Background

Atrial fibrillation (AF) has been associated with thoracic radiotherapy, but the specific risk with irradiating different cardiac substructures remains unknown.

Objectives

This study sought to examine the relationship between irradiation of cardiac substructures and the risk of clinically significant (grade ≥3) AF.

Methods

We analyzed data from patients who underwent definitive radiotherapy for localized cancers (non–small cell lung, breast, Hodgkin lymphoma, or esophageal) at our institution between 2004 and 2022. The 2-Gy fraction equivalent dose was calculated for cardiac substructures, including the pulmonary veins (PVs), left atrium, sinoatrial node, and left coronary arteries (the left main, left anterior descending, and left circumflex arteries). Competing risk models (subdistribution HRs [sHRs]) for AF incidence were adjusted for the Mayo AF risk score (MAFRS).

Results

Among 539 patients, the median follow-up was 58.8 months. The 5-year cumulative incidence of AF was 11.1% for non–small cell lung cancer, 8.3% for esophageal cancer, 1.3% for breast cancer, and 0.8% for Hodgkin lymphoma. Increased AF risk was associated with a higher PV maximum dose (dmax) (sHR: 1.22; P < 0.001), larger left atrial volume (sHR: 1.01; P = 0.002), greater smoking history in pack-years (sHR: 1.01; P = 0.010), and higher MAFRS (sHR: 1.16; P < 0.001). PV dmax remained a significant predictor of AF across different MAFRS subgroups (Pinteraction = 0.11), and a PV dmax >39.7 Gy was linked to a higher AF risk, even when stratified by MAFRS.

Conclusions

PV dmax is a significant predictor of grade ≥3 AF regardless of underlying risk factors. These findings highlight the importance of cardiac substructures in radiation toxicity and suggest that various PV dose metrics should be further validated in clinical settings.
背景:心房颤动(AF)与胸部放射治疗有关,但照射不同心脏亚结构的具体风险尚不清楚。目的:本研究旨在探讨心脏亚结构照射与临床显著性(≥3级)af风险之间的关系。方法:我们分析了2004年至2022年在我们机构接受局限性癌症(非小细胞肺癌、乳腺癌、霍奇金淋巴瘤或食管癌)明确放疗的患者的数据。计算心脏亚结构,包括肺静脉(pv)、左心房、窦房结和左冠状动脉(左主干、左前降支和左旋支)的2 gy分数等效剂量。根据Mayo房颤风险评分(MAFRS)对房颤发生率的竞争风险模型(亚分布hr [sHRs])进行调整。结果:539例患者中位随访时间为58.8个月。非小细胞肺癌的5年累积发病率为11.1%,食管癌为8.3%,乳腺癌为1.3%,霍奇金淋巴瘤为0.8%。增加的房颤风险与较高的PV最大剂量(dmax)相关(sHR: 1.22;P 0.001),左房容积增大(sHR: 1.01;P = 0.002),吸烟史以包年计(sHR: 1.01;P = 0.010),较高的MAFRS (sHR: 1.16;P 0.001)。PV dmax仍然是不同MAFRS亚组中AF的重要预测因子(P交互作用= 0.11),PV dmax bb0 39.7 Gy与较高的AF风险相关,即使按MAFRS分层也是如此。结论:无论潜在的危险因素如何,PV - dmax是≥3级房颤的重要预测因子。这些发现强调了心脏亚结构在辐射毒性中的重要性,并建议在临床环境中进一步验证各种PV剂量指标。

Cardiovascular disease is common in patients with prostate cancer and is a significant cause of death. Cardiovascular risk factors are frequent in this population and are often not addressed to thresholds recommended by cardiovascular practice guidelines. Androgen deprivation therapy reduces muscle strength and increases adiposity, increasing the risk for diabetes and hypertension, although its relationship with adverse cardiovascular events requires confirmation. Androgen receptor pathway inhibitors, including androgen receptor antagonists and cytochrome P450 17A1 inhibitors confer incremental risks for hypertension and cardiovascular events to androgen deprivation therapy. Lower cardiovascular risk with gonadotropin-releasing hormone antagonists compared with agonists requires confirmation in well-designed randomized trials.
心血管疾病在前列腺癌患者中很常见,是导致死亡的重要原因。心血管危险因素在这一人群中很常见,而且往往没有达到心血管实践指南推荐的阈值。雄激素剥夺疗法降低肌肉力量,增加肥胖,增加糖尿病和高血压的风险,尽管其与不良心血管事件的关系有待证实。雄激素受体途径抑制剂,包括雄激素受体拮抗剂和细胞色素P450 17A1抑制剂,使雄激素剥夺治疗增加高血压和心血管事件的风险。与激动剂相比,促性腺激素释放激素拮抗剂降低心血管风险需要精心设计的随机试验来证实。

Background

Cancer survivors face an elevated risk of cardiovascular disease, with physical inactivity after cancer treatment potentially worsening this risk.

Objectives

The aim of this study was to investigate the association between physical activity before and after a cancer diagnosis and the risk for heart disease.

Methods

A nationwide cohort of 269,943 cancer survivors (mean age 56.3, 45.7% men) was evaluated for physical activity adherence 2 years before and after diagnosis. The primary outcomes were the incidence of myocardial infarction (MI), heart failure (HF), and atrial fibrillation. Subdistribution HRs (sHRs) and 95% CIs were calculated using Gray’s method, accounting for death as a competing risk.

Results

Over a follow-up period of 1,111,329.28 person-years, compared with those who remained inactive, persistent physical activity was associated with a 20% reduction in MI risk (sHR: 0.80; 95% CI: 0.70-0.91) and a 16% reduction risk in HF risk (sHR: 0.84; 95% CI: 0.78-0.90). Initiating physical activity after a cancer diagnosis was linked to an 11% lower risk for MI (sHR: 0.89; 95% CI: 0.79-0.99) and a 13% lower risk for HF (sHR: 0.87; 95% CI: 0.82-0.93). Being active only before diagnosis was associated with a 20% lower risk for MI (sHR: 0.80; 95% CI: 0.71-0.91) and a 6% lower risk for HF (sHR: 0.94; 95% CI: 0.88-1.00). No association was observed between physical activity and atrial fibrillation risk. Associations varied by primary cancer site.

Conclusions

These findings underscore the importance of maintaining physical activity for cardiovascular health in cancer survivors and suggest that physical activity before a diagnosis may offer enduring protection against ischemic heart disease and cardiac dysfunction.
背景:癌症幸存者患心血管疾病的风险升高,癌症治疗后缺乏运动可能会加剧这种风险。目的:本研究的目的是调查癌症诊断前后体育活动与心脏病风险之间的关系。方法:对269,943名癌症幸存者(平均年龄56.3岁,45.7%为男性)在诊断前后2年的身体活动依从性进行评估。主要结局是心肌梗死(MI)、心力衰竭(HF)和心房颤动的发生率。采用Gray's方法计算亚分布hr (sHRs)和95% ci,将死亡作为竞争风险。结果:在1,111,329.28人年的随访期间,与不运动的人相比,持续体育锻炼与心肌梗死风险降低20%相关(sHR: 0.80;95% CI: 0.70-0.91), HF风险降低16% (sHR: 0.84;95% ci: 0.78-0.90)。癌症诊断后开始体育锻炼与心肌梗死风险降低11%相关(sHR: 0.89;95% CI: 0.79-0.99), HF风险降低13% (sHR: 0.87;95% ci: 0.82-0.93)。仅在诊断前运动与心肌梗死风险降低20%相关(sHR: 0.80;95% CI: 0.71-0.91), HF风险降低6% (sHR: 0.94;95% ci: 0.88-1.00)。没有观察到体育活动与房颤风险之间的关联。关联因原发癌部位而异。结论:这些发现强调了保持身体活动对癌症幸存者心血管健康的重要性,并表明诊断前的身体活动可能对缺血性心脏病和心功能障碍提供持久的保护。

Background

There are limited data on the physical effects of androgen deprivation therapy (ADT) for prostate cancer (PC), and on the relationships of such measures of adiposity and strength to cardiovascular outcomes.

Objectives

The primary objective of this study was to evaluate the relationships of measures of adiposity and strength to cardiovascular outcomes (cardiovascular death, myocardial infarction, stroke, heart failure, arterial revascularization, peripheral arterial disease, and venous thromboembolism) in patients with PC. A secondary objective was to characterize the relationships between ADT use and 12-month changes in these physical measures.

Methods

This international, prospective cohort study included 3,967 patients with PC diagnosed in the prior 12 months or being treated with ADT for the first time. Median follow-up duration was 2.3 years.

Results

Participants’ mean age was 68.5 years, and 1,731 (43.6%) were exposed to ADT. ADT was associated with a 1.6% increase in weight, a 2.2% increase in waist circumference, a 1.6% increase in hip circumference, a 0.1% increase in waist-to-hip ratio, a 27.4% reduction in handgrip strength, and a 0.1% decrease in gait speed. High waist circumference and low handgrip strength were associated with adverse cardiovascular outcomes. Adjusting for age, education, race, tobacco and alcohol use, physical activity, cardiovascular disease, glomerular filtration rate, and ADT use, waist circumference above the highest quartile (110 cm) and handgrip strength below the lowest quartile (29.5 kg) were associated with higher likelihoods of a future cardiovascular event, with respective HRs of 1.40 (95% CI: 1.03-1.90; P = 0.029) and 1.59 (95% CI: 1.14-2.22; P = 0.006).

Conclusions

ADT was associated with increased adiposity and reduced strength over 12-month follow-up. High waist circumference and low baseline strength were associated with future adverse cardiovascular outcomes.
背景关于雄激素剥夺疗法(ADT)对前列腺癌(PC)患者的身体影响,以及这些脂肪和力量指标与心血管预后之间关系的数据十分有限。目标本研究的主要目标是评估PC患者的脂肪和力量指标与心血管预后(心血管死亡、心肌梗死、中风、心力衰竭、动脉血管再通、外周动脉疾病和静脉血栓栓塞)之间的关系。这项国际性前瞻性队列研究纳入了 3967 名在过去 12 个月内确诊为 PC 或首次接受 ADT 治疗的患者。结果参与者的平均年龄为68.5岁,其中1731人(43.6%)接受过ADT治疗。ADT与体重增加1.6%、腰围增加2.2%、臀围增加1.6%、腰臀比增加0.1%、手握力下降27.4%和步速下降0.1%有关。高腰围和低握力与不良心血管后果相关。在对年龄、教育程度、种族、吸烟和酗酒、体力活动、心血管疾病、肾小球滤过率和 ADT 使用情况进行调整后,腰围高于最高四分位数(110 厘米)和握力低于最低四分位数(29.结论 在 12 个月的随访中,ADT 与肥胖增加和力量下降有关。高腰围和低基线力量与未来心血管不良后果有关。
