With the aging of the social population and poor lifestyle, the incidence of coronary heart disease (CHD) continues to rise, and coronary intervention (PCI) has become an important means of treating CHD [14] , the surgical method includes the transradial artery and the transfemoral artery, in which the transfemoral approach is the traditional surgical method.

Patients after the radial artery intervention, because the surgical site is in the upper limb, the ambulation is not limited, only the postoperative puncture site of the upper limb radial artery compression hemostasis immediately. It has been shown that in patients undergoing coronary intervention via transradial access, the radial artery compression hemostasis time 2 h is the best time, the hemostasis efficacy (prevention of RAO) and safety (prevention of hematoma/rebleeding in access site) are consistent with conventional compression for 6 - 12 h [15] .

At present, in China, patients are often required to press with sandbags for 6 - 8 h and brake in bed for 24 h after transfemoral artery intervention [16] . However, long-term bed rest brings discomfort to patients and delays the rehabilitation process. Internationally, the early postoperative activity time of CHD patients is not clear. Kobrossi et al. [17] study showed that early activity (3 h) and standard (6 h) had similar and low rates of vascular complications, cardiac catheterization laboratories are encouraged to adopt an early policy after femoral CC/PCI to improve patient comfort and accelerate patient discharge. In addition, Wentworth et al. [18] study also showed that there was no statistical difference in the reduction in bed rest time from 6 h to 4 h for puncture site-related complications after transfemoral PCI. Regarding the operative limb brake time, the study of Santos et al. [19] showed that the reduction of limb fixation after transfemoral PCI from 4 h to 2 h did not change the frequency and intensity of pain, the need for analgesic drugs and the incidence of urinary retention, and the incidence of dry hematoma had no obvious clinical manifestations. Wang et al. [20] study showed that the patient was ambulating 2 - 3 h after the transfemoral approach intervention (sheath model: 5 - 7 Fr), which reduced the back pain intensity and urinary system discomfort. The study of Ibdah et al. [21] showed that early position changes 1 h after cardiac catheter removal can reduce back pain and dysuria and increase patient comfort without increasing the occurrence of vascular complications such as bleeding and hematoma, which has a significant positive impact on patient prognosis. Suggs et al. [22] studies have shown that a bedside elevation of 20˚ immediately after the removal of cardiac catheterization can improve postoperative pain without increasing bleeding or complications. All the above studies showed that returning to the ward for 1 h or even raising the bedside immediately; reducing the bed rest to 3 - 4 h was more applicable than the conventional long bed rest. The shortening of postoperative bed-rest time can be related to the popularization of PCI and the continuous update of surgical instruments. Therefore, after femoral artery intervention, the head of the bed can be raised 1 h after removing the sheath, and it can move out of bed 3 to 4 h after surgery.

Cardiac radiofrequency ablation (radiofrequency catheter ablation, RFCA) is the main clinical treatment of arrhythmia, in which the transfemoral artery/femoral vein route is a common treatment route. However, complications such as puncture site bleeding, hematoma, and pseudoaneurysm can occur after femoral RFCA [23] , so bed rest is required to control the risk of complications. At present, there is no unified regulation on bedtime after femoral RFCA at home and abroad, and literature reports range from 1.5 to 24 h [24] [25] . Domestic guidelines suggest that bed rest and limb braking for 6 h after femoral vein RFCA [26] , However, there is no uniform standard for postoperative bed rest and early activity in clinical practice.

Transfemoral RFCA early activity, one study [27] showed that transfemoral radiofrequency ablation recommends 12 h ambulation. Li et al. [26] an evidence-based practice concluded that the PRCA should be bedridden for 3 to 4 h, 4 h after bed mobilization, 6 to 12 h can reduce the incidence of patients’ pain, difficulty in urination and other complications, and greatly improve the patients’ medical experience and prognosis. In addition, foreign studies on transfemoral heart interventional surgery [28] [29] also show that early position changes, postoperative return to the ward bed elevation 15˚, 30˚ can relieve patients’ low back pain and uncomfortable feeling. Liang et al. [30] the results of a study on an evidence-based practice project also showed that patients with transfemoral puncture cerebral angiography began to change the lying position 2 h after surgery, and 6 hours could significantly increase the comfort and reduce the level of pain after surgery without changing the incidence of vascular complications. Transfemoral RFCA and femoral angiography are consistent with compression and hemostasis, but RFCA is usually more complex and requires longer surgical time. Therefore, the first postoperative implantation time is prolonged, so according to the actual situation of the patient, it is suggested that patients with femoral RFCA should brake in bed for 3 to 4 h after femoral radiofrequency ablation, during which the bed can be raised for 15˚ and 30˚, move in bed for 4 h, and get out of bed for 6 to 12 h.

In China, the RFCA was generally braking for 6 to 12 h, and the implantation time was 12 to 24 h after surgery [31] [32] . However, theoretically, the risk of bleeding at the site of femoral vein puncture is less than that of the femoral artery, and it is also easier to achieve hemostasis. Therefore, more studies have compared the effects of relieving postoperative immobilization and early ambulation in a shorter period of time. Zhu et al. [33] the study showed that patients with vascular stapler brake for 2 h after surgery and stay in bed for 6 h after rest; the bedside is raised for 15, and turn over every 2 h to help change position. Compared with the patients who are regularly in bed for 12 h, it effectively promoted the early ambulation and rehabilitation process, and shortened the hospitalization time. Li et al. [34] - [36] the study showed that the head of the bed was raised to 15˚ at 1 h after surgery, then the head of the bed was gradually raised to 45˚, and the left and right sides were turned over alternately, which could effectively relieve the back pain, shorten the hospital stay and improve the satisfaction of patients. Tan’s research [33] - [37] showed that the turning and bed movement within 4 h to 6 h can effectively improve the comfort and meet the physiological needs of 12 h after the operation and does not increase the postoperative complications. Study [38] - [40] demonstrated that 4 h after surgery can effectively relieve the discomfort during bed rest without increasing vascular related complications. Foreign patients with arrhythmia began to change their position during and after radiofrequency ablation, and the earliest time to get out of bed was 4 h after surgery [41] [42] . Lee’s [43] studies have shown that intraoperative elevation of the head of the bed by 25˚ and hand massage can relieve postoperative back pain and promote comfort. Combining the above research conclusions, after femoral vein radiofrequency ablation, the head of the bed can be raised immediately after returning to the ward, and the decubitus position can be changed thereafter. According to the patient’s condition, she can get out of bed 4 to 6 h after the operation.

After pacemaker implantation, patients are routinely required to stay bedridden for 1 - 3 d in order to avoid complications such as electrode dislocation [44] , however, long bed rest can lead to back pain, constipation and other discomfort. Two Mate analyses [45] [46] showed that after fixing the surgical shoulder joint, the patient can get out of bed in 3 - 24 h, which can promote the patient’s comfort and ensure the safety and early rehabilitation. The study of Li et al. [47] showed that the patient was changed from the supine position to the semi-lying position 2 h after surgery, and the sitting position was 4 h. The early activity intervention could effectively reduce the related discomfort symptoms and improve the comfort and satisfaction of patients in rehabilitation. The study of Yuan [48] showed that 6 h mobilization could improve patient comfort without increasing the risk of postoperative bleeding and electrode dislocation. Wan et al. [49] study showed that the semi-lying position at 12 h and 24 h could effectively improve their shoulder joint function and improve their quality of life. Liu et al. [50] study showed that the head of the bed after the position, and the left and right side position, the sitting position and the bed after 8 h, which could promote the physical and mental comfort after surgery without increasing the postoperative complications. Zhang et al. [51] studies have shown that assisting in the sitting position and gradually leaving the bed after 6 h after surgery, which can effectively reduce postoperative back pain, urinary retention, shorten hospital stay and increase patient comfort. Budano [52] and Miracapillo [53] also showed that early mobilization after 3 h was safe and feasible compared with standard 24 h, independent of an increased risk of intraoperative complications. It can be seen that the shoulder joint after pacemaker surgery can prevent the pacemaker electrode dislocation, so the position can be changed early to reduce the related discomfort symptoms. Considering all the above studies, the semi-lying and sitting positions were taken 4 h after pacemaker implantation, and moved after 6 - 12 h.

Over the years, advances in medical technology have allowed more than 90 percent of children with congenital heart disease (CHD) to live to adulthood, the number of adults with congenital heart disease (ACHD), and the number of transcatheter interventions [54] . A Meta-analysis showed that implementing exercise rehabilitation training has positive significance for children with congenital heart disease, which can improve the quality of life and shorten the hospital stay [55] . However, the timing and content of the specific postoperative rehabilitation exercise were not explained. According to the consensus of standardized diagnosis and treatment of patent foramen ovale, Chinese experts stayed in bed for 12 h after occlusion [56] . Qin et al. [57] study showed that after occlusion of patent foramen ovale, no nausea and vomiting can raise the bed 30˚ after 2 h, relieve compression at 6 h, get out of bed for 12 h, and at 2 h after straight raise the lower limbs 20˚ to 30˚, and appropriately turn on the side. Compared with conventional puncture site compression for 12 h, supine and braking for 24 h, it can improve anxiety and depression, stabilize blood pressure and heart rate, and reduce postoperative complications. Different types of surgery for congenital heart disease lead to different operation time. In order to ensure the safety after surgery, the bed time is longer than other types of surgery. Therefore, 2 h after congenital heart disease intervention can raise the head of the bed, gradually bed activity, 12 h later can get out of bed activity.

The cardiac interventional puncture requires not only effective compression and hemostasis, but also surgical limb brake, and absolute bed rest if necessary. Most of the patients during the bed back pain, anxiety and urination difficulties many discomfort. Wang et al. [58] study found that early standardized activities can improve the left ventricular ejection fraction and 6 min walking test distance after PCI, and improve the quality of life. There is a study [24] suggesting that ambulation 2 - 3 h after removal of the sheath after femoral vein intervention reduced back pain and urinary tract symptom discomfort, and the incidence of vascular-related complications was unchanged. Cha et al. [28] study showed that early positioning changes can significantly improve lower back pain during bed rest after coronary intervention. Meanwhile, the study of Valiee et al. [29] also showed that the early positioning changes after angiography can reduce the symptoms of groin pain, back pain, urinary retention, and increase patient comfort. Liang et al. [30] study showed that early ambulation programs can effectively and safely increase comfort and reduce coronary intervention levels of lower back pain without increasing vascular-related complications. Haghshenas’s study [42] has shown that an early ambulation regimen can be effective in increasing postoperative comfort and relieving low-back pain levels without changes in the incidence of vascular complications. There is also a study [36] showed that early positioning intervention and ambulation can reduce the incidence of physical discomfort caused by braking and being bedridden after radiofrequency ablation in patients with atrial fibrillation, reduce patient anxiety, improve the comfort of postoperative patients, and will not increase the incidence of bleeding and hematoma at the puncture site.

Therefore, it seems that early activity has a positive effect in reducing related postoperative complications after cardiovascular intervention, and most studies show that early activity does not increase related complications after interventional surgery. However, most of the studies have focused only on the effect of the wish during hospitalization after the activity, and no follow-up and research on out-of-hospital and long-term effects. Therefore, subsequent studies can further explore the impact of early postoperative activity on long-term cardiac rehabilitation therapy.

Early activity can bring great economic benefits. Early activity of patients in neurological intensive care units reduces health care costs by 15% to 30%, the main reason may be that early activity can reduce the incidence of complications, shorten the length of hospital stay and reduce the readmission rate of patients [59] . Yue et al. [60] study showed thatApply early cardiac rehabilitation care to acute myocardial infarction Dead interventional surgery, the average length of stay can be reduced by 2 days. At the same time, Wan et al. [49] the study concluded that early cardiac rehabilitation intervention in the experimental group could reduce the complication rate by 15% relative to the control group after pacemaker implantation. There is also research [51] [61] studies that showed that early postoperative pacemaker mobilization can reduce postoperative complications and shorten hospital stay. Thus, early activity reduces the complications after cardiac intervention, shortens the hospital stay and saves medical costs to a large extent.

Although early mobilization has become a major element of postoperative care, early mobilization interventions for heart-related surgery are in a developmental stage [62] , there is no consensus at home and abroad on the starting time and content of the early postoperative activities [6] . As a result, health care workers have some concerns about their early activity programmes. As an important part of cardiac rehabilitation, the early activity of cardiac rehabilitation personnel lacks a training and access system in China, which leads to some doctors and nurses’ lack of understanding and attention to the theory and practice of cardiac rehabilitation [5] . Therefore, medical personnel need to deepen the training of early postoperative activities and cardiac rehabilitation theory knowledge, and spread the concept of early rehabilitation to patients and their families in the course of medical activities.

The degree of knowledge of cardiac rehabilitation directly affects the participation rate and compliance of cardiac rehabilitation [63] . The traditional thinking is that patients should rest and rest more after surgery [64] . At the same time, the fear of wound bleeding so that the patient is afraid to move after surgery. It can be seen that patients’ lack of knowledge of cardiac rehabilitation and insufficient understanding of early activities lead to the resistance to early activities after interventional surgery. Medical staff can learn the relevant knowledge and gradually participate through health education videos, manuals and bedside displays.
