未熟心室期外収縮における身体的障害

2026年11月3日 更新者：Gulsah Bargi、Izmir Democracy University

早期心室期外収縮を有する個人における呼吸機能、筋力、身体活動レベル、および生活の質の調査

Premature ventricular complexes may be observed in individuals without underlying disease due to factors such as physical inactivity, advanced age, smoking, male sex, and psychosocial disturbances, and in some cases may result in sudden cardiac death. Therefore, the aim of this study is to investigate respiratory function, respiratory muscle strength, cough strength, handgrip strength, physical activity level, and quality of life in individuals with premature ventricular complexes.

詳細な説明

The primary aim of this study is to comprehensively investigate respiratory function, respiratory muscle strength, cough strength, handgrip strength, physical activity level, and quality of life in individuals with premature ventricular complexes. Additionally, an important secondary aim is to identify potential differences in these parameters between individuals with premature ventricular complexes and healthy controls and to contribute original findings to the existing literature.Participants will be evaluated in terms of these parameters through clinical assessments, questionnaires, and measurements.

  • Physically able to participate in all study assessments

Exclusion Criteria for Individuals with Premature Ventricular Complexes (PVCs):

  • Left ventricular ejection fraction (LVEF) <45% unless PVC-induced cardiomyopathy is documented (defined as a >15% improvement in LVEF following reduction of PVC burden through pharmacological therapy or ablation)
  • Progressive decline in LVEF within the last 4 months, regardless of etiology
  • Severe heart failure classified as New York Heart Association (NYHA) Class ≥III
  • Ventricular arrhythmias attributed to underlying structural heart disease, known myocardial scar, or myocarditis
  • Change in the dosage of antiarrhythmic medications (including β-blockers and calcium channel blockers) within 2 months prior to enrollment
  • Failed catheter ablation within 3 months prior to enrollment
  • Known thyroid disorders or individuals undergoing renal dialysis
  • Life expectancy <12 months
  • Presence of angina pectoris
  • Diagnosis of chronic obstructive pulmonary disease (COPD) or asthma
  • Resting heart rate >120 beats/min
  • Resting systolic blood pressure ≥180 mmHg
  • Resting diastolic blood pressure ≥100 mmHg
  • Resting peripheral oxygen saturation ≤90%

Exclusion Criteria for Control Group Participants:

  • Presence of premature ventricular complexes
  • Presence of any acute or chronic medical condition

介入・治療
Ventricular premature complexes group

This group will consist of individuals with premature ventricular complex.
他の：Physical Evaluations of Patients with Premature Ventricular Complex

In this study, data from individuals with premature ventricular complex will be collected through face-to-face assessments. Respiratory functions, respiratory and peripheral muscle strength, cough strength, physical activity level, and quality of life will be assessed in these individuals who meet the inclusion criteria. All data obtained through these assessments will be collected from participants face-to-face at one time and for a maximum of approximately 1 hour.
Control Group

This group will consist of healthy individuals.
他の：Physical Evaluations of Healthy Individuals

In this study, data from healthy individuals will be collected through face-to-face assessments. Respiratory functions, respiratory and peripheral muscle strength, cough strength, physical activity level, and quality of life will be assessed in these individuals who meet the inclusion criteria.All data obtained through these assessments will be collected from participants face-to-face at one time and for a maximum of approximately 1 hour.

Cough Strength
時間枠：through study completion, an average of 1 year

Participants' peak cough expiratory flow (PCEF) values will be assessed in an upright sitting position using a peak cough flow meter (ExpiRite Peak Flow Meter, China). Following a deep inspiration, participants will be instructed to cough as forcefully as possible into the device. The best value obtained from at least three trials will be recorded.

Handgrip Strength
時間枠：through study completion, an average of 1 year

Maximum isometric strength of the hand and forearm muscles will be measured using a hydraulic hand dynamometer.Measurements will be performed in an upright sitting position in accordance with guidelines. The mean of the three measurements for the right and left hands will be used for analysis.

Assessment of Physical Activity
時間枠：through study completion, an average of 1 year

Participants' physical activity levels over the previous seven days will be assessed using the International Physical Activity Questionnaire-Short Form. The questionnaire consists of 7 items that assess time spent walking, and moderate- and vigorous-intensity physical activities over the last seven days. Total physical activity scores will be calculated by summing the duration (minutes) and frequency (days) of walking, moderate-intensity, and vigorous-intensity activities. Total physical activity score will be expressed as metabolic equivalent task minutes per week (MET-min/week).
through study completion, an average of 1 year
Assessment of Quality of Life
時間枠：through study completion, an average of 1 year

Participants' quality of life will be evaluated using the Short Form-36 Health Survey (SF-36). The SF-36 assesses eight health domains: general health, physical functioning, role limitations due to physical problems, role limitations due to emotional problems, social functioning, bodily pain, vitality, and mental health, along with one additional item assessing health transition. Participants will be instructed to respond to each question in a manner that best reflects their current condition, and researchers will provide clarifying guidance when necessary.
through study completion, an average of 1 year
