Advances in Technology Promote Patient-Centered Care in Cardiac Rehabilitation.

Patient-centered health care (PCC) is a framework of clinical care focused on the patient's individual health care needs. In particular, it emphasizes the development of a partnership between the patient, physician, and healthcare workers to actively involve and empower the patient in their health care decisions. Additionally, PCC goals include ensuring access to care, emotional support, engaging patient support systems, physical comfort, and continuity of care. Technology also provides a platform to engage patients and their families in their care and can be a useful tool to gauge their level of interest, knowledge, and motivations to adequately educate them on the many factors that contribute to their disease, including diet, exercise, medication adherence, psychological support, and early symptom detection. In this article, we summarize the importance of technology in promoting PCC in cardiac rehabilitation and the impact technology may have on the different aspects of patient and physician relationships. Modern technological devices including smartphones, tablets, wearables, and other internet-enabled devices have been shown to help patient-staff communication, cater to patients' individual needs, increase access to health care, and implement aspects of PCC domains.

The Effects of Preoperative Pain Education on Pain Severity in Cardiac Surgery Patients: A Pilot Randomized Control Trial.

BACKGROUND: There is minimal research on the effect of individualized preoperative education on postoperative pain and postoperative pain medication intake. AIM: The study objective was to assess the effect of individually tailored preoperative education on postoperative pain severity, number of pain breakthroughs, and use of pain medication in participants receiving the intervention compared to controls. METHODS: A pilot study with 200 participants was conducted. The experimental group received an informational booklet and discussed their ideas surrounding pain and pain medication with the researcher. Controls received no intervention. Postoperative pain severity was measured by a Numerical Rating System (NRS), which was divided into mild (NRS 1-3), moderate (NRS 4-6), and severe (NRS 7-10). RESULTS: In the participant cohort, 68.8% of participants were male, and the average age was 60.48±10.7. Average postoperative 48-hour cumulative pain scores were lower in those who received the intervention compared to controls; 50.0 (IQR 35.8-60.0) vs. 65 (IQR 51.0-73.0; p < .01) participants who received the intervention had less frequent pain breakthroughs when compared to controls (3.0 [IQR 2.0-5.0] vs. 6.0 [IQR 4.0-8.0; p < .01]). There was no significant difference in the amount of pain medication taken by either group. CONCLUSIONS: Participants who receive individualized preoperative pain education are more likely to have decreased postoperative pain.

Relationships among norepinephrine levels, exercise capacity, and chronotropic responses in heart failure patients.

In heart failure (HF) patients, the pathophysiological mechanisms of severe exercise intolerance and impaired exercise capacity are related to both central and peripheral abnormalities. The central abnormalities in HF patients include impaired cardiac function and chronotropic incompetence (CI). Indeed, CI, the inability to adequately increase heart rate (HR) from rest to exercise often exhibited by HF patients, is related to activation of the sympathetic nervous system (SNS) yielding a rise in circulating norepinephrine (NE). CI may result from downregulation of ß-adrenergic receptors, ß-blocker usage, high baseline HR, or due to a combination of factors. This paper discusses the role of elevated NE in altering chronotropic responses in HF patients and consequently resulting in impaired exercise capacity. We suggest that future research should focus on the potential treatment of CI with rate-adaptive pacing, using a sensor to measure physical activity, without inducing deleterious hormonal activation of the sympathetic system.

Predictors of prolonged hospitalization in modified sternoplasty following postoperative mediastinitis.

BACKGROUND AND AIM: Deep sternal wound infection (DSWI) is a serious complication following cardiac surgery, and demands early intervention as any delay in diagnosis and management may lead to increased morbidity and mortality. DSWI is associated with increased length of hospitalization (LOH) and economic burden in this patient population. The aim of this study was to determine predictors for increased length of hospitalization in patients who underwent the Modified Sternoplasty technique for deep sternal wound infection following cardiac surgery. METHODS: A retrospective study was undertaken on data from patients who underwent the Modified Sternoplasty surgery for DSWI between September 2010 and January 2020. Patients' characteristics that were recorded included medical history, type of the original heart surgery, length of hospitalizations, and risk factors including hyperlipidemia, diabetes mellitus and hypertension, and morbidity and mortality rates following the Modified Sternoplasty. RESULTS: Sixty-eight patients underwent the Modified Sternoplasty surgery with an average length of hospitalization of 24.63 + 22.09 days. Multivariable analysis showed that only gender was considered a predictor of length of hospitalization when controlling for comorbidities, with average length of hospitalization longer for women than men (35.4 vs. 20.9, p = .04). CONCLUSION: The Modified Sternoplasty surgery is a novel surgical technique for managing DSWI complicated by sternal dehiscence with exposed heart and great vessels. Female gender was associated with increased length of hospitalization in our patient cohort, with average length of hospitalization for women almost twice that of males.

Clinical factors and pre-surgical depression scores predict pain intensity in cardiac surgery patients.

BACKGROUND: Severe pain is prevalent in cardiac surgery patients and can increase cardiac complications, morbidity and mortality. The objectives of the study were to assess perioperative pain intensity and to assess predictors of pain post-cardiac surgery, including clinical characteristics and depression. METHODS: A total of 98 cardiac surgery patients were included in the study. Pain intensity was assessed using a Numerical Rating System. Pain was measured one day pre-operatively and recorded daily from Post-operative Day 2 to Day 7. Clinical data were recorded and depression scores were assessed using the Center for Epidemiological Study of Depression (CES-D). RESULTS: Pain intensity increased significantly during hospitalization from pre-operative levels, surging at 2 days post-operatively. Predictors of high pain intensity were high pre-operative CES-D scores, female gender, cardiac function, smoking and high body mass index (BMI). Significantly higher pre-operative CES-D scores were found in patients with severe pain compared to patients with no pain to moderate pain (18.23 ± 1.80 vs 12.84 ± 1.22, p = 0.01 pre-operatively). Patients with severe pain (NRS 7-10) had significantly higher levels of white blood cells (WBC) compared to patients with no pain-moderate pain (NRS 0-6), (p = 0.01). However, CES-D scores were only weakly correlated maximum WBC levels perioperatively. CONCLUSION: Pain intensity significantly increased following surgery, and was associated with depressive symptoms, female sex, cardiac function, BMI, and smoking. These factors may serve as a basis for identification and intervention to help prevent the transition from acute pain to chronic pain.

The Modified Sternoplasty: A Novel Surgical Technique for Treating Mediastinitis.

Deep sternal wound infection (DSWI) is one of the most complex and devastating complications post cardiac surgery. We present here the modified sternoplasty, a novel surgical technique for treating DSWI post cardiac surgery. The modified sternoplasty includes debridement and sternal refixation via bilateral longitudinal stainless-steel wires that are placed parasternally along the ribs at the midclavicular or anterior axillary line, followed by six to eight horizontal stainless-steel wires that are anchored laterally and directly into the ribs. On top of that solid structure, wound reconstruction is performed by the use of bilateral pectoralis muscle flaps followed by subcutaneous tissue and skin closure. We reported mortality rates and length of hospitalization of patients who underwent the modified sternoplasty. In total, 68 patients underwent the modified sternoplasty. Two of these critically ill patients died (2.9%). The average length of hospitalization from the diagnosis of DSWI was 24.63 ± 22.09 days. The modified sternoplasty for treating DSWI is a more complex surgery compared with other conventional sternoplasty techniques. However, this technique was demonstrated to be more effective, having a lower rate of mortality, and having a length of hospitalization lower than or comparable to other techniques previously reported in the literature.

Potential Role of Insulin-Like Growth Factors in Myofascial Pain Syndrome: A Narrative Review.

ABSTRACT: Insulin-like growth factors have diverse functions in skeletal muscles by acting through multiple signaling pathways, including growth regulation and differentiation, anti-inflammation, and antioxidation. Insulin-like growth factors have anti-inflammatory effects and also play roles in nociceptive pathways, determining pain sensitivity, in addition to their protective role against ischemic injury in both the nervous system and skeletal muscle. In skeletal muscle, insulin-like growth factors maintain homeostasis, playing key roles in maintenance, accelerating muscle regeneration, and repair processes. As part of their maintenance role, increased levels of insulin-like growth factors may be required for the repair mechanisms after exercise. Although the role of insulin-like growth factors in myofascial pain syndrome is not completely understood, there is evidence from a recent study that insulin-like growth factor 2 levels in patients with myofascial pain syndrome are lower than those of healthy individuals and are associated with increased levels of inflammatory biomarkers. Importantly, higher insulin-like growth factor 2 levels are associated with increased pain severity in myofascial pain syndrome patients. This may suggest that too low or high insulin-like growth factor levels may contribute to musculoskeletal disorder process, whereas a midrange levels may optimize healing without contributing to pain hypersensitivity. Future studies are required to address the mechanisms of insulin-like growth factor 2 in myofascial pain syndrome and the optimal level as a therapeutic agent.
