Objective: The aim of this study was to evaluate the effect of acupressure applied before CA procedure on systolic and diastolic blood pressure, mean arterial pressure, pulse and pain intensity parameters after CA.

Design: The study is a randomized controlled trial. Setting: The study occurred at Cardiology Service (CS) of a Training and Research Hospital in Turkey.

Participants: One hundred patients whomet the research criteria.

Heart disease is the most important cause of mortality and morbidity in developed and developing countries, despite all preventive and therapeutic initiatives and newly developed methods.Besides the drug treatments, interventional procedures are also used to diagnose and treat some heart diseases, which are life-saving and have few risks. CA, one of the interventional methods commonly used for this purpose, is the process of obtaining cine-angiographic images by injecting contrast agents into femoral, brachial, radial, axillary arteries.

People experience fear of death and consequent anxiety because CA is an invasive diagnostic method. There is a lot of uncertainty about the procedure, and the usage of this method in the diagnosis of an organ with high vital importance, such as the heart, causes fear.High levels of stress cause cardiac irritability and increased blood pressure; while anxiety and stress persist, temporary myocardial ischemia, increased heart rate, palpitations, and chest pain may develop.

The aim of nursing care in CA patients is to ensure the relief and comfort of the patient before, during, and after the procedure, to determine and prevent complications that may develop at an early stage.It is noted that reducing anxiety and pain before and after CA is essential in ensuring the stability of vital signs. Acupressure used for this purpose is a non-pharmacological nursing initiative that can relieve and reduce pain and regulate anxiety-related blood pressure. This study evaluates the impact of acupressure applied before CA on systolic and diastolic blood pressure, mean arterial pressure, pulse, and pain severity parameters after CA.

Design: The study was a randomized controlled trial. Setting: The study occurred at Cardiology Service (CS) of a Training and Research Hospital in Turkey.

Participants: One hundred patients, met the research criteria were divided into 50 in the intervention (IG) and 50 in the control group (CG) by simple randomization method.

Intervention: The IG received acupressure and the CG received no acupressure. Acupressure was applied to patients in the IG 30-60 minutes before CA. In the study the Li4, HT7, and Extra 1 acupressure points and repeated measures were selected; pain intensity, systolic and diastolic blood pressure and pulse parameters of the patients were measured three times.
