Internal Mammary Artery Implantation for Angina Pectoris

Left ventricular hemodynamics before and 1 year after internal mammary artery implantation in patients with coronary artery disease and angina pectoris.

or more implants providing collaterals to coronary arteries, and 10 had no evidence of collaterals from the implant. Only two patients, both with functioning implants, showed a return to normal of left ventricular end-diastolic pressure at rest and during exercise. There was no correlation between clinical improvement and hemodynamics at the time of the postoperative study. It is concluded that...

Beta-adrenoceptor-mediated responsiveness of human internal mammary artery

The internal mammary artery (IMA) is currently the preferred conduit for myocardial revascularization. However, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. The mechanism of spasm has not been clearly defined. Since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...

Coronary artery stenting in unstable angina pectoris: a comparison with stable angina pectoris.

OBJECTIVE To compare early complication rates in unselected cases of coronary artery stenting in patients with stable v unstable angina. SETTING Tertiary referral centre. PATIENTS 390 patients with stable angina pectoris (SAP) and 306 with unstable angina (UAP). Patients treated for acute myocardial infarction (primary angioplasty) or cardiogenic shock were excluded. INTERVENTIONS 268 cor...
