Efek Cold Pressor Test Terhadap Pasokan dan Kebutuhan Oksigen Miokard Pada Perokok Aktif di Kecamatan Ungaran Kabupaten Semarang

cold pressor test perokok aktif segmen ST dan tekanan darah.

Abstract

Abstrak

Penelitian kuasi eksperimen ini bertujuan menguji pengaruh cold pressor test (CPT) terhadap pasokan dan kebutuhan oksigen miokard pada perokok aktif dengan pengukuran tekanan darah dan segmen ST di Kecamatan Ungaran Kabupaten Semarang. Jumlah sampel dalam penelitian ini sebanyak 76 perokok aktif di Kecamatan Ungaran Kabupaten Semarang dan ditentukan dengan cluster sampling. Pengaruh CPT terhadap tekanan darah dan segmen ST pada perokok aktif diuji dengan dependent sample t test. Hasil penelitian menunjukkan rerata tekanan darah setelah intervensi CPT mengalami penurunan. Hasil analisis dengan uji t test menunjukkan bahwa CPT menurunkan tekanan darah setelah intervensi CPT (p=0,000). Rata-rata segmen ST sebelum dan setelah intervensi CPT tidak jauh berbeda. Hasil uji t test menunjukkan bahwa CPT tidak berpengaruh dalam menurunkan segmen ST pada perokok aktif (p = 0,895). Penelitian ini menyimpulkan bahwa CPT berpengaruh terhadap perubahan tekanan darah pada perokok aktif tetapi tidak berpengaruh terhadap perubahan segmen ST. Selama CPT terjadi peningkatan tekanan darah dan berangsur menurun setelah dilakukan CPT. Segmen ST tidak mengalami perubahan. CPT dapat digunakan oleh perawat untuk memprediksi kejadian peningkatan tekanan darah. Untuk penelitian selanjutnya sebaiknya digunakan alat ukur yang lebih sensitif dan menggunakan determinan pasokan dan kebutuhan oksigen miokard yang lain seperti preload dan denyut jantung.

 

Abstract

This quasy-experimental research was aimed to examine the effect of cold pressor test (CPT) to the myocardial oxygen demand and supply among active smokers in the Ungaran district, Semarang by measuring blood pressure and ST segment. There were 76 active smoker males involved as the cluster sampling in the research. To examine the CPT effect on the blood pressure and ST segment among the active smokers, dependent sample t test was conducted. The result of the research showed that average blood pressure is decreased after CPT. Furthermore, CPT showed its effects on decreasing blood pressure after the intervention (p = 0,000). The averages of ST segment before and after intervention of CPT were slightly different. Thus, CPT indicated no significant impact in decreasing ST segment among active smokers (p = 0,895). The research concluded that CPT caused blood pressure changes among active smokers but do not have effect in ST segment changes. On the other hand, it was observed that the initial blood pressure were increase during CPT but then gradually decreased immediately after the end of CPT. In addition, ST segment remained unchanged. Therefore, the CPT is still beneficial for predicting high blood pressure in patient compared to other cardiac stress test. Nevertheless, it is recommended to use more sensitive device and to consider other determinants of the myocardial oxygen demand and supply such as preload and heart beat for further research.
