Insights
Hypertension management after hospitalization for ischemic heart disease (IHD) is suboptimal. Factors like irregular health checks and alcohol use impact treatment, while age and awareness affect blood pressure control.
Area of Science:
- Cardiology
- Hypertension Research
- Public Health
Background:
- Hypertension is a significant risk factor for ischemic heart disease (IHD).
- Effective hypertension management is crucial for secondary prevention in IHD patients.
- Limited data exists on factors influencing hypertension control in IHD survivors.
Purpose of the Study:
- To investigate factors associated with hypertension management in patients hospitalized for IHD.
- To identify predictors of suboptimal blood pressure control post-discharge.
Main Methods:
- Retrospective review of 1051 IHD patient records (myocardial infarction, unstable angina, PCI, CABG).
- Follow-up interviews conducted 6-18 months post-discharge.
- Statistical analysis to identify factors influencing hypertension diagnosis, treatment, and control.
Main Results:
- 70.2% of patients had hypertension; 17.5% were undiagnosed during hospitalization.
- 7.1% of hypertensive patients received no antihypertensive medication.
- Irregular health checks, alcohol use, and unstable angina predicted lack of medication.
- Older age and hypertension awareness predicted uncontrolled hypertension.
Conclusions:
- Hypertension management in IHD secondary prevention requires improvement.
- Age and patient awareness are key determinants of blood pressure control quality post-discharge.
Unlabelled:
Not much is known about factors influencing hypertension management in patients with ischaemic heart disease (IHD). Therefore, the aim of the study was to assess factors influencing hypertension management in patients hospitalized due to IHD. We reviewed hospital records of 1051 consecutive patients with a discharge diagnosis of myocardial infarction (MI; n = 290), unstable angina (n = 247), percutaneous coronary intervention (PCI; n = 259) or coronary artery bypass grafting (CABG; n = 255) who were hospitalized at three university (n = 533) or three community (n = 518) cardiac departments. During the follow-up interview (6-18 months after discharge) 70.2% of study participants fulfilled the criteria for a diagnosis of hypertension. Hypertension had not been diagnosed during index hospitalization in 17.5% of hypertensive participants. Overall, 7.1% of hypertensives were not treated with any blood pressure lowering agent. Irregular health checks (odds ratio, OR, 16.3, 95% confidence interval, CI, 4.1-64.0), alcohol drinking (OR 3.3, 95% CI 1.5-7.0), unstable angina (OR 2.7, 95% CI 1.3-5.8), hypertension awareness (OR 0.2, 95% CI 0.1-0.5) and blood pressure lowering drugs prescribed at discharge (OR 0.08, 95% CI 0.03-0.19) were significantly related to the probability of not being on antihypertensive medication. High blood pressure (>or=140/90 mmHg) was found in 68.9% of hypertensives; older age (OR 1.3, 95% CI 1.0-1.6) and hypertension awareness (OR 0.6, 95% 0.3-1.0) were the only significant predictors of uncontrolled hypertension. Among treated participants with uncontrolled hypertension, 33.4% were on monotherapy, 66.6% were on combination therapy, 25.5% were on three or more drugs and 14.7% were on combination of three or more drugs with diuretic.
Conclusions:
Hypertension management in the secondary prevention of IHD is not satisfactory. Age and hypertension awareness are the main factors related to the quality of blood pressure control in the post-discharge period.
