Cohort Study of Heart Failure With Preserved Ejection Fraction in Chinese Han

March 3, 2022 updated by: Nanjing First Hospital, Nanjing Medical University
To analyze factors contributing to the development and prognosis of heart failure with preserved ejection fraction.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Based on previous studies on development of heart failure with preserved ejection fraction (HFpEF), racial/ethnical background should be underscored when evaluating risk f actors for HFpEF incidence. As the ageing population increases sharply in China, HFpEF represents the dominant phenotype of all patients diagnosed with heart failure. In this cohort study, the investigators evaluated exposures or risk factors for HFpEF in Chinese Han patients with cardiovascular diseases (CVD). Our study may provide preventive and therapeutic targets for HFpEF in Chinese CVD patients.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Study Population

Subjects were enrolled from Nanjing First Hospital, a public tertiary care university hospital in Nanjing, China.

Description

Inclusion Criteria:

  • Patients with CVD, defined as at least one diagnosis of coronary heart disease, hypertension, type 2 diabetes or cardiomyopathy. The definition of coronary heart disease was stenosis of the main coronary arteries ≥ 50% using percutaneous coronary angiography or coronary computed tomography angiography findings. The definition of hypertension was systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg or pharmacological treatment. The definition of type 2 diabetes was fasting blood glucose ≥ 7.0 mmol/L, random blood glucose ≥ 11.1 mmol/L and HbA1c > 6.5% or the or the use of hypoglycaemic medications. Cardiomyopathy was defined as the presence of cardiac insufficiency in patients with dilated cardiomyopathy suggested by percutaneous coronary angiography or coronary CT angiography use of hypoglycaemic medications.

Exclusion Criteria:

  • primary diagnoses of atherosclerosis (stenosis of the main coronary arteries < 50%), congenital heart diseases, arrhythmia, lung diseases, aortic dissection, peripheral vascular diseases, pericardial diseases, myocarditis, hypertrophic cardiomyopathy, heart valvular diseases, cardiophobia, costal chondritis, shock, thyroid diseases, infection or concomitant liver or renal dysfunction.

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
Measure Description
Time Frame
One minute sit-to-stand test (1-min STST)
Time Frame: up to 4 weeks
Briefly, each subject was instructed in sitting position to extend both knees at the same time, starting from a 90° knee flexion position to a 180° extension, which works the thigh muscles, and especially the quadriceps.
up to 4 weeks
Worsening of heart failure (HF)
Time Frame: an average of 1 year
worsening of symptoms defined as either failure to improve (persistent symptoms and signs of acute HF during treatment) or recurrent symptoms and signs of acute HF, pulmonary edema, or cardiogenic shock after initial stabilization , either of which requiring increased use of diuretics (as outpatient or inpatient), addition of a new intravenous therapy (diuretics, inotrope, or vasodilator) or mechanical support
an average of 1 year
Hospitalization due to worsening of heart failure (HF)
Time Frame: an average of 1 year
hospitalization due to worsening HF requiring intravenous pharmacological agents (inotrope or vasodilator), mechanical ventilation, mechanical support or ultra- filtration, hemofiltration, or dialysis
an average of 1 year

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
all-cause and cardiogenic deaths
Time Frame: an average of 1 year
all-cause and cardiogenic deaths
an average of 1 year

Study Major Dates

Study Start (Actual)

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, 2014

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.
