BACKGROUND: Evaluating the independent effects of psychosocial and physiological factors on survival of cardiac patients is difficult because it requires obtaining extensive physiological and psychosocial data and long-term follow-up of high-risk patients. OBJECTIVES: To examine the independent contributions of psychosocial and physiological status to survival of patients who had had myocardial infarction. METHODS: The sample consisted of 348 patients in the Cardiac Arrhythmia Suppression Trial who had asymptomatic ventricular arrhythmias after myocardial infarction. Psychosocial status was assessed with the Social Support Questionnaire-6, Social Readjustment Rating Scale, State-Trait Anxiety Inventory, Self-Rating Depression Scale, Jenkins Activity Survey, and Expression of Anger Scale. Physiological data included measurement of left ventricular ejection fraction; history of previous myocardial infarction, congestive heart failure, and diabetes; and results of Holter monitoring. RESULTS: At the first follow-up, after the effect of the physiological predictors was controlled for, psychosocial factors were significant independent predictors of survival. Among men in the nonactive medication group (n = 263), higher state anxiety, lower anger outward, more past life events, and lower expectations of future life events were predictors of mortality. Data suggested that the relationship of anger to mortality might differ for men and women. Increases in past life events and depression from baseline to first follow-up were greater among those who died than among those who lived. CONCLUSION: Among patients who had asymptomatic ventricular arrhythmias after myocardial infarction, psychological status during the period after infarction contributed to mortality beyond the effect of physiological status. The results reaffirm the critical interrelationship between mind and body for cardiovascular health.

Background: Relatively high left ventricular ejection fraction (EF) (>65%) in women was recently associated with higher all-cause mortality over 6 years follow-up in the CONFIRM study. We sought to evaluate high EF and major adverse cardiovascular events (MACE) in the Women’s Ischemia Syndrome Evaluation (WISE) study. Methods: The WISE original cohort (enrolled 1996-2000) is a multicenter prospective study of women with suspected ischemic heart disease undergoing clinically indicated invasive coronary angiography. We investigated the relationship between high (>65%) and normal (55-65%) EF and MACE, defined as all-cause death, nonfatal myocardial infarction (MI), stroke and heart failure (HF) hospitalization using Kaplan Meier (KM) and regression analyses. Results: A total of 653 women were included (298 high and 355 normal EF). Mean age was 58±11 years and mean EF was 68±7%. There was no significant difference in MACE by EF group over a 10-year follow-up period (log rank p=0.54, Figure ). When patients were stratified by the presence of obstructive CAD, MACE rates remained similar between high and normal EF. High EF was not associated with stroke or HF but had a lower MI risk (log rank p=0.03, Table ). EF was not associated with MACE in a multivariable regression model. Conclusions: Among women presenting with evidence of ischemia, there was no significant difference in MACE between high and normal EF groups. High EF was associated with a lower risk of myocardial infarction as an individual component of MACE.

Abstract Introduction The CARISMA trial was the first study to use continuous monitoring for documentation of long-term arrhythmias in post-infarction patients with left ventricular dysfunction. During the study duration (2000–2005), primary PCI (pPCI) as treatment of acute myocardial infarction was introduced approximately midway (2002) on the enrolling centres. Purpose The aim of this study was to describe the influence of mode of revascularization after myocardial infarction (AMI) on long-term risk of risk of new onset atrial fibrillation, ventricular tachyarrhythmias and brady arrhythmias. Methods The study is a sub-study on the CARISMA study population that consisted of patients with AMI and left ventricular ejection fraction ≤40%, which received an implantable loop recorder and was followed for 2 years. After exclusion of 15 patients who refused device implantation and 26 with pre-existing arrhythmias, 268 of the 312 patients were included. Choice of revascularization was made by the treating team independently of the trial and was retrospectively divided into primary percutaneous intervention (pPCI), subacute PCI (24 hours to 2 weeks after AMI), primary thrombolysis or no revascularization. Endpoints were new-onset of arrhythmias and major cardiovascular events (MACE). The Kaplan-Meier (figure 1) and Mantel-Byar methods were used for time to first event risk analysis. Results A total of 77 patients received no revascularization, whereas 49 received thrombolysis only and 142 received PCI. At two-years follow up patients treated with any PCI had a significant lower risk (0.40, n=63) of any arrhythmia compared to patients treated with trombolysis (0.60, n=30) or no revascularization (0.68, n=16) (p<0.001, unadjusted) (figure 1). Risk of MACE was significant higher in patients with any arrhythmia (0.25, n=76) compared to no arrhythmia (0.11, n=93) at two years follow-up (p=0.004, unadjusted). Figure 1 Conclusion(s) The long-term risk of new onset arrhythmias after AMI was significantly lower in patients treated with any PCI compared to patients not revascularized or treated with thrombolysis. Risk of MACE was significantly higher in patients with new onset arrhythmias compared to patients with no arrhythmias.

Abstract Background Truncating genetic variants in titin (TTNtv) are identified in 15–25% of patients with primary dilated cardiomyopathy (DCM). Previous genotype/phenotype studies have reported conflicting results regarding disease severity and pathologic features associated with TTNtv. Purpose To investigate the natural history, reversibility and burden of arrhythmias associated with TTNtv in a Danish cohort with long-term follow-up. Methods Patients with DCM, recruited from two Danish tertiary centers, were included based on the presence of a TTNtv in a cardiac expressed titin exon. Data on patients' medical history including symptoms, demography, family history, comorbidities, treatment, ECG features, and echocardiograms were registered. Outcome data including all-cause mortality, need of heart transplantation (HTX) or left ventricular assist device (LVAD), and presence of ventricular and supraventricular arrhythmias were registered. Left ventricular reverse remodeling (LVRR) was defined as an absolute increase in left ventricular ejection fraction (LVEF) ≥10% points or normalization. Results A total of 104 patients (71 men, 69%; 72 probands) with definite TTNtv-DCM were included. The mean age at DCM diagnosis was (mean±SD) 45±13 years (43±13 for men; 49±14 for women, p<0.04) and median follow-up was 8.1 years. The mean LVEF was 28±13% at time of diagnosis (26±12% for men; 30±13% for women, p=0.173). During follow-up, 31 patients (30%; 24 men) died or needed HTX/LVAD. Medical therapy was associated with LVRR in 79% of patients 3.6 years after diagnosis. LVRR was maintained long-term in 64% of patients. Women had a better response to medical therapy compared to men (mean LVEF increase 19%; vs 15% in men, p<0.04). Atrial fibrillation/flutter was observed in 40% of patients and ventricular arrhythmias in 23% of patients. Men had an earlier occurrence of both supraventricular and ventricular arrhythmias (p=0.005) with half of the men having experienced an arrhythmia at the age of 54 years. Freedom from arrhythmias with age Conclusion TTNtv leads to a DCM phenotype associated with a marked gender-difference in age at DCM diagnosis and high burden of both supraventricular and ventricular arrhythmias. Importantly, the DCM-TTNtv phenotype was associated with a high degree of reversibility of systolic function following medical therapy.

Abstract Background: Admission hyperglycemia has been associated with major adverse cardiovascular and cerebrovascular events (MACCEs) in patients with acute coronary syndrome. Methods: In this study we sought to determine the association between admission blood sugar (ABS) and the outcomes of non-diabetic patients with first-ever acute myocardial infarction (MI). Non-diabetic patients with MI were evaluated from March 2016 to March 2019. Baseline characteristics, laboratories, electrocardiogram, and baseline left ventricular ejection fraction (LVEF) were recorded. All patients were followed up and outcomes were obtained. Follow-up data comprised of repeating electrocardiogram and echocardiography at 1 year, and MACCE, including re-MI, stroke, and mortality. Results: A total of 312 patients with a mean age of 54.2 ± 11.9 years were evaluated. All patients were followed up for a median of 38 months. The frequencies of in-hospital mortality and MACCE at late follow-up were higher in third tertile of ABS compared with those in first and second tertiles (both p <0.05). Based on the Cox regression analysis, the independent predictors of MACCE included age (hazard ratio [HR] 1.068, 95% confidence interval [CI] 1.033 – 1.105, p <0.001), third tertile of ABS >172 mg/dL (HR 21.257, 95% CI 2.832 – 159.577, p=0.003), and baseline LVEF (HR 0.947, 95% CI 0.901 – 0.995, p=0.031). Conclusion: Admission stress hyperglycemia is associated with increased rates of in-hospital mortality and MACCE at late follow-up in non-diabetic patients with MI. Moreover, elevated ABS, older ages, and a decreased value of baseline LVEF predicted MACCE during follow-up.

Abstract Background Severely reduced left ventricular ejection fraction (LVEF≤35%) is commonly seen in approximately 5% of the myocardial infarction (MI) survivors in its acute-phase, which is recognized as a risk factor of post-MI cardiac death. However, clinical impact of the progressively reduced LVEF in the chronic-phase after MI has not been clarified. Purpose To evaluate clinical impact of the progressively reduced LVEF in the chronic-phase after MI. Method We evaluated 1659 consecutive patients with acute MI by serial echocardiography. Primary outcome was severely reduced LVEF. And secondary outcome was all cause death and cardiac death. Result During follow-up (median: 1097 days), severely reduced LVEF newly developed in 8.6% of AMI survivors. These patients had significantly higher incidence of all cause death (20.7% vs. 4.4%, p<0.01) and cardiac death (10.6% vs. 1.2%, p<0.01) than those with LVEF>35%. Severely reduced LVEF progressed in the chronic-phase associated with all cause death and cardiac death as well as those with severely reduced EF in the acute-phase. Figure 1 Conclusions Progressively reduced LVEF during chronic-phase occurred 8.6% per 10-year in MI survivors. Careful long-term follow-up after MI should be needed to identify possible candidate for the implantable cardioverter-defibrillator.

Abstract Background Aortic valve stenosis (AS) is associated with the presence and severity of coronary artery disease independently of clinical risk factors, which leads to increased cardiovascular mortality. However, the prevalence of AS and its prognostic value among patients with acute myocardial infarction (AMI) remain unknown. Purpose The purpose of this study was to investigate the prevalence and prognostic impact of AS in AMI patients. Methods We studied 2,803 AMI patients using data from Mie ACS registry, a prospective and multicenter registry. Patients were divided into subgroups according to the presence and severity of AS based on maximal aortic flow rate by Doppler echocardiography before hospital discharge: non-AS <2.0 m/s, 2.0 m/s≤mild AS <3.0 m/s, 3.0 m/s≤moderate AS <4.0m/s and severe AS≥4.0 m/s. The primary outcome was defined as 2-year all-cause mortality. Results AS was detected in 79 patients (2.8%) including 49 mild AS, 23 moderate AS and 6 severe AS. AS patients were significantly older (79.9±9.8 versus 68.3±12.6 years), and higher killip classification than non-AS patients (P<0.01, respectively). However, left ventricular ejection fraction, and prevalence of primary PCI was similar between the 2 groups. During the follow-up periods (median 725 days), 333 (11.9%) patients experienced all-cause death. AS patients demonstrated the higher all-cause mortality rate compared to that of non-AS patients during follow up (47.3% versus 11.3%, P<0.0001, chi square). Kaplan-Meier curves showed that the probability of all-cause mortality was significantly higher among AS patients than non-AS patients, and was highest among moderate and severe AS (See figure A and B). Cox regression analyses for all-cause mortality demonstrated that the severity of AS was the strongest and independent poor prognostic factor (HR 1.71, 95% CI 1.30–2.24, P<0.001, See table). Cox hazard regression analysis Hazard ratio 95% Confidential interval P-value Severity of aortic valve stenosis 1.71 1.30–2.24 <0.001 Killip classification 1.63 1.46–1.82 <0.001 Age 1.07 1.06–1.09 <0.001 Serum creatinine level 1.05 1.03–1.08 <0.001 Max CPK level 1.00 1.00–1.01 <0.001 Left ventricular ejection fraction 0.96 0.95–0.97 <0.001 Primary percutaneous coronary intervention 0.67 0.47–0.96 0.03 CPK suggests creatinine phosphokinase. All cause mortality Conclusions The presence of AS of any severity contributes to worsening of patients' prognosis following AMI independently of other known risk factors.
