  Background: Cardiac myosin binding protein C (cMyC) is a cardiac-specific biomarker that is released after acute ischemic myocardial injury. Cardiac troponins are established cardiac biomarkers of myocardial injury and provide prognostic information in patients with cardiovascular disease (CVD) and in healthy persons from the general population. There is limited data documenting the prognostic value of cMyC in a general population setting. Accordingly, we assessed the prognostic value of cMyC for incident major adverse cardiovascular events (MACE) and mortality in a general population cohort and contrasted these associations with those of cardiac troponins. Methods: We measured cMyC, high-sensitivity cardiac troponin I (hs-cTnI), and high-sensitivity T (hs-cTnT) in serum samples from 3682 community dwellers born in 1950 at the baseline of the Akershus Cardiac Examination 1950 Study obtained from 2012 to 2015. We assessed the associations of all three biomarkers with a composite MACE outcome (nonfatal myocardial infarction, nonfatal ischemic stroke, nonfatal heart failure, myocardial revascularization, or cardiovascular mortality), as well as with all-cause, cardiovascular and non-cardiovascular mortality separately. Results: The median age was 63.9 years and 1885 were male. After a median follow-up of 8.3 years, we recorded 307 composite MACE outcomes and 191 deaths. cMyC was associated with risk of MACE, as was hs-cTnI and hs-cTnT (all P for log-rank test <0.001). cMyC remained independently associated with MACE (hazard ratio per 1 SD in log-transformed biomarker 1.25, 95% CI, 1.14–1.37) and cardiovascular death (hazard ratio 1.41, 95% CI 1.15–1.72) in adjusted analyses and after further adjustment for hs-cTnI or hs-cTnT. Conclusions: cMyC provides strong prognostic information for incident CVD in the general population, independently of that provided by cardiac troponins.

Rationale, design and baseline characteristics of the cardio-oncology registry (CARE) study: a prospective, observational study of cardiotoxic effects during breast cancer therapy.

  Background: Anthracycline and Human Epidermal Growth Factor Receptor 2 (HER2) targeted therapy may induce cancer therapy-related cardiac dysfunction (CTRCD). Current guidelines recommend risk stratification using the Heart Failure Association–International Cardio-Oncology Society (HFA-ICOS) risk assessment tool. However, data on the incidence of CTRCD in contemporary breast cancer populations treated according to current standard-of-care regimens remain limited. Moreover, the actual cardiovascular risk associated with the HFA-ICOS risk categories in breast cancer treatment remains uncertain. Real-world evaluation of whether this consensus-based stratification appropriately separates patients according to subsequent CTRCD risk has been highlighted as a key research priority. Purpose: Overall, the study aims to determine the incidence of CTRCD and to evaluate cardiovascular risk stratification using the HFA-ICOS tool and its association with subsequent CTRCD. Methods: CARE is a prospective observational study including women scheduled for (neo)adjuvant anthracycline therapy and/or HER2-targeted therapy. Echocardiography, using standard and novel echocardiographic parameters, and circulating cardiac biomarkers were assessed at baseline (visit 1), after completion of scheduled therapy (visit 2), and 12 months after completion of scheduled therapy (visit 3). Participants were categorized into three treatment regimen groups: 1) Anthracycline therapy only, 2) HER2-targeted therapy only, and 3) HER2-targeted therapy sequentially to anthracyclines (Figure 1). The primary outcome is incidence of CTRCD. Secondary outcomes include HFA-ICOS risk stratification in relation to subsequent CTRCD. Results: In total, 515 women (median age (Q1,Q3): 53 (45,64) years) were included. Overall, 335 (63%) participants received anthracycline therapy only, 100 (15%) received HER2-targeted therapy only, and 80 (19%) received anthracycline therapy followed by HER2-targeted therapy. Baseline cardiovascular risk factors included hypertension in 20%, current smoking in 13%, diabetes in 7%, and a history of heart disease in 7.6%, while 3.5% had received previous anti-cancer treatment (Table 1). Conclusion: The CARE study is a large prospective observational cardio-oncology study evaluating the incidence of CTRCD after contemporary breast cancer therapy regimens. With systematic echocardiographic and biomarker assessment, the study will provide important insights into the incidence of CTRCD, the performance of the HFA-ICOS risk stratification tool and follow-up strategies in routine cardio-oncology care.Table 1Baseline Characteristics CARE  Figure 1Consort Diagram
