  Purpose

The objectives of this study are: 1) To determine whether patients with acute coronary syndrome, the level of environmental exposure to particulate air pollutants in the week prior to admission, are related to concentrations of inflammatory molecules and oxidative stress. 2) To investigate whether the level of environmental exposure is an independent prognostic factor in terms of overall and cardiovascular mortality, myocardial infarction or unstable angina at 30 days, 6 and 12 months.


Condition Intervention
Patients With Acute Coronary Syndrome
Other: Particulate air pollutants

Time Perspective: Prospective
Target Follow-Up Duration: 360 Days

Primary Outcome Measures:
  • Impact of air pollution on inflammation, oxidative stress and 1-year prognosis in patients hospitalized for acute coronary syndrome. [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
    A single center, cohort of consecutive patients admitted with diagnosis of acute coronary syndrome in the cardiology unit of a tertiary hospital, which will quantify the exposure of particulate air pollutants 24 hours a day 7 days earlier prior to admission. Also be determined inflammatory molecules and oxidative stress in admission.


Secondary Outcome Measures:
  • Impact of air pollution on inflammation, oxidative stress and 1-year prognosis in patients hospitalized for acute coronary syndrome. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    During the evolution of these patients, after 30 days, 6 and 12 months will recorded major adverse cardiovascular events. It also will quantify the exposure of air pollutant particles in all patients included, at 30 days, 6 and 12 months.


Other Outcome Measures:
  • Impact of air pollution on inflammation, oxidative stress and 1-year prognosis in patients hospitalized for acute coronary syndrome: [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    During the evolution of these patients, after 30 days, 6 and 12 months will recorded major adverse cardiovascular events. It also will quantify the exposure of air pollutant particles in all patients included, at 30 days, 6 and 12 months.


Estimated Enrollment: 307
Study Start Date: November 2011
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Particulate air pollutants
Cohort of consecutive patients admitted with diagnosis of acute coronary syndrome in the cardiology unit of a tertiary hospital, which will quantify the exposure of particulate air pollutants 24 hours a day 7 days earlier prior to admission.
Other: Particulate air pollutants
We will determined the average concentrations of different sizes of particulate matter from 1 day or up to 7 days prior to admission in patients with acute coronary syndrome.

  Eligibility

Ages Eligible for Study:   18 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Cohort of consecutive patients admitted with diagnosis of aucte coronary, which will quantify the exposure of particulate air pollutants 24 hours a day 7 days earlier prior to admission. Also be determined inflammatory molecules and oxidative stress in admission. During the evolution of these patients, after 30 days, 6 and 12 months will recorded major adverse cardiovascular events. It also will quantify the exposure of air pollutant particles, in all patients included at 30 days, 6 and 12 months.

Criteria

Inclusion Criteria:

  • Patients with acute coronary syndrome

Exclusion Criteria:

  • Infectious process and / or local or systemic inflammation in the 15 days before admission.
  • Thyrotoxicosis.
  • Neoplasms - or any other disease that seriously compromise the prognosis of life and / or generate a systemic inflammatory response.
