between types. Conclusion: In this real word, retrospective, observational study, we found a significant difference in the prevalence of MINOCA pts according to different types of myocardial infarction. In the MINOCA group, the mortality of women with STEMI was substantially higher. Orv Hetil. 2019; 160(45): 1791–1797.

Introduction: The atherogenicity of residual cholesterol (RC) has been underlined by recent guidelines, which was linked to coronary artery disease (CAD), especially for patients with diabetes mellitus (DM). Hypothesis: This study aimed to examine the prognostic value of plasma RC, clinically presented as triglyceride-rich lipoprotein-cholesterol (TRL-C) or remnant-like lipoprotein particles-cholesterol (RLP-C), in CAD patients with different glucose metabolism status. Methods: Fasting plasma TRL-C and RLP-C levels were directly calculated or measured in 4331 patients with CAD. Patients were followed for incident MACEs for up to 8.6 years and categorized according to both glucose metabolism status [DM, pre-DM, normal glycaemia regulation (NGR)] and RC levels. Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence intervals. Results: During a mean follow-up of 5.1 years, 541 (12.5%) MACEs occurred. The risk for MACEs was significantly higher in patients with elevated RC levels after adjustment for potential confounders. No significant difference in MACEs was observed between pre-DM and NGR groups (p>0.05). When stratified by status of glucose metabolism and RC levels, highest levels of RLP-C, calculated and measured TRL-C were significant and independent predictors of developing MACEs in pre-DM (HR: 2.10, 1.98, 1.92, respectively; all p<0.05) and DM (HR: 2.25, 2.00, 2.16, respectively; all p<0.05). Conclusions: In this large cohort study with long-term follow-up, data firstly demonstrated that higher RC levels were significantly associated with the worse prognosis in DM and pre-DM patients with CAD, suggesting RC might be a target for patients with impaired glucose metabolism.

Objectives: To investigate whether serum fibroblast growth factor 21 (FGF21) levels can be used to predict the future development of major adverse cardiovascular events (MACEs). Methods: This study included 253 patients who received subsequent follow-up, and complete data were collected for 234 patients. Independent predictors of MACEs were identified by using the Cox proportional-hazards regression analysis. The prognostic value of FGF21 levels for MACEs was evaluated by Kaplan-Meier survival analysis. Results: Of 229 patients finally enrolled in the analysis, 27/60 without coronary artery disease (CAD) at baseline experienced a MACE, and 132/169 patients with CAD at baseline experienced a MACE. Among patients with CAD at baseline, serum FGF21 levels were significantly higher in patients with MACEs (p < 0.05) than in patients without MACEs. Kaplan-Meier survival analysis showed patients with a higher serum FGF21 had a significantly lower event-free survival (p = 0.001) than those with a lower level. Further Cox proportional-hazards regression analysis, including the traditional risk factors for cardiovascular disease, showed that serum FGF21 was an independent predictor of MACE occurrence. Conclusions: In patients with CAD at baseline, an elevated serum FGF21 level was associated with the development of a MACE in the future.

Abstract Background In patients undergo PCI for coronary artery disease, target lesion calcification is associated with major cardiac events. Malnutrition is the important factor to cause frailty and sarcopenia which affect prognosis of cardiovascular diseases. However, the relationship between morphology in target lesions and malnutrition in patients undergo PCI is still uncertain. Purpose The aim of the present study was to investigate how malnutrition affects prognosis of stable angina patients underwent PCI and morphology in target lesions. Methods The subject was 206 consecutive stable angina patients undergone successful PCI using second-generation drug eluting stents and intravascular ultrasound (IVUS). The study patients were divided into two groups based on malnutrition or non-malnutrition. Nutritional status was assessed by Geriatric Nutritional Risk Index (GNRI), and patients with GNRI&lt;92 at admission were defined as malnutrition group (MG). We investigated the association between malnutrition on admission and outcome, and morphology in target lesions assessed by IVUS. Target lesion morphology were divided into moderate/severe calcified group and none/mild calcified group. Results All-cause death and MACCE (major cardiovascular and cerebrovascular events) ≤3 years after PCI were 15 cases (7%) and 33 cases (16%). MG had higher rate of all-cause death (20 vs. 6%, p=0.001) and MACCE (37 vs. 10%, p&lt;0.001) than those of non-MG. Kaplan Meier analysis elucidated that survival rate was significantly lower in MG compared to that in non-MG (p&lt;0.001). As a result of cox proportional hazards analysis, all-cause death was associated with age [hazard ratio (HR): 1.05, 95% confidence interval (CI): 1.01–1.10, p=0.006)], hs-CRP (HR: 1.03, 95% CI: 1.03–1.12, p&lt;0.001), hemodialysis (HR: 2.25, 95% CI: 1.08–4.68, p=0.029), left ventricular ejection fraction (LVEF) (HR: 0.97, 95% CI: 0.95–0.99, p=0.017) and malnutrition (HR: 4.38, 95% CI: 2.11–9.09, p&lt;0.001) in the univariate analysis. Similarly, cox proportional hazards analysis revealed that age (HR: 1.04, 95% CI: 1.01–1.07, p=0.018), hs-CRP (HR: 1.08, 95% CI: 1.03–1.11, p&lt;0.001), hemodialysis (HR: 2.68, 95% CI: 1.45–4.94, p=0.002), LVEF (HR: 0.97, 95% CI: 0.95–0.99, p=0.002) and malnutrition (HR: 4.14, 95% CI: 2.23–7.67, p&lt;0.001) were significantly associated with MACCE. Multivariate analysis for all-cause death and MACCE revealed that malnutrition was an independent risk factor (HR: 3.47, 95% CI: 1.52–7.94, p=0.003, HR: 3.76, 95% CI: 1.87–7.58, p&lt;0.001). Furthermore, MG was significantly associated with moderate/severe target calcified lesions assessed by IVUS compared to those of patients in non-MG (67 vs. 27%, p&lt;0.001) regardless with or without hemodialysis. Conclusions Malnutrition was a crucial independent risk factor for stable angina patients who underwent PCI and was significantly associated with moderate/severe target calcified lesions.

Abstract Background Women with signs and symptoms of ischemia but no obstructive coronary artery disease (INOCA) are at increased risk of developing heart failure with preserved ejection fraction (HFpEF); however, the exact mechanism for HFpEF progression remains to be elucidated. Prior studies have focused specifically on impaired left ventricular diastolic function in INOCA. We hypothesized that extending our evaluation to include the left atrium (LA)– a key constituent of the transmitral pressure gradient and left ventricular filling– would provide additional, novel, pathophysiological insight. Purpose To evaluate LA function in women with INOCA using cardiac MRI (CMR). Methods We performed retrospective feature tracking analysis of cine images from CMR (Figure 1A), to evaluate LA strain, in 58 INOCA women with normal sinus rhythm (three were excluded due to suboptimal image quality). All strain measurements were performed in duplicate by an experienced investigator blinded to clinical status. We subdivided the cohort by an established threshold of resting left ventricular end diastolic pressure (LVEDP) <12 mmHg vs >12 mmHg, performed invasively within a median of 27 days of the CMR. As illustrated in Figure 1B, LA function was divided into three established phases: (1) reservoir strain, passive expansion of the left atrium from the pulmonary circulation while the mitral valve is closed; (2) conduit strain, passive emptying of the atrium into the ventricle; and (3) booster strain, active emptying of the left atrium following atrial depolarization. Results Reservoir strain was higher in the elevated LVEDP group (n=20, 26.1 + 1.3%) vs. not elevated group (n=35, 22.8 + 0.9%, p=0.03; Figure 1C). In contrast, we observed no group difference in conduit strain (16.5 + 1.0 and 16.5 + 0.7, p=0.78, respectively; Figure 1D), resulting in significantly higher atrial booster strain in the elevated LVEDP group (10.0 + 1.1% and 7.0 + 0.6, p<0.01, respectively; Figure 1E). Conclusions To our knowledge, this is the first report of LA function in women with INOCA. That reservoir strain was higher in subjects with elevated LVEDP provides important pathophysiologic insight regarding diastolic hemodynamics of the LA. The similar conduit function between groups– despite different LVEDP's– strongly suggests a ventricular contribution to the impaired transmitral pressure gradient. Together, these initial proof-of-concept data support the evaluation of LA function in our quest to better understand heart failure progression in INOCA.

Abstract Diabetes is known to be a major cardiovascular risk factor associated with significantly increased morbidity and mortality and particularly increased risk of major cardiac events especially myocardial infarction as a manifestation of highly incident coronary artery disease (CAD).This can lead to decreased life expectation and life quality. Major cause for myocardial infarction is plaque rupture. Prevalence of obstructive and non-obstructive plaques is increased in diabetic patients. Background and Objectives The prevalence of coronary heart disease in diabetic patients compared to non- diabetics and evaluating the composition of the plaque in diseased individuals in both groups by usage of multislice computed tomography (MSCT) angiography . Subjects and Methods A total of 80 consecutive MSCT angiography examinations were performed between August 2017 and June 2018. Of these, the patients were evaluated for the presence and type of atherosclerotic plaque and severity of luminal narrowing. Results Eighty (40 in the diabetic group and 40 in the non-diabetic group) patients underwent MSCT angiography with DM prevalence of 0.212 (95% Cl for AOR 0.056 -1.896). Among them, 20 patients (50 %) in the diabetic group and 14 patients (35 %) in the non-diabetic group had +ve coronary heart disease, 33.3 % had significant and moderately significant coronary narrowing on diabetic group and 31.3 % in non-diabetic group on MSCT angiography. Diabetic patients had more soft plaque compared with non-diabetic patients. Conclusion DM is not an independent factor for the disease occurrence in coronary artery disease but is a dependent factor in the association of other risk factors such as smoking ,hypertension and dyslipidemia.
