A qualitative approach was used to explore and obtain a deeper understanding of the experiences of patients after cardiac surgery. Based on the results, life after cardiac surgery is seen as a dynamic experience, characterized by periods of certainty, uncertainty, and changes in behavior and feelings that evolve over time. The patients described a high level of limitations after cardiac surgery. The findings showed that struggling to live with their limitations was a common theme in all of the categories. Restrictions can destroy an individual’s sense of control of their life (
20). The illness and hospital treatment of CAD both represent serious challenges to the patient. These challenges are likely to stimulate a range of problem-focused (i.e. seeking help, information, and social support, and initiating life style changes) as well as emotion-focused strategies (i.e. strategies for managing the fear and anxiety associated with the illness, treatment and the hospital setting) (
12). The results of Shojaei’s study demonstrate the impact of heart disease on all aspects of patients’ life (
21). The lived experiences of patients after heart operations as narrated by the informants in this study can be understood within the following themes: concern of going out therapeutic framework, Tired of living within the confines of the therapeutic framework and living between boundaries. Within the first theme, the patients’ experiences represent the concern of going out therapeutic framework. The fear of the recurrence of a heart attack, the fear of doing more activities than permitted, the fear of taking journeys and the fear of mass communication were experienced by patients. Exploring the patients’ lives led us to the fact that a huge part of the patients’ fears were due to changes that had happened after cardiac surgery. Having a heart attack had had a profound impact on the patients in many ways (
8). In this study, patients spoke of their fear of having a heart attack again with going out therapeutic framework. These findings were confirmed by the patients in White’s study, who expressed considerable fear and anxiety that they might have another (fatal or severely debilitating) acute event at any time, especially that it might be fatal. Moreover, this is often coupled with sadness or depression over the loss of their previous good health, which may remain for months afterwards (
8). Since occasional chest pains are reported as a reason for fear and anxiety, and anxiety is a factor known to negatively influence recovery after a cardiac event (
22), patient pain could be reduced with suitable treatments. Although there is no consensus on the mechanisms underlying CPOP (Chronic Postoperative Pain), knowledge of predictors for increased risk of CPOP should be integrated into health care professionals’ pain assessments of CABG patients. Treating acute pain and analgesic medications are needed after cardiac surgery (
23). Few patients did not talk about their fears, although this did not necessarily mean that they were not worried about having another heart attack.
Fear of doing more activities than permitted was another concern for patients. Similarly, in Namazy’s study, patients were sick after surgery, felt sicker than before, and their activities were limited (
9). In another study, patients spoke of the “fear in the back of their mind that they were frightened of doing something that will bring it on again” (
8). In Lie et al.’s study, patients used to a high level of physical activity prior to surgery systematically increased their activity after surgery even if they felt it was tough (
10). Perhaps cultural differences and adequate knowledge of the scope of activity are reasons for the difference.
Fear of taking journeys was another finding of the present study. Some patients’ concern of cardiac attacks during journeys can lead to them avoiding going on journeys. The most prominent impacts of cardiac disease on a person’s everyday life have been identified as social isolation and living in fear (
24). Hazelton wrote: “Many patients withdraw from social or physical activities, often under the conception that they are helping themselves” (
25). The results of this study reflect the patient's inability to comply with the condition and to return to life before the illness. The ability to cope with a crisis, such as a disease, depends to a great extent on factors, such as support from family and friends, and advice from health-care professionals, to feeling appreciated and loved (
26). In this respect, the perceived support and information from family and staff are very effective. Family support is considered crucial to regaining health as soon as possible and changes the life of the patient after a heart attack (
27).
Fear of mass communication was experienced by patients in this study. Lack of good sleep and chest pain were the main causes of fear of mass communication. Similarly, tiredness or fatigue, such as the need to rest or sleep during the daytime, and difficulties with sleep patterns were reported as problems, as were falling asleep or waking up too early, in Lie et al.’s study (
10). Furthermore, the main findings of Schou and Egerod’s results relate to general phenomena such as discomfort and impaired communication (
28). Since fear and concern have different meanings depending on the individual, as these are experienced differently from person to person, even appropriate information delivered can be used to plan appropriate on need of patient by health care professionals.
The second theme that was extracted based on the experiences of patients was being tired of living within the confines of the therapeutic framework. Taking Medications Multiple Times, dietary restrictions, limitations and family fatigue, were the most common issues mentioned by the patients. Similar results have been obtained in other studies.
5.1. Taking Medications Multiple Times
Excessive use of drugs led to patients experiencing fatigue and not adhering to their medication regimen. Some studies showed that patients with cardiovascular disease are known to adhere poorly to medication (
29). Based on the findings of a qualitative research study, it was shown that patients perceived medicines as an “intrusion into their daily life”, were concerned about having to take them for the rest of their lives, and that some patients disliked taking medicines (
8). Some of the participants spoke of a lack of awareness of the need to take medicine. In line with these findings, Tolmie and colleagues found that some patients were not taking their medicines and that one of the reasons for this was that they were not convinced that their diagnosis was accurate or that the medication was necessary (
30). Similarly, 35% of the patients in Lie et al.’s study did not know why they had to take the prescribed medication (
10). In addition to the above, Shafipour et al. reported that all the patients in their study requested the necessary information and education about how to use food and their medicine (
13). The results from this study indicate a need for an improvement in information, education and individualized advice and, also, for there to be a way for the patient to ask questions that is very straightforward.
Being tired of dietary restrictions was one of the subthemes of this study and it seemed that insufficient information was aggravating this issue. A similar result was obtained in Sabzmakan et al.’s study. In this study, conflicts between patients’ diet regimens and their families’ diet regimens, and the patients becoming tired of the taste of their diet regimens were perceived as barriers to behavioral change in patients (
31). Furthermore, a lack of information after CABG (
10) and at discharge was reported in other studies (
10, 32). Inadequate provision of appropriate information may be a particular problem for certain groups of patients (
33, 34). Several studies have claimed that patients have unmet information needs after discharge, following acute myocardial infarctions (AMI). One major theme in a study was informational needs being unmet (needing more or different information) (
7). For example, studies have found that patients were aware that they needed to reduce their fat intake but they were often not sure about exactly what they should be eating (
8). Since there is a link between understanding the positive effects of a behavior and following the behavior (
35), improving patients’ understanding of dietary restrictions is essential for positive behavior.
After heart surgery, patients experienced limitations to their functions, including limitations to physical, psychological and social functions. The illness disturbs the body’s access to the world and prevents the person from carrying out their natural daily life (
15). Feeling tired and having no energy during the day, and being unable to handle daily living activities like taking a bath, buttoning up clothes and walking, were expressed by patients posteratively in Namazi’s (
9) study. Heart disease and heart surgery as a life event is naturally experienced as a threat to life (
36), and accompanied by physical and psychological changes in patients (
20). More attention is necessary in CABG patients who are manual workers and who feel insecure about the future. This occupation is an independent predictor for patients’ failure to return to work after CABG (
10). Some patients report pain, fatigue and sleep disturbances as prevalent symptoms during the first weeks after CABG (
37) and, in Namazi’s study, spoke of strong and rapid heartbeats in the first few weeks after the operation as inhibiting their engagement in normal daily activities (
9). Banner wrote: “Unsuccessful patients frequently talked about how their inability to engage in physical activity was … the result of limitations related to coronary disease” (
38). Patients had different experiences with physical activity, thus, patients should be assessed individually and their education should be planned based on their needs. Patients experienced psychological limitations. Similarly, the main findings in Schou and Egerod’s study relate to general phenomena, such as psychological phenomena, such as loss of control and loneliness, and existential phenomena, such as temporality and difficulties in human interactions (
28). In a qualitative study, participants expressed losing control, inability to handle stress, and being disturbed by a single small stimulus (
9).
Patients also experienced limitations to their social functions. Similarly, in another study, patients were worried about the possibility of not maintaining their previous role and level of responsibility in their family and in society (
13). In White’s study, patients revealed that after discharge, they had not been able to do anything, even small jobs, and were easily tired (
8). Furthermore, in Pourghane et al.’s study, patients spoke of the reduction of individual roles and activities due to the problems of heart disease (
39). Various psychosocial factors have been associated with RTW (Return to Work), including negative emotions and illness related cognitions. Review studies have concluded that psychological factors are the most important and are decisive factors associated with RTW after a cardiac event (
12).
Participants were concerned about their family’s fatigue in the treatment process. It was clear that having a heart patient in the family would have a broad impact on the family. The family of the patient is also affected by this crisis (
9). The patient may recover more slowly or have trouble resuming the activities of daily living (ADL) (
40) and, in this process, family vulnerability is not unexpected. Participants in Dabirian et al.’s study reported having encountered family problems for a few months after surgery (
41). In this study, some patients could not adequately explain their concerns. It seemed some had a tendency to not express their concerns, which is consistent with Shafipour et al. and Karlsson et al.’s studies (
13, 42). Living between boundaries was the third theme extracted based on the experiences of patients. Patients found themselves at the boundary between knowing or not knowing, feeling caught between wanting to accept or reject their treatment, and satisfaction or dissatisfaction that heart disease is curable.
Severe illnesses often lead to a crisis. A crisis means a feeling of distance, confusion, and a loss of control and a loss of ability to handle the situation (
42). In this study, patients lost a lot of confidence. The incidence of such cases can cause patients not to seek follow-up treatment. Thus, if the care of the patient is to be continued after they are discharged and go home, it is essential that they receive a good care plan from their health care providers and receive proactive support from both nurses and their family; these can have a valuable and assuring influence on patients. In Rakhshan et al.’s qualitative study, “Hesitation in accepting life with a pacemaker” was one of the subthemes identified (
20). Berghammer et al. have claimed that patients had to strike a balance between being different and not being different; being sick and being healthy (
40). These patients faced delays in their recovery, and they need emotional and practical advice from expert health care professionals (
7). Repeatedly telling patients that they need further treatment and methods of care is not enough, and may cause patients to feel a reduced sense of wellbeing and a feeling of loss of personal control over their health (
43), and trust in their efficiency and ability to perform self-care. Depending on the implementation of the desired behavior (
31,
44), health experts can emphasize the patient’s ability and efficiency.
The findings of this study give us an in-depth and more detailed understanding of the lived experiences of patients after cardiac surgery. Knowledge of patients’ needs may provide direction for clinical practice. The results can be used by health care providers to create a supportive environment that promotes a better quality of life for cardiac patients. The strength of the study is that the interviews were conducted by a researcher (the first author) to promote consistency in interviewing. The forgetfulness or unwillingness of some patients to completely recount their experiences can be considered as the limitations of this qualitative study.
This study revealed patients’ experiences after cardiac surgery. Based on the results of the study, we see that patients need information and support to resume their routine lives after cardiac surgery. The study’s results will be useful for medical teams seeking to relate to what patients experienced as limitations and how health teams can devise strategies for health promotion and to improve the patients’ quality of life after surgery. Further research is needed to better understand the complications that will occur after cardiac surgery and in the follow-up to produce better outcomes. This study focused on the patients’ perspectives after cardiac surgery in the Guilan province of Iran. Therefore, conducting further studies in different cultures and contexts is suggested in order to substantiate and follow up on this study’s findings, as well as to improve awareness among health teams regarding the different aspects of patients’ experiences after cardiac surgery.
