High-technology cardiac procedures: the impact of service availability on service use in New York State

Article Abstract:

Treatment of patients who have had a heart attack may vary depending on the availability of different high-technology cardiac procedures at the hospital. These procedures include cardiac catheterization, coronary artery bypass surgery and percutaneous transluminal coronary angioplasty (PTCA). Among 9,576 patients admitted to New York State hospitals for a heart attack between Mar and Jun 1986, 65% were admitted to a hospital that offered none of the procedures, 16% were admitted to a hospital that offered cardiac catheterization only and 18% were admitted to a hospital that offered all three procedures. Patients admitted to a hospital offering cardiac catheterization only were more likely to have this procedure than those admitted to a hospital offering none of the procedures. Patients admitted to a hospital offering all three procedures were more likely to have cardiac catheterization, bypass surgery or PTCA than those admitted to a hospital offering none of the procedures.

Balloon angioplasty in acute and chronic coronary artery disease

Article Abstract:

The use of percutaneous transluminal coronary angioplasty (PTA), a procedure which stretches or dilates a blood vessel by inserting a balloon catheter and inflating it to flatten placque against the artery wall, has grown exponentially since its introduction. Currently, the procedure is used to treat disease of heart vessels, unstable angina and heart attack. The outcome depends on both patient and vessel characteristics, with a 90 percent success rate under the best circumstances. Many issues remain unresolved, including the value of PTA as compared to coronary surgery; the possibility of continued narrowing of the arteries or veins, which occurs in approximately 30 percent of treated lesions; and proper training and certification to maintain high standards of care.

Coupling drug and catheter therapy for myocardial infarction

Article Abstract:

Reperfusion strategies for acute myocardial infarction (MI) remain subject to considerable limitations. Comparing fibrinolysis with primary percutaneous coronary intervention (PCI) in general have shown the latter to be associated with lower rates of death or reinfarction and diminished hemorrhagic complications.
