Cardiac Vulnerability in Potentially Susceptible Patients
September 1, 2006 updated by: National Institute of Environmental Health Sciences (NIEHS)
This project is part of a program project directed toward assessing cardiac effects of particulate and other ambient air pollutants.
In this project patient who have recently suffered a cardiac event are being monitored with cardiac monitors for 24 hours up to 4 times during the year following their cardiac event.
Similarly a second group of patients with moderate to severe heart failure will undergo similar cardiac monitoring for 24 hours, twice a week separated by 3 months.
In both sets of patients home indoor pollution measures will be continuously made and used to correlate with measures of heart rate variability.
Study Overview
Status
Completed
Conditions
Detailed Description
Approximately 50 patients in each group will be studied.
In addition to cardiac monitoring for 24 hours at each session, overnight respiratory pattern and oxygen saturation will be monitored in both groups.
The exposure monitoring will include both particle mass of PM2.5 along with detailed assessment to determine that portion of the particulate exposure from outdoor vs. indoor sources.

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
Ages Eligible for Study
45 years to 74 years (Adult, Older Adult)
Accepts Healthy Volunteers
No
Genders Eligible for Study
All
Description
For the cardiac event cases patients are selected from the Brigham and Women's Hospital cardiac services at the time of discharge, aged 45-74, having suffered a cardiac event resulting in either an infarct or need for a cardiac procedure (angioplasty, stint, etc).
For the CHF patients they are selected from the BWH cardiac clinics where they have been identified and classified as stage 3 or 4 CHF.
For both groups residence requirements are that they reside within the Greater Boston Area as defined by an outer ring road (Route 495) and are willing to be visited at home and have the exposure assessment equipment set up in their home as well as be monitored personally.
