An Updated Report From the Hungarian Ambulatory Blood Pressure Monitoring Registry

Objective: Ambulatory blood pressure monitoring (ABPM) is recommended by current European guidelines for the early diagnosis of hypertension and to monitor the efficacy of antihypertensive treatments. The Hungarian Society of Hypertension has initiated a 5-year, nationwide program in 2021 to promote the routine use of ABPM and to improve the motivation of doctors and patients. This is an updated report on the Hungarian ABPM Registry. Design and method: This is an ongoing, multicenter, open-label, observational study. Adult (age >18 years) patients with known hypertension(HT), or with suspected/newly diagnosed hypertension(nHT) can be involved in the study. ABPM monitoring is performed by GPs, internists, and cardiologists using validated Meditech ABPM-06 monitors. Current report analyzed ABPM data between 21.02.2021-16.11.2023, that were collected into an electronic case report. Overall, 40621 ABPMs were performed, due to protocol deviation 1901 patients were excluded from the analysis. Results: 26315 patients were HTs(68.3%), 12193 patients were nHTs(31.5%). In the HT group 95.5%, in the nHT group 21.5% were treated. 63.6% of all patients were hypertensives according to the 24-hour average blood pressure(BP) values. Mean 24-hour systolic and diastolic BP was 133.84±14.5 mmHg and 79.2±10.3 mmHg, respectively. There was no difference in the 24-hour mean systolic BP between HT and nHT patients (133.75±13.96mmHg vs. 133.86±14.72mmHg, respectively, p=NS). Obesity(BMI >30 kg/m2) increased the risk of hypertension(OR=1.821.73;1.92for 24-hour average). Coffee consumption(more than 3/day)(OR=1.221.16;1.29for 24-hour average), snoring(OR=1.391.33;1.46for 24-hour average)and smoking(OR=1.101.03;1.18for 24-hour average)all increased the risk of hypertension, primarily affecting more the daytime BP values(OR=1.241.18;1.31for daytime in coffee consumption, OR=1.131.07;1.19for nighttime in coffee consumption; OR=1.421.36;1.49for daytime in snoring, OR=1.311.25;1.38for nighttime in snoring; OR=1.091.01;1.16for daytime in smoking, OR=1.010.94;1.08for nighttime in smoking (NS)). Lack of regular sport(less than 3x30 minutes weekly)increased the risk of hypertension(OR=1.111.05;1.18for 24-hour average), primarily affecting more the nighttime values(OR=1.191.12;1.26for nighttime, OR= 1.020.96;1.07for daytime(NS)). Conclusions: Hypertension is highly prevalent in both HT and nHT patients, irrespectively of gender or treatment. Obesity, lack of regular sport, coffee consumption, snoring and smoking are all significant risk factors in developing hypertension, latter ones affecting more the daytime BP values, whereas lack of regular sport affects more the nighttime BP values.
