Insights

Cancer survivors often have poor cardiovascular health (CVH), increasing mortality risk. Improving CVH through lifestyle changes and education is crucial for this population.

Area of Science:

  • Cardiovascular disease (CVD) research
  • Cancer survivorship studies
  • Public health and preventative medicine

Background:

  • Cardiovascular disease (CVD) is a leading cause of death in cancer survivors, with lifestyle factors impacting both cancer and cardiovascular mortality.
  • Cardiovascular health (CVH), defined by metrics like Life's Simple 7 (LS7) or Life's Essential 8 (LE8), is understudied in cancer survivors despite its association with cancer mortality.
  • Less than ideal CVH is linked to increased cancer mortality, highlighting a critical need for research in this area.

Approach:

  • A systematic review was conducted following PRISMA guidelines, searching major databases (PubMed, Scopus, CINAHL, Embase) for studies on cancer survivors and cardiovascular health.
  • Keywords included "cancer survivors", "cancer patient", "cardiovascular health", and "cardiovascular risk factors", with articles assessed for risk of bias and synthesized.
  • Ten studies met inclusion criteria, utilizing LS7 or LE8 metrics to assess CVH in a population of 35,980 cancer survivors (ages 40-70).

Key Points:

  • The review identified four emergent themes: CVH outcomes in cancer survivors, social determinants influencing CVH, associations between CVH and other health outcomes, and opportunities for CVH awareness.
  • The majority of included studies focused on survivors of breast, gynecological, endometrial, prostate, colon, lung, lymphoma, and skin cancers.
  • The analyzed population (n=35,980) comprised mostly female, non-Black individuals with an average survivorship of 7.2 years.

Conclusions:

  • Cancer survivors frequently exhibit less than ideal cardiovascular health outcomes.
  • Interventions focused on education and empowerment are recommended to support lifestyle modifications that can improve CVH in cancer survivors.
  • Addressing CVH in cancer survivorship is essential for reducing overall mortality and improving long-term health trajectories.

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
