Characterisation of the Biochemical Profile and Physiology of the Coronary Circulation in Takotsubo Syndrome (TAKO-PROVE)

October 31, 2024 updated by: A.O.U. Città della Salute e della Scienza
Consecutive consenting patients over the age of 18 years diagnosed with Takotsubo syndrome according to the position statement of the European Journal of Heart Failure (2016) will be included in the study. The primary endpoint is to evaluate the incidence of coronary microcirculation dysfunction and its correlation with the clinical presentation and the prognosis in patients with TAKO-Tsubo syndrome. Secondary endpoints will be to assess the incidence of in-hospital mortality, the prevalence of cardiogenic shock, the correlation between the levels of biomarkers analyzed, microvascular dysfunction, perceived quality of life, and angina severity during hospitalization and at subsequent follow-ups, and the influence of knowledge of the level of microvascular dysfunction on clinical management and prescribed therapies. Enrolment: 2 years, follow-up: 1 month and 1 year. Total: 3 years.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Estimated)

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

  • Adult
  • Older Adult

Design Details

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
Incidence of coronary microcirculation dysfunction
Time Frame: one year
coronary microvascular dysfunztion will be defined as a coronary flow reserve (CFR) < 2.5 and/or as an index of microvascular resistance (IMR) > 25 , as assessed with Coroventis syestem
one 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
Incidence of in-hospital mortality
Time Frame: up to thirty days
all-cause death
up to thirty days
Correlation between the levels of biomarkers analysed and microvascular dysfunction
Time Frame: at discharge (assessed up to 5 days)
Several biomarkers (namely neuropeptide Y, troponin I, nt-pro BNP) will be measured via center-specific labratory essays) and a correlation of their blood levels with coronary microvascular dysfunction ( coronary flow reserve (CFR) and index of microvascular resistance (IMR) assessed with Coroventis system) will be sought
at discharge (assessed up to 5 days)
Perceived quality of life
Time Frame: one year
Assessed with Euro Quality of life scale 5D (EQOL-5d): EQ-5D descriptive system is a preference-based HRQL measure with one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort,and anxiety/depression. The answers given to ED-5D permitto find 243 unique health states or can be converted into EQ-5D index an utility scores anchored at 0 for death and 1 for perfect health. The EQ-5D questionnaire also includes a Visual Analog Scale (VAS), by which respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possiblehealth status).
one year
Severity of angina
Time Frame: one year
assessed with the Seattle Angina Questionnaire (SAQ): This SAQ quantifies 5 domains measuring the impact of angina on patients' health status: Physical Limitation (9 items), Angina Stability (1item), Angina Frequency (2 items), Treatment Satisfaction (4 items), and Quality of Life (3 items). Item responses are coded sequentially from worst to best status and range from 1 to 6 for Physical Limitation, Angina Stability, and Angina Frequency items; 1 to 5/6 for Treatment Satisfaction items; and 1 to 5 for Quality of Life items

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.

Primary Completion (Estimated)

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.
