Hello! Try the Health Source database. I had success with "sleep" as a subject and "cardiovascular" as a keyword. " Other subject headings that retrieved relevant results were:
CARDIOVASCULAR system -- Diseases -- Risk factors
SLEEP apnea syndromes
SLEEP disorders
If you need further assistance, please feel free to call me here at the library (610-282-1100, x1443). I'll be here until 4 pm today (Saturday).
Best,
Lynne
