Association between plasma lipid levels during acute coronary syndrome and long-term malignancy risk. The ABC-4* study on heart disease.

BACKGROUND: Emerging evidence suggests that patients with coronary artery disease carry an increased risk of developing malignancy, with deleterious effects on long-term prognosis. Our aim was to ascertain whether baseline plasma lipid levels during acute coronary syndrome (ACS) are associated with malignancy in long-term. METHODS: This study included 589 patients admitted with ACS to three centers and discharged alive. Plasma lipid levels were assessed on the first morning after admission. Patients were followed for 17 years or until death. RESULTS: Five hundred seventy-one patients were free from malignancy at enrollment, of them 99 (17.3%) developed the disease during follow-up and 75 (13.1%) died due to it. Compared to patients without malignancy, those with malignancy showed lower plasma levels of total cholesterol (TC), low-density lipoprotein (LDL), and triglycerides (TG). The groups showed similar statin use rates at any time in follow-up. The incidence rate of neoplasia and neoplastic mortality was higher in patients with baseline TC or LDL values ≤ median; they showed 85 and 72% increased incidence rate of developing malignancy and 133 and 122% increased incidence rate of neoplastic death respectively. No differences were observed relative to HDL and TG levels. In survival analysis using Cox regression with parsimonious models, patients with baseline TC or LDL values > median, respectively, showed risks of 0.6(95% CI 0.4-0.9; p = 0.01) and 0.6(95%CI 0.4-0.9; p = 0.02) for malignancy onset, and 0.5(95% CI 0.3-0.8; p = 0.005) and 0.5(95% CI 0.3-0.8; p = 0.004) for neoplastic death. Similar results were obtained using competitive risk analysis with parsimonious models. CONCLUSIONS: This long-term prospective study of an unselected real-world patient sample showed that neoplasia onset and mortality are independently associated with low plasma TC and LDL levels at admission for ACS.

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.

Neoplastic disease after acute coronary syndrome: incidence, duration, and features: the ABC-4* Study on Heart Disease.

AIM: To investigate the clinical features and incidence of malignant neoplasia during 17 years of follow-up in an unselected sample of patients with acute coronary syndrome (ACS). METHODS: The Adria, Bassano, Conegliano, and Padova Hospital-4 Study on Heart Disease is an ongoing, prospective study of an unbiased population of patients with ACS. Baseline clinical and laboratory data were obtained during the first 7 days of hospitalization at three different intensive coronary care units. The current study included data from 589 patients with ACS. RESULTS: At enrollment, 19 patients had confirmed neoplasia. During follow-up, 99 additional patients developed malignant neoplastic disease. The incidence rate was 17.8 cases per 1000 person-years, which was about three times higher than that observed in the general population. Patients had a shorter duration of neoplasia when they developed it after enrollment compared with those with preexisting neoplasia [hazard ratio = 2.0 (1.5-2.6), P = 0.001]. Patients with neoplasia who died during follow-up had an earlier onset of neoplasia [hazard ratio = 1.8 (1.1-2.9), P = 0.01] and shorter duration than survivors [hazard ratio = 4.1 (2.4-7.0), P < 0.0001]. The estimated time to diagnosis of neoplasia indicated elderly patients had a significantly higher risk than younger people during the 17 years of follow-up. After the onset of neoplasia, survival time declined more sharply in the elderly than younger people. CONCLUSION: The long-term prospective study showed that patients with ACS have a higher incidence of malignancy than the general population. Those who develop neoplasm after being diagnosed with ACS have a worse prognosis than patients with a preexisting neoplasia.

Heart failure in women and men during acute coronary syndrome and long-term cardiovascular mortality (the ABC-3* Study on Heart Disease) (*Adria, Bassano, Conegliano, and Padova Hospitals).

AIMS: We investigated the gender-based differences in the association between heart failure (HF) during acute coronary syndrome (ACS) and post-discharge, long-term cardiovascular (CV) mortality. METHODS AND RESULTS: The present study included 557 patients enrolled in three intensive coronary care units and discharged alive. HF during ACS was evaluated by Killip class and left ventricular ejection fraction (LVEF). Interaction between gender and HF after 15years of follow up was studied using Cox models including a formal interaction term. Median age was 67 (interquartile range [IQR], 59-75) years, 29% were females, 37% had non-ST elevation myocardial infarction and 32% Killip class>1, and median LVEF was 53% (IQR 46-61). All but five patients were followed up to 15years, representing 5332 person-years. Of these, 40.2% died of CV-related causes. Crude CV mortality rate was higher among women (52.2%) than men (35.3%; P<0.0001). At a univariable level, a negative interaction between female gender and Killip class for CV mortality was found [hazard ratio (HR)=0.51 (0.34-0.77), P=0.002]. In five multivariable models after controlling for age, main CV risk factors, clinical features, post-discharge medical treatment, and mechanical coronary reperfusion, the interaction was significant across all models [HR=0.63 (0.42-0.95), P=0.02 in the fully adjusted model]. LVEF showed no significant hazard associated with female gender on univariable analysis [HR=1.4 (0.9-0.2.0), P=0.11] but did so in all adjusted models [HR=1.7 (1.2-2.5), P=0.005 in the fully adjusted model]. CONCLUSION: Gender is a consistent, independent effect modifier in the association between HF and long-term CV mortality after ACS.

Gender differences and role of pregnancy in the history of post-surgical women affected by tetralogy of Fallot.

BACKGROUND: The aim of this study was to describe gender differences in patients operated on for TOF and to define the impact of pregnancy in late post-surgical follow-up in women. METHODS: In this research, we studied 145 patients after correction of TOF: 66 male, 79 women, 41 of which reported history of 68 pregnancies, means age 37±10 years, age at operation 7±8 years, mean duration of post-surgical follow-up 30±7 years. Selected variables were compared according to sex and according to history of pregnancy with statistical tests. RESULTS: Men had more severe hemodynamic impairment and a higher number of cardiac reoperations than females. 41% of patients had at least one complication during pregnancy; there were 16 (67%) abortions and 39 (74%) Caesarian delivers; the recurrence of congenital heart defect was 10%. After pregnancy, there was a shift from first to second functional class: unique pregnancy determined no differences in term of morpho-functional ventricular features compared to nulliparous, but they complained fatigue and palpitation and echocardiographyc dysfunction. Left ventricular dysfunction and QRS duration at ECG were independent predictors of ventricular arrhythmias in all patients. CONCLUSIONS: There were no gender-specific differences in patients operated on for TOF using ventriculotomy. Pregnancy is an event in these patients at risk for the newborn, in terms of miscarriage, prematurity, and recurrence of birth defects, and for the mother in terms of ventricular dysfunction and electrical instability. At least a single pregnancy does not appear to significantly modify the natural history of post-surgical patients operated on for TOF.

A new view on congenital heart disease: clinical burden prevision of changing patients.

The introduction and diffusion of cross-sectional echocardiography at the end of 1970s significantly improved case ascertainment and allowed the identification of congenital heart defects with a significant increase of mild forms. However, the prevalence of severe congenital heart disease (CHD), which represented 11.7% of overall cardiovascular malformations, remained quite stable (less than 1 per 1000 live births). In past decades, a new population of adults with CHD emerged who need specialized care in centres with trained and experienced professional staff with a different level of expertise. Clinical implications of this new scenario are discussed in this article.

Woman, 70 years of age, affected by ALCAPA without surgical repair.

Few cases of anomalous origin of the left coronary artery from the pulmonary artery remain asymptomatic until adolescence, and it is very rare to find a patient with this disease reaching the age of 70 without having undergone any surgery. Up to now, there have been only three other cases of patients, more than 70 years of age, with this congenital heart effect described in medical literature. We report the clinical history and the cardiac morphofunctional findings of 12 years of follow-up after a very late diagnosis of anomalous origin of the left coronary artery from the pulmonary artery.

Electrocardiographic criteria of left ventricular hypertrophy in general population.

The question on whether the electrocardiographic criteria are reliable for detection of left ventricular hypertrophy (LVH) and play a role in predicting outcome is open. Answer can only proceed from population-based studies over unselected people followed up for years. In this study, 1,699 subjects from general population underwent echocardiogram and standard electrocardiogram (ECG) codified for LVH with Minnesota code and with other five methods. Other items were also recorded and used as covariables. Left ventricular mass index (LVMI) was 127.6 +/- 44.9 g m(-2) in men and 120.8 +/- 41.2 g m(-2 )in women, and correlated directly with age in both genders. Prevalence of echocardiographic LVH was 36.6% in men and 53.4% in women. LVMI correlated directly with the Sokolow-Lyon score in both genders at any age, with the Romhilt-Estes, Cornell and R(aVL) scores in all subjects but elderly men, and with the Lewis score in men and women aged < or =69 years. Sensitivity and the predictive value of electrocardiographic tests, as well as the prevalence of LVH diagnosed with electrocardiographic criteria, were always low. Specificity was high for all the tests, and in particular for the Cornell index. Only when diagnosed with echocardiogram or with the Sokolow-Lyon criterion, LVH was an independent predictor of mortality. We conclude that electrocardiographic tests cannot be used as a surrogate of echocardiogram in detecting LVH in the general population because their positive predictive value (PPV) is unacceptably low. On the contrary, they could replace echocardiography in the follow up and for prediction of outcome, when LVH has previously been correctly diagnosed with other methods.
