Özet
Amaç: Çalışmamızın amacı hafif hipertansif hastalarda sağ ventrikül diyastolik fonksiyonlarına septum ve sağ ventrikül serbest duvarının etkisini standard ve renkli doku Doppler ekokardiyografi yöntemi ile araştırmaktır. Gereç ve Yöntem: Çalışmaya 31 hafif hipertansif hasta, (sistolik kan basıncı= 144±11 mmHg, diyastolik kan basıncı= 91±9 mmHg, yaş ortalaması 52±12 yıl, 10 erkek, 21 kadın) ile yaş-eşleştirmeli 30 sağlıklı (sistolik kan basıncı= 113±9 mmHg, diyastolik kan basıncı= 62±6 mmHg, yaş ortalaması 47±7 yıl, 14 erkek, 16 kadın) birey alındı. Tüm parametreler standart ve renkli doku Doppler ekokardiyografi ile ölçüldü. Bulgular: 31 hastanın 17'sinde (%54) sol ventrikül diyastolik fonksiyon bozukluğu, 16'sında (%52) ise sağ ventrikül diyastolik fonksiyon bozukluğu tespit edildi. Septum duvar kalınlığı (p<0.05), sol ventrikül arka duvar kalınlığı (p<0.05), sol ventrikül kitlesi (p<0.05), sol ventrikül kitle indeksi (p<0.05) ve sağ ventrikül serbest duvar kalınlığı (p<0.001) hipertansif grupta kontrol grubuna göre artmıştı. Sağ ve sol ventrikül diyastolik doluş parametreleri arasında birebir ilişki bulundu (Mitral E- Triküspid E r= 311 p0.015, Mitral A- Triküspid A r= 371 p0.003, Mitral E/A- Triküspid E/A r= 537 p0.001). Sağ ventrikül diyastolik doluş parametreleri ile sağ ventrikül serbest duvar renkli doku Doppler ekokardiyografik diyastolik parametreleri arasında anlamlı ilişki bulunmamasına rağmen, septumun renkli doku Doppler diyastolik parametreleri ile triküspid Et/At oranı arasında anlamlı ilişki bulundu. Sonuç: Hafif hipertansif hastalarda sağ ventrikül diyastolik fonksiyonları bozulmaktadır. Sağ ventrikül diyastolik fonksiyonu üzerine septum, sağ ventrikül serbest duvarına göre daha etkilidir.
Aim: In this study, we aimed to investigate effect of septum and right ventricular free-wall on right ventricular diastolic function in patients with mild hypertension by standard and color tissue Doppler echocardiographic methods. Material and Methods: The study group was consisted of 31 mild hypertensive patients (systolic blood pressure/diastolic blood pressure= 144±11/91±9 mmHg, mean age 52±2 years, 10 men, 21 women) and 30 age- matched normotensive control subjects (systolic blood pressure/diastolic blood pressure= 113±9/62±6 mmHg, mean age 47±7 years, 14 men, 16 women). All the parameters were measured with standard and colour tissue Doppler echocardiography. Results: Left ventricular diastolic dysfunction in 17 of 31 patients (54%) and right ventricular diastolic dysfunction in 16 of 31 patients (52%) were found. Septum (p<0.05), left ventricular posterior wall (p<0.05), left ventricular mass (p<0.05), left ventricular mass index (p<0.05) and right ventricular free-wall thickness (p<0.001) statistically increased in hypertensive groups than control groups. Significant correlations were observed between parameters of right and left ventricular filling in hypertensive patients (Mitral E- Tricuspid E r= 311 p0.015, Mitral A- Tricuspid A r= 371 p0.003, Mitral E/A- Tricuspid E/A r= 537 p0.001). Although no correlation was found between parameters of the diastolic filling of right ventricular and diastolic parameters of right ventricular free-wall by tissue Doppler echocardiography, significant correlation was found between tricuspid E/A ratio and diastolic parameters of septum by colour tissue Doppler echocardiography Conclusion: Right ventricular diastolic function is impaired in mild systemic hypertension. Septum is more effective than right ventricular free-wall on right ventricular diastolic function.
