Abstract Background and aim We have previously reported that individuals with familial hypercholesterolemia (FH) have a two-fold increased risk of acute myocardial infarction (AMI) compared with the general population. The consequences of having an AMI on re-hospitalization and mortality are however less known. The aim of the present study was to compare the risk of re-hospitalization with AMI and CHD and risk of mortality after incident (first) AMI-hospitalization between persons with and without FH (controls). Methods The original study population comprised 5691 persons diagnosed with FH during 1992–2014 and 119511 age and sex matched controls randomly selected from the general Norwegian population. We identified 221 individuals with FH and 1947 controls with an incident AMI registered in the Norwegian Patient Registry (NPR) or the Cardiovascular Disease in Norway Project during 2001–2017. Persons with incident AMI were followed until December 31st 2017 for re-hospitalization with AMI or coronary heart disease (CHD) registered in the NPR, and for mortality through linkage to the Norwegian Cause of Death Registry. Risk of re-hospitalization was compared with sub-hazard ratios (SHR) from competing risk regression with death as competing event, and mortality was compared using hazard ratios (HR) from Cox regression. All models were adjusted for age. Results Risk of re-hospitalization was 2-fold increased both for AMI [SHR=2.53 (95% CI: 1.88–3.41)] and CHD [SHR=1.82 (95% CI: 1.44–2.28)]. However, persons with FH did not have increased 28-day mortality following an incident AMI (HR=1.05 (95% CI: 0.62–1.78), but the longer-term (>28 days) mortality after first AMI was increased in FH [HR=1.45 (95% CI: 1.07–1.95]. Conclusion This study yields the important finding that persons with FH have increased risk of re-hospitalization of both AMI and CHD after incident AMI. These findings call for more intensive follow-up of individuals with FH after an AMI. Funding Acknowledgement Type of funding source: Public Institution(s).

BackgroundNo previous study has examined the effect of maternal hypothyroidism on a broad spectrum of cardiovascular disease (CVD) endpoints in the offspring.MethodsA nationwide population-based cohort study based on the linkage of several Danish nationwide registries was conducted to explore whether maternal hypothyroidism is associated with offspring’s CVD. Altogether 1,041,448 singletons born between the 1st of January 1978 and the 31st of December 1998 were investigated from the age of 8 years to the 31st of December 2016. Exposure was maternal diagnosis of hypothyroidism across lifespan and the outcome of interest was a CVD diagnosis in the offspring. Cox regression models were performed to estimate the hazard ratios (HRs) of CVD.ResultsOffspring born to mothers with hypothyroidism had an increased risk of CVD (hazard ratios (HR)=1.23, 95% confidence interval (CI): 1.12-1.35), and of several subcategories of CVD including hypertension, arrhythmia, and acute myocardial infarction in offspring. The magnitude of association was the most pronounced in an exposure occur during pregnancy (HR=1.71, 95% CI: 1.10-2.67), which is consistent across all the subgroup analysis, including sibling analysis.ConclusionsMaternal hypothyroidism is associated with an increased risk of CVD in offspring. Thyroid hormone insufficiency during pregnancy may predominantly contribute to the observed associations; however, the effects of a shared genetic background and a time-stable familial environment/lifestyle factors cannot be excluded.

Abstract Background Diuretics has been reported to have a potential for an activation of the renin-angiotensin-aldosterone system and the sympathetic nervous system, leading to a possibility of poor clinical outcome in patients with cardiovascular disease. However, few data are available on clinical impact of diuretics on long-term outcome in patients with acute myocardial infarction (AMI) based on plasma volume status. Methods To address the issue, a total of 3,416 survived patients with AMI who were registered to a large database of the Osaka Acute Coronary Insufficiency Study (OACIS) were studied. Plasma volume status was assessed with the estimated plasma volume status (ePVS) that was calculated at discharge as follows: actual PV = (1 − hematocrit) × [a + (b × body weight)] (a=1530 in males and a=864 in females, b=41.0 in males and b=47.9 in females); ideal PV = c × body weight (c=39 in males and c=40 in females), and ePVS = [(actual PV − ideal PV)/ideal PV] × 100 (%). Multivariable Cox regression analysis and propensity score matching were performed to account for imbalances in covariates. The endpoint was all-cause of death (ACD) within 5 years. Results During a median follow-up period of 855±656 days, 193 patients had ACD. In whole population, there was no significant difference in long-term mortality risk between patients with and without diuretics in both multivariate cox regression model and propensity score matching population. When patients were divided into 2 groups according to ePVS with a median value of 4.2%, 46 and 147 patients had ACD in groups with low ePVS and high ePVS, respectively. Multivariate Cox analysis showed that use of diuretics was independently associated with an increased risk of ACD in low ePVS group, (HR: 2.63, 95% confidence interval [CI]: 1.22–5.63, p=0.01), but not in high ePVS group (HR: 0.70, 95% CI: 0.44–1.10, p=0.12). These observations were consistent in the propensity-score matched cohorts; the 5-year mortality rate was significantly higher in patients with diuretics than those without among low ePVS group (4.7% vs 1.7%, p=0.041), but not among high ePVS group (8.0% vs 10.3%, p=0.247). Conclusion Prescription of diuretics at discharge was associated with increased risk of 5-year mortality in patients with AMI without PV expansion, but not with PV expansion. The role of diuretics on long-term mortality may differ in plasma volume status. Therefore, prescription of diuretics after AMI may be considered based on plasma volume status.

Abstract Background High level of Lipoprotein(a), Lp(a), is a well-recognised independent risk factor for atherosclerotic cardiovascular disease (ASCVD). However, limited data are available on the prevalence of high Lp(a) levels and on the threshold associated to coronary artery disease (CAD) burden in patients with acute myocardial infarction (MI). Methods We aim at assessing CAD burden in 651 consecutive patients hospitalized for an acute MI from January 2019 to September 2019 who underwent coronary angiography. Patients characteristics and angiographic features were compared for patients with Lp(a) <50 mg/dL (normal), ≥50 mg/dL (high) and >80 mg/dL (i.e >90th percentile) (very high). Results The prevalence of Lp(a) ≥50 mg/dL was elevated (19.0%) and 65 patients (10.0%) were in the >90th percentile. Median (IQR) age was similar across the 3 groups (normal: 68 (59–79)y; high: 74 (63–80)y; very high: 71 (57–82)y, p=0.239). When compared with patients with normal Lp(a), patients with very high levels (≥80 mg/dL) had higher prevalence of personal history of ASCVD (29 vs 16%, p=0.021) and family history of CAD (37 vs 19%, p=0.005), and were more frequently women (43 vs 29%, p=0.009). At coronary angiography, patients with very high Lp(a) levels had increased extent of CAD (Median SYNTAX score 17 (5–25) vs 10 (5–17), p=0.002) and more frequent multivessel disease (69 vs 54%, p=0.02). Conclusion Among real world patients hospitalized for an acute MI, Lp(a) levels >80 mg/dL are associated with an increased CAD burden and this threshold identifies a subset of patients with features of high ASCVD risk.

Background: The effect of hyperglycemia on outcomes in patients with acute MI (AMI) and low LVEF without diabetes mellitus is not well known. Methods: In the EPHESUS trial, of the 4411 non-DM patients, 554 had baseline hyperglycemia (≥140 mg/dL). Propensity scores for hyperglycemia were calculated for each of the 4411 patients based on 63 baseline covariates, and a greedy 1:8 matching protocol was used to match 400 and 2542 patients respectively with and without hyperglycemia. Matched Cox regression models were used to estimate associations between hyperglycemia and outcomes during 16 months of follow up. Results: Patients with hyperglycemia were more likely to be older, have higher heart rate, lower LVEF, and receive nitrates, statins, digoxin, loop diuretics, and PTCA during index admission. Unadjusted hazard ratios {HR} and 95% confidence intervals {CI} for hyperglycemia were: all-cause death (1.51; 1.22–1.87; P<0.001), cardiovascular (CV) death (1.52; 1.21–1.90; P<0.001), heart failure (HF) death (2.19, 1.46–3.29; P<0.001), all-cause hospitalization (1.23; 1.08–1.40; P=0.002), CV hospitalization (1.51, 1.24–1.84; P<0.001) and HF hospitalization (1.75; 1.37–2.25; P<0.001). In the matched cohort, hyperglycemia was significantly associated with CV death (HR=1.25, 95%CI=1.01–1.54; P=0.039), sudden cardiac death (HR=1.33; 95%CI=1.02–1.73, P=0.035) and fatal/nonfatal AMI (HR=1.53, 95%CI=1.07–2.19; P=0.04; Figure ). Conclusions: In non-diabetic post-AMI HF patients, hyperglycemia is a poor prognosticator and is associated with increased risk of fatal and non-fatal AMI, CV death, HF deaths, sudden cardiac death, and CV hospitalization.

Abstract Introduction According to the 4th Universal Definition of Myocardial Infarction (UDMI), anemia may cause acute and chronic myocardial injury indicated by elevated high-sensitive troponin (hs-cTn) concentrations, with unknown influence on triaging patients with suspected acute myocardial infarction (AMI). Purpose To investigate the influence of anemia on hs-cTnI and the diagnostic performance of the ESC 0/1 and 0/3 hour (h) algorithms. Methods Patients with suspected AMI were prospectively enrolled and stratified based on the hemoglobin (Hb) concentration at admission (females &lt;12 g/dl, males &lt;13g/dl). Hs-cTnI was measured at presentation, 1 and 3h later. Three independent cardiologists adjudicated the final diagnoses according to the 4th UDMI. Patients with ST-elevation AMI were excluded. Our primary endpoints were the safety to rule-out (negative predictive value [NPV]) and the efficacy to rule-in (positive predictive value [PPV]) AMI. Patients were followed for up to 4 years to assess all-cause mortality. Results We included 2,223 patients (64.1% males, age 65 [52; 75]) of whom 415 (18.7%) had anemia. The prevalence of AMI was numerically different for patients with and without anemia (16.4% and 12.9%, p=0.072). Hs-cTnI concentrations were significantly higher in patients with anemia and no AMI (p&lt;0.001 for baseline, 1h and 3h, respectively), but not in patients with AMI (Fig, 1A). Sex- and age-adjusted linear regression modelling in patients without AMI revealed a significant association of Hb with hs-cTnI (Beta −0.10 [95% CI: −0.14, −0.06]; p&lt;0.001; Fig. 1B). Safety and efficacy of both ESC algorithms were similar in patients with and without anemia; 0/1h (NPV 100.0% [95% CI: 94.7, 100.0]; PPV 52.7% [95% CI: 43.0, 62.3] vs. NPV 99.4% [95% CI: 98.5, 99.8]; PPV 55.7% [95% CI: 50.1, 61.1]); 0/3h (NPV 98.0% [95% CI: 95.3, 99.3]; PPV 48.4% [95% CI: 39.4, 57.5] vs. NPV 97.9 [95% CI: 97.0, 98.6], PPV 59.2 [95% CI: 53.7, 64.6]). During a median follow-up of 1.7 years and after stratification by either ESC algorithm, patients with compared to those without anemia experienced significantly worse outcome for all-cause death (p&lt;0.001; Fig. 1C). In sex-, age- and baseline hs-cTnI-adjusted Cox-regression analysis, anemia was an independent predictor for all-cause death (adjusted hazard ratio [adjHR] 3.6 [95% CI: 2.6, 5.0]), cardiovascular death (adjHR 3.0 [95% CI: 1.8, 5.2]) and rehospitalization (adjHR 1.2 [95% CI: 1.0, 1.5], but not for incidental AMI (adjHR 2.0 [95% CI: 0.8, 4.9]) or revascularization (adjHR 0.8 [95% CI: 0.5, 1.3]). Conclusion Despite the revealed association of Hb and hs-cTnI in the stable setting, the application of the ESC 0/1h and 0/3h algorithms in patients with suspected AMI and concomitant anemia is safe and provides similar efficacy. Patients with anemia experience considerable worse outcome and might therefore benefit from additional diagnostic measures and, potentially, treatment targeting anemia and its cause.

Abstract Introduction If reperfusion can be performed within 120 minutes, pPCI is the ESC guideline recommended treatment in patients with ST-elevation myocardial infarction (STEMI). Aims Historically, prognosis is dependent on time from diagnosis to reperfusion in patients with STEMI. We sought to investigate this in a contemporary patient population by assessing mortality as function of time from ECG diagnosis to sheath insertion in the Norwegian registry for invasive cardiology (NORIC). Methods NORIC, which is a part of the Norwegian Cardiovascular Disease Registry, is a national, mandatory and non-consensual person-identifiable health registry. Data from NORIC were linked with the National Population Register. Data were registered from 1st of January 2013 to 31st of June 2019. Results During this period complete data were available for n=5754 patients with 526 events. ECG diagnosis to sheath insertion was a predictor of mortality with the 4th (&gt;106 min) vs 1st quartile (&lt;54 min) with a HR of 1.74 (95% CI 1.36–2.22), p-value &lt;0.00001. The HR increased by 1.20 (95% CI 1.11–1.30) per quartile (p-value for trend &lt;0.00001). Nationally 62% percent of the patients received pPCI within the ESC recommended 90 minutes from ECG-diagnosis with large geographical variation (range 38–89%). Nationally 80% received pPCI within 115 minutes (range 75–202 minutes). Conclusion In a contemporary STEMI population, time from ECG diagnosis to sheath insertion is a strong predictor for mortality in patients admitted for pPCI for STEMI. However, the data also demonstrate large variations between different geographical health regions in Norway that should be addressed.

Abstract Aims Iatrogenic cardiac tamponades are a rare but dreaded complication of invasive electrophysiology procedures (EPs). Their long-term impact on clinical outcomes is unknown. This study analyzed the risk of death or serious cardiovascular events in patients suffering from EP related cardiac tamponade requiring pericardiocentesis during long-term follow-up. Methods and results Out of 19997 invasive EPs at our university hospital between January 1998 and September 2018, all patients with EP related periprocedural cardiac tamponade were identified (n=60) and matched (1:3 ratio) to a control group (n=180). After a follow-up of 5 years, the composite primary end point - death from any cause, acute myocardial infarction, TIA/stroke and hospitalization for heart failure – occurred in significantly more patients in the tamponade than in the control group (12 patients (20.0%) vs 19 patients (10.6%); Hazard ratio (HR) 2.53 (95% CI, 1.15–5.58); p=0.021). This was mainly driven by a higher incidence of TIA/stroke in the tamponade than in the control group (HR 3.75 (95% CI, 1.01–13.97); p=0.049). Death from any cause, acute myocardial infarction and hospitalization for heart failure did not show a significant difference between the groups. Hospitalization for pericarditis occurred in significantly more patients in the tamponade than in the control group (HR 36.0 (95% CI, 4.68–276.86); p=0.001). Conclusion Patients with EP related cardiac tamponade are at higher risk for cerebrovascular events during the first two weeks and hospitalization for pericarditis during the first months after index procedure. Despite the increased risk for early complications tamponade patients have a good long-term prognosis without increased risk for mortality or other serious cardiovascular events.

Abstract Background Serum calcium levels were reported to be associated with risk of cardiovascular diseases. The aim of this study was to analyze the association between serum calcium levels and all-cause mortality in patients with acute myocardial infarction (AMI). Methods A total of consecutive 3886 AMI patients with serum calcium data available were included in this analysis. The baseline characteristics, including clinical and laboratory parameters were collected. Patients were classified into 4 equally-sized groups based on serum calcium values (≤2.15, 2.16–2.23, 2.24–2.31, ≥2.32 mmol/L). Serum calcium tests were finished within 12 hours after admission. Patients were followed up for a median of 2.0 years (interquartile range 0.6–4.0). The primary endpoint was all-cause mortality. Results Compared to upper quartiles of serum calcium groups, subjects in the lowest quartile group (≤2.15 mmol/L) were older, lower body mass index (BMI), had lower levels of LDL-C and albumin, but higher level of NTproBNP. During a median follow-up period of 2.0 years, all-cause death occurred significantly more in the lowest quartile group (19.8%, 11.9%, 8.0% and 9.2% among the 4 groups from lowest to highest quartile, p&lt;0.001 for trend). After adjusting for potentially confounding variables, the Cox analysis revealed that low serum calcium levels independently predict subsequent all-cause mortality (OR=0.36, 95% CI: 0.18–0.73), and identified that older age, lower BMI, smoking, and higher levels of creatinine were also independently associated with increased risk of mortality. Conclusion Low serum calcium levels on admission independently predict mortality in patients with AMI. Further studies are required to determine whether calcium supplementation could improve outcomes in AMI patients with hypocalcemia. Funding Acknowledgement Type of funding source: Foundation.

Abstract Background The prevalence and prognosis of familial hypercholesterolemia (FH) with acute myocardial infarction (AMI) in China is unclear. Purpose To invistigate the prevalence and prognosis of familial hypercholesterolemia (FH) with acute myocardial infarction (AMI) in China. Methods In China Acute Myocardial Infarction (CAMI) Registry, 13,002 patients with age 18–80 were consecutively enrolled with first-onset acute myocardial infarction who were naïve to statin before admission from Januanry 1st, 2013 to October 31st, 2014. According to Dutch Lipid Clinical Network Criteria (DLCNC), the patients were divided to heterozygous familial hypercholesterolemia (HeFH) (definite or probable HeFH, possible HeFH) or no HeFH group. All the patients were followed up (average follow-up period, 24 months) and composite major adverse cardiovascular events (ENDPOINT) were recorded which were defined as all-cause death, non-fatal myocardial reinfarction and stroke. Cox regression was performed to analyze the difference of composite endpoint occurrence between HeFH group and no HeFH group. Results The number of the patients in the three groups was as following, 62 in definite or probable HeFH group, 484 in possible HeFH group, 12456 in no HeFH group. The prevalence of HeFH is 4.2% (including 0.47% of definite or probable HeFH, 3.73% of possible FH). The average age of onset of first-time AMI was 54±12,56±12,63±12 years old (p<0.0001) in definite or probable HeFH group, possible HeFH group and no HeFH group, respectively. The percentage of Killip III or above (8.1% vs 4.3% vs 6.3%, p=0.1629), cardiac arrest (1.6% vs 0.6% vs 0.9%, p=0.6990), and TIMI 0–2 grade after primary percutaneous cardiac intervention (PCI) (0% vs 6.8% vs 4.3%, p=0.5866) was not significantly different in definite or probable HeFH group, possible HeFH group and no HeFH group, respectively. After Cox proportional analysis adjusting multiple factors, the rate of composite endpoint during follow-up period was not significantly different (definite or probable HeFH group vs no HeFH group, HR 0. 853, 95% CI 0.381–1.910, p=0.699, possible HeFH group vs no HeFH group, HR1.076, 95% CI 0.795–1.458, p=0.635). The prognosis of FH with AMI in China Conclusions In CAMI Registry, the prevalence of HeFH was 4.2%, the diagnosis of HeFH was not a dependent risk factor for the rate of composite cardiovascular events.
