Abstract

Aim To investigate the clinical features and incidence ofmalignant neoplasia during 17 years of follow-up in anunselected sample of patients with acute coronarysyndrome (ACS).

Methods The Adria, Bassano, Conegliano, and PadovaHospital-4 Study on Heart Disease is an ongoing,prospective study of an unbiased population of patientswith ACS. Baseline clinical and laboratory data wereobtained during the first 7 days of hospitalization at threedifferent 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 developedmalignant neoplastic disease. The incidence rate was 17.8cases per 1000 person-years, which was about three timeshigher than that observed in the general population.Patients had a shorter duration of neoplasia when theydeveloped it after enrollment compared with those withpreexisting neoplasia [hazard ratioU2.0 (1.5–2.6),PU0.001]. Patients with neoplasia who died during follow-up had an earlier onset of neoplasia [hazard ratioU1.8(1.1–2.9),PU0.01] and shorter duration than survivors[hazard ratioU4.1 (2.4–7.0),P<0.0001]. The estimated time to diagnosis of neoplasia indicated elderly patientshad a significantly higher risk than younger people duringthe 17 years of follow-up. After the onset of neoplasia,survival time declined more sharply in the elderly thanyounger people.

Conclusion The long-term prospective study showed thatpatients with ACS have a higher incidence of malignancythan the general population. Those who develop neoplasmafter being diagnosed with ACS have a worse prognosisthan patients with a preexisting neoplasia.

Welcome

In 1992, a small group of medical researchers and other participants embarked on an project to investigate new clinical factors for heart disease, studying patients with acute coronary syndrome and following them for many years. Today, the observations on the long-term survival after acute coronary syndrome are internationally acknowledged. Main results appears on the most important cardiovascular texts across the world. The study is called “the ABC heart disease study”.

Nel 1992, un piccolo gruppo di medici ricercatori ed altri operatori sanitari, iniziarono un progetto per studiare nuovi fattori clinici della malattia cardiaca, studiando pazienti con sindrome coronarica acuta e seguendoli per molti anni. Oggi, ciò che è stato osservato sulla sopravvivenza a lungo temine dopo sindrome coronarica acuta è riconosciuto a livello internazionale. I principali risultati appaiono sui maggiori testi di medicina cardiovascolare in tutto il mondo. Questo progetto è stato chiamato “the ABC heart disease study”.

Mission

The Mission of the ABC Study on Heart Disease Project is to promote the knowledge on heart disease chiefly based on the long-term follow up of the patients. And to promote citizen health supporting preventive, social, and sport activities.
