Retrospective Cohort Study on Post Analysis on the Link Between the Clinical Heart Rate and Outcomes During PCI

January 27, 2015 updated by: Dandan Li

A Single Centre, Retrospective Cohort Study on Post Analysis on the Link Between the Clinical Heart Rate and Outcomes During PCI

The trial is a single centre, retrospective cohort, non-interventional study to be conducted in the department of cardiology, Chinese PLA General Hospital, Beijing, China. To evaluate the link between mean perioperative clinical heart rate and short-term composite outcomes during PCI among local CHD patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The study requires those data including subjects aged from 20 to 80 year-old, diagnosed as coronary heart disease with records on mean clinical heart rate during PCI from 2009.1 to 2014.5 in the database from the department of cardiology, Chinese PLA General Hospital, Beijing. All 15,000 subjects' related data from the database will be collected.Once selected, 15,000 patients in the retrospective cohort will be divided into 4 groups according to their mean clinical resting heart rate during PCI. Group 1 will be defined as subjects' mean clinical resting heart rate ≤70 BPM, which will be set as baseline. Group 2 will be defined as subjects' mean clinical resting heart rate between 71 to 80 BPM. Group 3 will be defined as subjects' mean clinical resting heart rate between 81 to 90 BPM. Group 4 will be defined as subjects' mean clinical resting heart rate >90 BPM. The primary endpoint is to determine the link between the mean perioperative heart rate and short-term outcomes during PCI among local CHD patients.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Heart rate ≤70bpm

Heart rate between 71 to 80bpm
15,000 patients in the retrospective cohort will be divided into 4 groups according to their mean heart rate during PCI. Group 2 will be defined as subjects' mean heart rate between 71 to 80bpm.
Heart rate between 81 to 90bpm
15,000 patients in the retrospective cohort will be divided into 4 groups according to their mean heart rate during PCI. Group 1 will be defined as subjects' mean heart rate between 81 to 90bpm.
Heart rate>90bpm

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Proportion of patients with composite events including CVD mortality, fatal/non-fatal MI, non-fatal sudden cardiac arrest, fatal/non-fatal stroke and malignant arrhythmia
Time Frame: During PCI
During PCI

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mean perioperative clinical heart rate
Time Frame: During PCI
The primary efficacy endpoint is proportion of patients with composite events including CVD mortality, fatal/non-fatal MI, non-fatal sudden cardiac arrest, fatal/non-fatal stroke and malignant arrhythmia.
During PCI
Clinical resting heart rate and heart rate variability
Time Frame: During PCI

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2015

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
