Background: The incidence of cardiovascular disease increases with age, and visits by elderly patients to the outpatient cardiac clinic are becoming more frequent.

Objectives: To characterize cardiovascular pathologies of patients 70 years of age and over who visit the outpatient cardiac clinic.

Methods: We investigated cardiovascular pathologies, risk factors, and medications in new patients over a 2 month period.

Results: The study population comprised 290 patients: 139 (47.9%) were older than 70 years. Among the cardiovascular pathologies, aortic stenosis, angina pectoris, congestive heart failure, s/p coronary artery bypass graft, and stroke were more frequent in the elderly patients than in those under age 70. Among the risk factors for ischemic heart disease, only hypertension was more frequent in the elderly population, whereas fewer in this group were active smokers. The mean number of medications administered was 3.51 ± 1.63 among the elderly patients compared to 1.99 ± 1.71 among the younger ones (P = 0.0001). Beta-blockers were the most frequently used cardiovascular drugs both in the elderly (59.7%) and in the younger patients (43%) (P = 0.0046).

Conclusions: Patients over age 70 represent about half the visits in our outpatient clinic. Their multiple cardiovascular pathologies and therapeutic requirements raise the issue of developing the cardiology service to meet the special needs of geriatric patients.
 

Background: Current clinical guidelines restrict catheterization laboratory activity without on-site surgical backup. Recent improvements in technical equipment and pharmacologic adjunctive therapy increase the safety margins of diagnostic and therapeutic cardiac catheterization.

Objective: To analyze the reasons for urgent cardiac surgery and mortality in the different phases of our laboratory’s activity in the last 11 years, and examine the impact of the new interventional and therapeutic modalities on the current need for on-site cardiac surgical backup.

Methods: We retrospectively reviewed the mortality and need for urgent cardiac surgery (up to 12 hours post-catheterization) through five phases of our laboratory’s activity: a) diagnostic (years 1989–2000), b) valvuloplasties and other non-coronary interventions (1990–2000), c) percutaneous-only balloon angioplasty (1992–1994), d) coronary stenting (1994–2000), and e) use of IIb/IIIa antagonists and thienopiridine drugs (1996–2000).

Results: Forty-eight patients (0.45%) required urgent cardiac surgery during phase 1, of whom 40 (83%) had acute coronary syndromes with left main coronary artery stenosis or the equivalent, and 8 (17%) had mechanical complications of acute myocardial infarction. Two patients died (0.02%) during diagnostic procedures. In phase 2, eight patients (2.9%) were referred for urgent cardiac surgery due to either cardiac tamponade or severe mitral regurgitation, and two patients (0.7%) died. The combined need for urgent surgery and mortality was significantly lower in phase 4 plus 5 as compared to phase 3 (3% vs. 0.85%, P = 0.006).

Conclusion: In the current era using coronary stents and potent antithrombotic drugs, after gaining experience and crossing the learning curve limits, complex cardiac therapeutic interventions can safely be performed without on-site surgical backup.
