Heart failure during acute coronary syndrome and the long-term cancer risk: the ABC-9 Study on heart disease.

AIMS: A higher risk of cancer among patients with heart failure (HF) has been suggested in recent community-based studies. This study aimed to investigate the impact of HF during hospitalization with acute coronary syndrome (ACS) on the long-term cancer risk. METHODS AND RESULTS: The study included 572 patients admitted with ACS to three Italian hospitals, discharged cancer-free, and prospectively followed for 24 years or until death. All but three patients completed the follow-up, which represented 6440 person-years (mean age: 66 ± 12 years; 70% males). Baseline HF was diagnosed in 192 (34%) patients. A total of 129 (23%) patients developed cancer (103 without HF and 26 with HF), and 107 (19%) patients died due to it (81 without HF and 26 with HF). The incidence rates for cancer onset and cancer death were not different according to HF status. Cox regression analysis revealed no association between HF or left ventricular ejection fraction (LVEF) and cancer risk. In addition, no difference in cancer risk was observed among patients with HF with preserved ejection fraction, HF with mildly reduced ejection fraction, and HF with reduced ejection fraction. In competing risk regression analysis, the risk of cancer onset associated with HF was sub-hazard ratio (SHR) 0.47 [95% confidence interval (CI): 0.30-0.72; P = 0.001] and SHR 1.02 (95% CI: 1.01-1.04; P = 0.002) with LVEF. Results were the same in the adjusted model. Yet the fully adjusted model showed an attenuated association between cancer death and HF (SHR: 0.63; 95% CI: 0.37-1.05; P = 0.08) and LVEF (SHR: 1.02; 95% CI: 0.99-1.06; P = 0.08). Consistent results were obtained after using propensity score matching analysis that created 192 pairs. A negative interaction between age and HF and a positive interaction between age and LVEF for cancer risk have also been found. CONCLUSIONS: An inverse association between baseline HF and long-term cancer risk has been observed among the ABC Study on heart disease patients who were followed for 24 years after ACS.

Microalbuminuria during acute coronary syndrome: Association with 22-year mortality and causes of death. The ABC-8* study on heart disease. (*ABC is an acronym for Adria, Bassano, Conegliano, and Padova Hospitals).

BACKGROUND: Microalbuminuria is associated with adverse outcomes in acute coronary syndrome (ACS) patients. METHODS: To evaluate the very long-term association between Microalbuminuria and the overall mortality and causes of death in this clinical setting, we prospectively studied 579 unselected ACS patients admitted to three hospitals. The baseline albumin-to-creatinine ratio (ACR) was measured on days 1, 3, and 7 in 24-h urine samples. Patients were followed for 22 years or until death. RESULTS: Virtually all patients completed follow-up; 449(78%) had died: 41% due to non-sudden cardiac death (non-SCD), 19% sudden cardiac death (SCD), 40% due to non-cardiac (non-CD) death. Using unadjusted Cox regression analysis, ACR was a significant predictor of all-cause mortality (hazard ratio [HR] 1.26;95%confidence interval [CI] 1.22-1.31; p˂0.0001) and the three causes of death (HR 1.40;95%CI 1.32-1.48; p˂0.0001), (HR 1.22;95%CI 1.12-1.32; p˂0.0001) and (HR 1.16;95%CI 1.09-1.23; p˂0.0001) for non-SCD, SCD and non-CD respectively. Using a fully adjusted model, ACR was a significant independent predictor of all-cause mortality (HR 1.12; 95%CI 1.08-1.16; p˂0.0001) and only non-SCD (HR 1.21; 95%CI 1.14-1.29; p˂0.0001). There was a positive interaction between ACR level and history of AMI (HR 1.15; 95%CI 1.03-1.29; p = 0.01) and the presence of heart failure at admission (HR 1.11; 95%CI 1.01-1.24; p = 0.04), and negative interaction with higher than median LVEF (HR 0.89; 95%CI 0.80-0.99; p = 0.03) for all-cause mortality at the multivariable level. CONCLUSION: Based on the present analysis, baseline urinary albumin excretion during ACS is a strong independent predictor of the very long-term mortality risk, chiefly due to non-sudden cardiac death.

Differences in Cancer Death Risk Long After ACS Among Selected Urban and Rural Areas in North Italy: The ABC-7a Study on Heart Disease.

BACKGROUND: An increased risk of cancer death has been demonstrated for patients diagnosed with acute coronary syndrome (ACS). We are investigating possible geographic risk disparities. METHODS: This prospective study included 541 ACS patients who were admitted to hospitals and discharged alive in three provinces of Italy's Veneto region. The patients were classified as residing in urban or rural areas in each province. RESULTS: With 3 exceptions, all patients completed the 22-year follow-up or were followed until death. Urban (46%) and rural (54%) residents shared most of their baseline demographic and clinical characteristics. Pre-existing malignancy was noted in 15 patients, whereas 106 patients developed cancer during the follow-up period, which represented 6232 person-years. No difference in the cancer death risk was found between the urban and rural areas or between southern and northern provinces (hazard ratio [HR] 1.1; 95% confidence interval [CI] 0.7-1.7; p = 0.59 and HR 1.1; 95% CI 0.9-1.4; p = 0.29, respectively) according to the unadjusted Cox regression analysis. Geographic areas, however, showed a strong positive interaction, with risk increasing from the urban to rural areas from southern to northern provinces (HR 1.9; 95% CI 1.1-3.0; p = 0.01). The fully adjusted Cox regression and Fine-Gray competing risk regression models provided similar results. Interestingly, these results persisted, and even strengthened, after exclusion of the 22 patients who developed malignancy and survived to the end of follow-up. We did not observe an urban/rural difference in non-neoplastic death risk or a significant interaction between the geographic areas. CONCLUSION: Our analysis reveals that the cancer death risk among unselected ACS patients in Italy's Veneto region significantly differs by geography. The northern rural area has the highest risk. These results highlight the importance of implementing a preventive policy based on area-specific knowledge.

Risk of malignancy long after acute coronary syndrome in selected urban and rural areas and comparison with smoking risk: the ABC-7* study on Heart Disease.

BACKGROUND: Increased cancer risk has been reported in patients with acute coronary syndrome (ACS). OBJECTIVES: To investigate geographic differences in risk malignancy long after ACS. METHODS: We enrolled 586 ACS patients admitted to hospitals in three provinces in the Veneto region of Italy in this prospective study. Patient's residency was classified into three urban and three nearby rural areas. RESULTS: All (except for 3) patients completed the follow-up (22 years or death) and 54 % were living in rural areas. Sixteen patients had pre-existing malignancy, and 106 developed the disease during follow-up. Cancer prevalence was 17 % and 24 % (p = 0.05) and incidence of malignancy was 16 and 21/1000 person-years for urban and rural areas, respectively. In unadjusted logistic regression analysis, cancer risk increased from urban to rural areas (odds ratio [OR] 3.4;95 % confidence interval [CI] 1.7-7.1; p = 0.001), with little change from north to south provinces (OR 1.5;95 % CI 1.0-2.2; p = 0.06). Yet, we found a strong positive interaction between urban-rural areas and provinces (OR 2.1;95 % CI 1.2-3.5; p = 0.003). These results kept true in the fully adjusted model. Unadjusted Cox regression analysis revealed increasing hazards ratios (HRs) for malignancy onset from urban to rural areas (HR 3.0;95 % CI 1.5-6.2; p = 0.02), but not among provinces (HR 1.3;95 % CI 1.0-2.0; p = 0.14). Also, we found a strong positive interaction between geographic areas (HR 2.1;95 % CI 1.3-3.5; p = 0.002), even with a fully adjusted model. CONCLUSIONS: The results in unselected real-world patients demonstrate a significant geographic difference in malignancy risk in ACS patients, with the highest risk in the north-rural area.

Baseline plasma lipid levels in patients with acute coronary syndrome: Association with 20-year mortality. The ABC-5a* Study on Heart Disease.

BACKGROUND: The relationship between baseline plasma lipid levels during acute coronary syndrome and the outcome has clinical relevance. METHODS: To evaluate their long-term prognostic value, we examined 589 patients admitted with acute coronary syndrome at three hospitals. Baseline plasma lipids were assessed on days 1 and 7. Patients were followed for 20 years or until death. RESULTS: Virtually, all patients completed follow-up; 437 (74%) had died: 24% from coronary artery disease/heart failure (CAD/HF), 21% sudden cardiac death (SCD), 16% from other cardiovascular causes and 39% had non-cardiac death. The incidence rate (IR) of all-cause mortality was not different among patients with baseline plasma lipids less or greater than the median value. The IR of CAD/HF mortality was not significantly higher among patients with greater than median low-density lipoprotein (LDL) cholesterol and triglyceride (TG) levels. The IR of non-cardiac death tended to be lower among patients with greater than median total cholesterol (TC) and LDL levels. Using three levels of adjusted Cox survival models, baseline plasma lipids had no consistent independent or inverse association with all-cause mortality, even after excluding patients who received statins. Competitive risk survival models for each cause of death revealed that the only hazard of non-cardiac death was consistently higher among patients with less than or equal to median TC and LDL levels. CONCLUSION: In the present prospective long-term study, after acute coronary syndrome, baseline plasma lipid levels seem not to be associated with long-term global mortality. Only an independent inverse association between TC and LDL and non-cardiac death has been observed.

Off-label use of Amplatzer Duct Occluder II additional sizes.

OBJECTIVE: To report our experience on novel, off-label use of Amplatzer Duct Occluder type II additional sizes (ADO II-AS) device (St. Jude Medical, Inc.; St. Paul, Minnesota, USA) to manage nonduct shunt lesions. METHODS AND RESULTS: Among the 114 patients submitted to ADO II-AS implantation at our institution, 12 received this device as off-label treatment of paravalvular leak (n = 5), sinus of Valsalva fissuration (n = 2), accessory atrial septal defect (n = 2), muscular ventricular septal defect (n = 1), bleeding bronchial artery aneurysm (n = 1) and reverse shunt due to abnormal origin of left subclavian artery from pulmonary artery (n = 1). Age and body weight of these patients ranged from 3 to 74 years and from 15 to 80 kg, respectively. All procedures were completed without anatomical, functional or ECG complications and without residual shunt. In one patient with mitral paravalvular leak, mild restriction of the posterior disc excursion after device deployment was recorded. CONCLUSION: In our case series, ADO II-AS was well tolerated, versatile and cost-effective in treatment of different types of nonduct shunt lesions, mainly in young children and in older patients with comorbidities.
