Brief Summary

This study will prospectively monitor cancer patients receiving chemotherapy (including molecular targeted therapies) for cardiovascular adverse events using biomarkers and imaging. The goal is to develop a predictive model for major adverse cardiovascular events (MACE) in this population by integrating both local factors (e.g. central venous catheter-related thrombosis) and systemic factors (e.g. age, comorbidities, genetic predisposition). An active surveillance system employing periodic cardiac evaluations (ECG, echocardiography) and biomarker measurements (troponin T, NT-proBNP) will enable early detection of cardiotoxic effects. The impact of these adverse events and the monitoring strategy on patients' quality of life will also be assessed.

Detailed Description

Cancer patients are at heightened risk of cardiovascular complications due to both their disease and its treatments. Many chemotherapeutic and targeted agents (e.g. anthracyclines, trastuzumab, bevacizumab, tyrosine kinase inhibitors) carry cardiotoxic potential, leading to diverse manifestations of MACE such as heart failure, arrhythmias, ischemic heart disease, valvular dysfunction, hypertension, thromboembolism, and others. As cancer survival improves and newer therapies are widely used, the incidence of treatment-related cardiac toxicity continues to rise. Early cardiotoxic changes are often subclinical, making proactive monitoring essential. Research has shown that cardiac biomarkers can rise before left ventricular ejection fraction declines, enabling "pre-symptomatic" detection of cardiotoxicity. By quantitatively analyzing the predictive value of each indicator for MACE, the study aims to construct a comprehensive risk prediction model for precise cardiovascular risk evaluation in cancer patients. Both local risk factors (e.g., indwelling catheter-related thrombosis) and systemic factors (e.g., age, hypercoagulability, body mass index) will be incorporated, reflecting the interplay of factors contributing to MACE. Genetic biomarkers will also be explored: blood samples are collected for genomic analysis (such as SNP genotyping and whole genome sequencing) to identify genetic polymorphisms associated with increased susceptibility to therapy-related MACE. By comparing patients who develop cardiovascular events to those who do not, we will characterize the incidence, timing, affected organs, and clinical presentation of MACE in cancer patients. Patient-reported quality of life will be evaluated using validated questionnaires, to determine how the occurrence of adverse cardiovascular events (and the implementation of active monitoring) affects daily functioning and overall well-being. Ultimately, this study's findings will provide a scientific basis for individualized risk stratification and preventive interventions in cardio-oncology, supporting optimized clinical strategies to mitigate cardiovascular risk without compromising effective cancer treatment.

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Study Groups

Group 1: Patients with Cardiovascular Adverse Events (MACE Group).

Participants who experience one or more major adverse cardiovascular events during the study period. This case group will consist of all patients in the cohort who develop a new cardiovascular event (e.g., heart failure, arrhythmia, myocardial ischemia, thromboembolism, etc.) while undergoing chemotherapy or by the end of follow-up.

No interventions assigned to this group

Group 2: Patients without Cardiovascular Adverse Events (No MACE Group).

Participants who do not experience any major cardiovascular adverse event during the study period. This control cohort includes patients from the same population (cancer patients on chemo/targeted therapy) who complete their treatment and follow-up without incident MACE. These patients will be frequency-matched by general characteristics such as age and sex to the MACE group for comparisons (all are adult Chinese patients with malignancy, no history of prior thrombotic events).

No interventions assigned to this group
