Abstract

Introduction: Hypertension is a common disease globally and it is of public health significance. The objective was to determine the prevalence and pattern of arrhythmias and the associated factors in adults with systemic hypertension in a tertiary hospital in a resource-constraint setting. Materials and Methods: It was a cross-sectional study which included the resting 12-lead electrocardiograms of adult patients aged 18 years and above with hypertension attending the Cardiology Unit of the Federal Medical Centre, Ido-Ekiti, Nigeria. Results: Resting electrocardiogram of 602 adult Nigerians with hypertension were studied. 340 (56.5%) were males and 262 (43.5%) females. The mean age of the patients was 58.3±10.7 years. Ninety eight (16.3%) patients had arrhythmia. Compared with those without arrhythmia, patients with arrhythmia were older (62.3±12.8 vs. 56.1±13.2, p =0.03 ), had a higher prevalence of QTc prolongation (14.3% vs. 6.0%, p = 0.041) and left ventricular hypertrophy (24.5% vs 12.7%, p = 0.026), and more likely to be in heart failure (32.7% vs. 8.5%, p < 0.001). Conclusion: The study shows a prevalence of 16.3% of arrhythmia among adult Nigerians with hypertension. Premature ventricular complex and atrial fibrillation are the most frequent arrhythmias. Older age, higher systolic and diastolic blood pressure and left ventricular hypertrophy and QTc prolongation are associated with arrhythmia.

Hipertansiyonu Olan Erişkinlerde Kaynak Kısıtlı Ortamda Kardiyak Aritmiler

Abstract

Amaç: Hipertansiyon, tüm dünyada toplum sağlığı önemi olan yaygın bir hastalıktır. Amaç kaynak kısıtlı ortamda, üçüncü basamak hastanede sistemik hipertansiyonu olan erişkinlerde aritmi prevelansı, paternleri ve ilişkili faktörleri belirlemektir. Materyal ve metod: Nijerya, Ido-Ekiti'de Federal Tıp Merkezinin Kardiyloji ünitesine hipertansiyon ile başvuran 18 yaş ve üzeri erişkin hastalarda 12 derivasyonlu istirahat elektrokrdiyogramını kapsayan kesitsel bir araştıradır. Sonuçlar: Altıyüziki (602) erişkin Nijeryalının istirahat elektrokardiyogramı çalışıldı. 340'ı erkek (%56.5) ve 262'i (%43.5) kadındı. Hastalaron ortalama yaşları 58.3±10.7 yıldı. Doksansekiz hastada (%16.3) aritmi mevcuttu. Aritmisi olmayanlar ile karşılaştırıldığında, aritmisi olan hastalar daha yaşlıydı (62.3±12.8 vs. 56.1±13.2, p =0.03), QTc uzaması (14.3% vs. 6.0%, p = 0.041), sol ventriküler hipertrofisi (24.5% vs 12.7%, p = 0.026) prevelansı daha yüksekti ve kalp yetmezliğinde olmaya yatkındı (32.7% vs. 8.5%, p < 0.001). Tartışma: Bu araştırma hipertansiyonu olan erişkin Nijeryalılardaaritmi prevelansının %16.3 olduğunu göstermiştir. Erken ventriküler kompleks ve atrial fibrilasyon en sık aritmilerdir. Daha yaşlı olma, yüksek sistolik ve diastolik kan basıncı ve sol ventriküler hipertrofi ve QTc uzaması aritmi ile ilişkilidir.
