Resting heart rate is an independent predictor of advanced colorectal adenoma recurrence

The utility of resting pulse rate in defining high blood pressure among adolescents in Mbarara municipality, Uganda

High resting pulse rate (RPR) is associated with adverse cardiovascular events and could be used as a marker of cardiovascular health. We determined the correlation between RPR and blood pressure (BP); and its accuracy in defining high blood pressure among adolescents attending secondary schools in Mbarara municipality, south-western Uganda. We conducted a cross-sectional study among secondary school adolescents aged 12-19 years in Mbarara municipality, Uganda. We captured demographic characteristics using a structured questionnaire; and measured anthropometric indices and BP. We performed a linear regression analysis to determine the relationship between RPR and blood pressure and plotted receiver operating characteristics curves (ROC) to assess the accuracy of RPR in defining high BP. We enrolled 616 adolescents with a mean age of 15.6 ± 2.0 years and 65.6% (404/616) were female. The RPR was significantly correlated with diastolic blood pressure (DBP) in both boys (Beta = 0.22 [95% CI: 0.10; 0.36]), p < 0.001 and girls (Beta = 0.51 [95% CI: 0.43; 0.60]), p < 0.001. RPR was significantly correlated with systolic blood pressure (SBP) only in the girls (Beta = 0.23 [95% CI: 0.15; 0.30]), p < 0.001. The optimal threshold for RPR in defining prehypertension was RPR ≥ 76 bpm with an area under the curve (AUC) of 0.653 [95% CI: 0.583-0.722], the sensitivity of 0.737 and specificity of 0.577. In defining hypertension, the optimal threshold was RPR ≥ 79 bpm at a sensitivity of 0.737 and specificity of 0.719, with an AUC of 0.728 [95% CI: 0.624-0.831]. Resting pulse rate was positively correlated with BP and was more accurate in defining hypertension compared to prehypertension in the study.

Initial in-hospital heart rate is associated with long-term survival in patients with acute ischemic stroke

Aims

Increased heart rate has been associated with stroke risk and outcomes. The purpose of this study was to explore the long-term prognostic value of initial in-hospital heart rate in patients with acute ischemic stroke (AIS).

Methods

We analyzed data from 21,655 patients with AIS enrolled (January 2010–September 2018) in the Chang Gung Research Database. Mean initial in-hospital heart rates were averaged and categorized into 10-beat-per-minute (bpm) increments. The primary and secondary outcomes were all-cause mortality and cardiovascular death. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable adjusted Cox proportional hazard models, using the heart rate < 60 bpm subgroup as the reference.

Results

The adjusted HRs for all-cause mortality were 1.23 (95% CI 1.08–1.41) for heart rate 60–69 bpm, 1.74 (95% CI 1.53–1.97) for heart rate 70–79 bpm, 2.16 (95% CI 1.89–2.46) for heart rate 80–89 bpm, and 2.83 (95% CI 2.46–3.25) for heart rate ≥ 90 bpm compared with the reference group. Likewise, heart rate ≥ 60 bpm was also associated with an increased risk of cardiovascular death (adjusted HR 1.18 [95% CI 0.95–1.46] for heart rate 60–69 bpm, 1.57 [95% CI 1.28–1.93] for heart rate 70–79 bpm, 1.98 [95% CI 1.60–2.45] for heart rate 80–89 bpm, and 2.36 [95% CI 1.89–2.95] for heart rate ≥ 90 bpm).

Conclusions

High initial in-hospital heart rate is an independent predictor of all-cause mortality and cardiovascular death in patients with AIS.

Resting heart rate is associated with colorectal advanced adenoma

Background and aims

Resting heart rate is an independent predictor of colorectal cancer (CRC) development and CRC-related mortality. However, little is known about the relationship between resting heart rate and colorectal adenoma development. We aimed to investigate this association in a population who underwent screening colonoscopy.

Methods

Among 39,021 patients who underwent both electrocardiogram and screening colonoscopy during routine health examinations at the Seoul National University Bundang Hospital, Health Promotion Center, Korea from January 2014 to July 2019, 1,344 patients had advanced adenoma. We performed 1:1 propensity score (PS) matching to establish a control group that mitigated the confounding effects of age and sex. We performed multivariate logistic regression analyses to identify the independent risk factors of advanced adenoma development.

Results

Resting heart rate was significantly higher in the advanced adenoma group than in the control group. The prevalence of advanced polyp increased across the quartiles of resting heart rate. Patients with higher resting heart rates were more likely to be older, smokers, and have increased blood pressure and DM and less likely to engage in active exercises than those with lower resting heart rates. Patients with higher resting heart rates had higher serum glucose, triglyceride, hemoglobin A1C, and insulin levels and lower high-density lipoprotein cholesterol levels. Patients with resting heart rate in the highest quartile (≥71 bpm) still showed significantly increased odds ratio (OR) of advanced adenoma development (OR: 1.379, 95% confidence interval: 1.099–1.731, p = 0.006).

Conclusions

High resting heart rate was a meaningful independent risk factor of advanced adenoma development.

[Tumor effects on the heart and circulation]

As a result of the continuous development of modern cancer treatment, more cancer patients can be cured every year. However, since many patients experience cardiovascular problems before, during and after their cancer treatment, cardio-oncology is becoming increasingly important. Numerous therapies can cause cardiotoxicity, such as chemotherapy, immunotherapy, antibody therapy and radiotherapy. If these remain undetected, the patient may develop, e.g. heart failure or severe heart valve damage. The broad spectrum of cardiovascular comorbidities has become an immense challenge for cardiologists and oncologists. Cardio-oncology also deals with the effects that cancer has on the cardiovascular system. New research indicates that the tumor itself also has direct negative effects on the heart, mediated by messenger substances. Therefore, it is important to understand which cancer patients are at increased cardiovascular risk, thereby enabling the development of new therapeutic approaches in the long term to maintain mobility and improve patient prognosis.

Risk Factors for Recurrent Colorectal Polyps

The recurrence of colorectal polyps is caused by various factors and leads to the carcinogenesis of colorectal cancer, which ranks third in incidence and fourth in mortality among cancers worldwide. The potential risk factors for colorectal polyp recurrence have been demonstrated in multiple trials. However, an article that pools and summarizes the various results is needed. This review enumerates and analyzes some risk factors in terms of patient characteristics, procedural operations, polyp characteristics, and dietary aspects to propose some effective prophylactic measures. This review aimed to provide a reference for clinical application and guide patients to prevent colorectal polyp recurrence in a more effective manner.

Speckle-Tracking Echocardiography for Cardioncological Evaluation in Bevacizumab-Treated Colorectal Cancer Patients

Angiogenesis inhibitor Bevacizumab (BVZ) may lead to the development of adverse effects, including hypertension and cardiac ischemia. Whether assessment of changes in myocardial strain by two-dimensional speckle-tracking echocardiography (2D-STE) can be of value in detecting BVZ-mediated cardiotoxicity at an earlier stage is not known. We investigated whether 2D-STE can non-invasively detect early evidence of cardiotoxicity in metastatic colorectal cancer (mCRC) patients treated with BVZ. Between January and June 2019, 25 consecutive patients (71.8 ± 7.5 year/old, 17 males) with mCRC were prospectively enrolled. Patients underwent physical examination, blood tests, and conventional 2D-transthoracic echocardiography implemented with 2D-STE analysis, at baseline and at 3 and 6 months following treatment with BVZ (15 mg/kg every 15 days) + 5-fluorouracil/folinic acid plus oxaliplatin (FOLFOX i.v.). At 6-month follow-up, we assessed occurrence of global longitudinal strain (GLS) impairment (> 15% decrease in GLS compared with baseline) as primary end-point and a new-onset systemic hypertension (secondary end-point). On average, GLS showed a progressive significant impairment after BVZ, from - 17.4 ± 3.2% at baseline to - 16 ± 2.9% (p = 0.003) at 6-month follow-up; > 15% decrease in GLS (primary end-point) was detected in 9 patients (36%). All other strain parameters remained unchanged. New-onset systemic hypertension (secondary end-point) was diagnosed in five patients (20%). No significant changes were observed in serial high-sensitivity cardiac troponin I measurements. No patient developed significant changes in LV size or LV ejection fraction; no case of clinically symptomatic HF was observed during BVZ-treatment. Measurement of GLS by 2D-STE analysis can effectively detect BVZ-mediated cardiotoxicity at an early stage.

Oncology and Cardiac Rehabilitation: An Underrated Relationship

Cancer and cardiovascular diseases are globally the leading causes of mortality and morbidity. These conditions are closely related, beyond that of sharing many risk factors. The term bidirectional relationship indicates that cardiovascular diseases increase the likelihood of getting cancer and vice versa. The biological and biochemical pathways underlying this close relationship will be analyzed. In this new overlapping scenario, physical activity and exercise are proven protective behaviors against both cardiovascular diseases and cancer. Many observational studies link an increase in physical activity to a reduction in either the development or progression of cancer, as well as to a reduction in risk in cardiovascular diseases, a non-negligible cause of death for long-term cancer survivors. Exercise is an effective tool for improving cardio-respiratory fitness, quality of life, psychological wellbeing, reducing fatigue, anxiety and depression. Finally, it can counteract the toxic effects of cancer therapy. The protection obtained from physical activity and exercise will be discussed in the various stages of the cancer continuum, from diagnosis, to adjuvant therapy, and from the metastatic phase to long-term effects. Particular attention will be paid to the shelter against chemotherapy, radiotherapy, cardiovascular risk factors or new onset cardiovascular diseases. Cardio-Oncology Rehabilitation is an exercise-based multi-component intervention, starting from the model of Cardiac Rehabilitation, with few modifications, to improve care and the prognosis of a patient's cancer. The network of professionals dedicated to Cardiac Rehabilitation is a ready-to-use resource, for implementing Cardio-Oncology Rehabilitation.

Greater Well-Being in More Physically Active Cancer Patients Who Are Enrolled in Supportive Care Services

Background: Cancers are one of the leading causes of mortality worldwide. Cancer patients are increasingly seeking integrative care clinics to promote their health and well-being during and after treatment. Aim: To examine relationships between physical activity (PA) and quality of life (QoL) in a sample of cancer patients enrolling in integrative care in a supportive care clinic. Also, to explore circulating inflammatory biomarkers and heart rate variability (HRV) in relationship to PA and QoL. Methods: A cross-sectional design of adult patients who sought care in the InspireHealth clinic, Vancouver, British Columbia, Canada. Patients with complete PA data (n = 118) answered psychosocial questionnaires, provided blood samples, and received HRV recordings before enrollment. Patients were stratified into “less” versus “more” active groups according to PA guidelines (150 minutes of moderate or 75 minutes of vigorous PA or an equivalent combination). Results: Breast (33.1%) and prostate (10.2%) cancers were the most prevalent primary diagnoses. Patients engaging in more PA reported better physical (U = 1265.5, P = .013), functional (U = 1306.5, P = .024), and general QoL (U = 1341, P = .039), less fatigue (U = 1268, P = .014), fewer physical cancer-related symptoms (U = 2.338, P = .021), and less general distress (U = 2.061, P = .021). Between PA groups, type of primary cancer diagnosis differed (χ² = 41.79, P = .014), while stages of cancer did not (χ² = 3.95, P = .412). Fewer patients reported depressed mood within the more active group (χ² = 6.131, P = .047). More active patients were also less likely to have ever used tobacco (χ² = 7.41, P = .025) and used fewer nutritional supplements (χ² = 39.74, P ≤ .001). An inflammatory biomarker index was negatively correlated with vigorous PA (r_s = −0.215, P = .022). Multivariable linear regression (R² = 0.71) revealed that age (β = 0.22; P = .001), fatigue (β = −0.43; P ≤ .001), anxiety (β = −0.14; P = .048), and social support (β = 0.38; P = .001) were significant correlates of QoL.

Increased resting heart rate and prognosis in treatment-naïve unselected cancer patients: results from a prospective observational study

Aims

Cancer patients suffer from impaired cardiovascular function. Elevated resting heart rate (RHR) has been identified as a marker for increased long‐term mortality in cancer patients prior to the receipt of anticancer treatment. We aimed to establish whether RHR is associated with survival in treatment‐naïve cancer patients.

Methods and results

This prospective study enrolled 548 unselected treatment‐naïve cancer patients between 2011 and 2013. The median age of the cohort was 62 years; 40.9% were male and 32.7% had metastatic disease. Median RHR was 72 b.p.m. Most patients were in sinus rhythm (n = 507, 92.5%). Clinical heart failure was noted in 37 (6.8%) patients. RHR was not related to cancer stage (P = 0.504). Patients in the highest RHR tertile had higher levels of high‐sensitivity troponin (P = 0.003) and N‐terminal pro‐B‐type natriuretic peptide (P = 0.039). During a median follow‐up of 25 months (interquartile range: 16–32 months; range: 0–40 months), 185 (33.8%) patients died from any cause [1‐year‐mortality: 17%, 95% confidence interval (CI) 13–20%]. In univariate survival analysis, RHR predicted all‐cause mortality [crude hazard ratio (HR) for a 5 b.p.m. increase in RHR: 1.09, 95% CI 1.04–1.15; P < 0.001], and remained significantly associated with outcome after adjustment for age, gender, tumour entity, tumour stage, cardiac status and haemoglobin (adjusted HR for a 5 b.p.m. increase in RHR: 1.10, 95% CI 1.04–1.16; P < 0.001). There was no significant impact of metastatic/non‐metastatic disease state on the predictive value of RHR (P = 0.433 for interaction). In subgroup analyses, the strongest associations for RHR with mortality were observed in lung (crude HR 1.14; P = 0.007) and gastrointestinal (crude HR 1.31; P < 0.001) cancer.

Conclusions

Treatment‐naïve cancer patients with higher RHRs display higher levels of cardiovascular biomarkers. RHR was independently associated with all‐cause mortality, especially in lung and gastrointestinal cancers. Elevated RHR and cardiovascular biomarkers may represent early signs of incipient cardiac dysfunction.

Recent advances in cardio-oncology: a report from the 'Heart Failure Association 2019 and World Congress on Acute Heart Failure 2019'

While anti-cancer therapies, including chemotherapy, immunotherapy, radiotherapy, and targeted therapy, are constantly advancing, cardiovascular toxicity has become a major challenge for cardiologists and oncologists. This has led to an increasing demand of cardio-oncology units in Europe and a growing interest of clinicians and researchers. The Heart Failure 2019 meeting of the Heart Failure Association of the European Society of Cardiology in Athens has therefore created a scientific programme that included four dedicated sessions on the topic along with several additional lectures. The major points that were discussed at the congress included the implementation and delivery of a cardio-oncology service, the collaboration among cardio-oncology experts, and the risk stratification, prevention, and early recognition of cardiotoxicity. Furthermore, sessions addressed the numerous different anti-cancer therapies associated with cardiotoxic effects and provided guidance on how to treat cancer patients who develop cardiovascular disease before, during, and after treatment.

Association between Resting Heart Rate and Colorectal Cancer: Results from a Case-Controlled Study

Previous studies evaluating associations between resting heart rate (RHR) and cancer-related mortality/prognosis have yielded conflicting results. We investigated whether elevations in RHR are associated with colorectal cancer (CRC). We conducted a case-controlled study involving 1241 CRC patients and 5909 cancer-free controls from the Korean National Health and Nutrition Examination Survey. After propensity score (PS) matching, 1207 CRC patients and 1207 matched controls were analyzed. Associations between RHR and CRC, colon, and rectal cancer were analyzed in appropriate patient subgroups using multiple and conditional logistic regression. Receiver operating characteristics analysis yielded the optimal RHR cut-point to predict CRC. RHR was significantly higher in CRC, colon, and rectal cancer patients than in controls (72.7 bpm in CRC, 72.8 bpm in colon cancer, 72.3 bpm in rectal cancer, and 68.7 bpm in controls; all p < 0.001). Analysis of data prior to PS matching yielded the following odds ratios (ORs) per RHR increment for CRC, colon, and rectal cancer: 1.043 (95% confidence intervals (CIs): 1.036–1.049), 1.045 (95% CI: 1.037–1.053), and 1.040 (95% CI: 1.030–1.051), respectively, in unadjusted models, and 1.043 (95% CI: 1.034–1.051), 1.046 (95% CI: 1.037–1.055), and 1.040 (95% CI: 1.027–1.052), respectively, in multivariable adjusted models. Patients with CRC, colon, and rectal cancer have a significantly higher RHR compared to cancer-free controls.

Relationship between resting heart rate and metabolic risk factors in breast cancer patients

BACKGROUND

Higher resting heart rate (RHR) was associated with poor prognosis in breast cancer survivors, but the mechanism underlying such association has not been fully studied. We investigated the association between RHR and metabolic risk factors in stage I-III breast cancer survivors.

METHODS

Among 11,013 women diagnosed with breast cancer between 2005 and 2013 at the Severance hospital in Seoul, Korea, a total of 4980 patients met our inclusion criteria for the final analysis. Multivariable linear regressions were used to examine the association between RHR and metabolic risk factors, including systolic blood pressure (SBP), diastolic blood pressure (DBP), glucose, triglyceride (TG), total cholesterol, high density lipid cholesterol (HDLC), and low density lipid cholesterol.

RESULTS

The results showed that RHR had significant linear associations with SBP (p = .02), DBP (p < .001), TG (p < .001), glucose (p < .001), and HDL-C (p < .001). Compared to participants in the lowest quintile of RHR (<68 beat per min (bpm)), participants in the highest quintile (≥85 bpm) had higher DBP by 4 mmHg, TG by 13 mg/dl, and glucose by 5 mg/dl after adjusting for potential confounders. Further subgroup analyses showed that the association of RHR may differ by age and menopausal status for fasting glucose and cancer stage, chemotherapy, estrogen and progesterone receptor status for TG.

CONCLUSIONS

We observed a strong positive association of RHR with fasting glucose, TG, and DBP in breast cancer survivors, which may potentially explain the association between RHR and breast cancer prognosis.
