Why is it Important to Assess and Treat Alexithymia in the Cardiologic Field? An Overview of the Literature.

Background: Alexithymia has been found to be associated with several somatic illnesses, such as cardiovascular, indicating that it might be a risk factor for early death in the long-term course of post-myocardial infarction. From the cardiology perspective, the aim was to collect current evidence about the relationship between alexithymia and somatic illness. Methods: The literature was synthesized and summarized in a narrative format. The literature search was carried out in PubMed. Pertinent studies published in the last 50 years written in English were included and organized by three main topics ("The relation between alexithymia and somatic illness from the cardiology perspective"; "How do assess alexithymia?"; "Treating alexithymia") to be discussed. Results: High alexithymia is a dimensional trait that affects around 10% of the general population and up to 55% of people with essential hypertension. Also, the link between alexithymia and cardiovascular activity has been pointed out. There are several validated tools to assess alexithymia, as well as treatment options. Conclusion: Knowledge about the main features of alexithymia, as well as its assessment and treatment, can promote a multifactorial approach to the primary, secondary, and tertiary prevention of cardiac diseases.

Non-invasive coronary flow velocity reserve assessment predicts adverse outcome in women with unstable angina without obstructive coronary artery stenosis.

Background: Evaluation of coronary flow velocity reserve (CFVR) is the physiological approach to assess the severity of coronary stenosis and microvascular dysfunction. Impaired CFVR occurs frequently in women with suspected or known coronary artery disease. The aim of this study was to assess the role of CFVR to predict long-term cardiovascular event rate in women with unstable angina (UA) without obstructive coronary artery stenosis. Methods: CFVR in left anterior descending coronary artery was assessed by adenosine transthoracic echocardiograhy in 161 women admitted at our Department with UA and without obstructive coronary artery disease. Results: During a mean FU of 32.5 ± 19.6 months, 53 cardiac events occurred: 6 nonfatal acute myocardial infarction, 22 UA, 7 coronary revascularization by percutaneous transluminal coronary angioplasty, 1 coronary bypass surgery, 3 ischemic stroke, and 8 episodes of congestive heart failure with preserved ejection fraction and 6 cardiac deaths. Using a ROC curve analysis, CFVR 2.14 was the best predictor of cardiac events and was considered as abnormal CFVR. Abnormal CFVR was associated with lower cardiac event-free survival (30 vs 80%, p < 0.0001). During FU, 70% of women with reduced CFVR had cardiac events whereas only 20% with normal CFVR (p = 0.0001). At multivariate Cox analysis, smoke habitus (p = 0.003), metabolic syndrome (p = 0.01), and CFVR (p < 0.0001) were significantly associated with cardiac events at FU. Conclusion: Noninvasive CFVR provides an independent predictor of cardiovascular prognosis information in women with UA without obstructive coronary artery disease whereas, impaired CFVR seems to be associated with higher CV events at FU.

Alexithymia for cardiologists: a clinical approach to the patient.

Alexithymia literally meaning 'no words for emotions' is a term used in mental health settings to describe people who have difficulties in identifying and verbalizing their emotional states. There is evidence in the literature that this personality trait may influence negatively the illness behavior when an acute coronary event occurs. In fact, people with high alexithymia are more likely to experience wrong appraisal and interpretation of symptoms, and because of their difficulty in describing feelings to others, they can be poor in reporting symptoms at the first consultation with a physician. This behavioral pattern (alexithymic) may put patients with acute myocardial infarction at higher risk for delayed medical care. Here, we aim to present an overview of alexithymia from the perspective of the clinical cardiologist, with a focus on the definition, clinical recognition, and potential impact on cardiovascular health.

Impact of intra-aortic balloon counterpulsation on all-cause mortality among patients with Takotsubo syndrome complicated by cardiogenic shock: results from the German-Italian-Spanish (GEIST) registry.

Aims: Takotsubo syndrome (TTS) is an acute and reversible left ventricular dysfunction and can be complicated by cardiogenic shock (CS). However, few data are available on optimal care in TTS complicated by CS. Aim of this study was to evaluate short- and long-term impact of intra-aortic balloon pumping (IABP) on mortality in this setting. Methods and results: In a multi-centre, international registry on TTS, 2248 consecutive patients were enrolled from 38 centres from Germany, Italy, and Spain. Of the 2248 patients, 212 (9.4%) experienced CS. Patients with CS had a higher prevalence of diabetes (27% vs. 19%), male sex (25% vs. 10%), and right ventricular involvement (10% vs. 5%) (P < 0.01 in all cases). Forty-three patients with CS (20% of 212) received IABP within 8 h (interquartile range 4-18) after admission. No differences in terms of age, gender, cardiovascular risk factors, and admission left ventricular ejection fraction were found among patients with and without IABP. There were no significant differences in terms of 30-day mortality (16% vs. 17%, P = 0.98), length of hospitalization (18.9 vs. 16.7 days, P = 0.51), and need of invasive ventilation (35% vs. 41%, P = 0.60) among two groups: 30-day survival was not significantly different even after propensity score adjustment (log-rank P = 0.73). At 42-month follow-up, overall mortality in patients with CS and TTS was 35%, not significantly different between patients receiving IABP and not (37% vs. 35%, P = 0.72). Conclusions: In a large multi-centre observational registry, the use of IABP was not associated with lower mortality rates at short- and long-term follow-up in patients with TTS and CS.

The impact of UEFA Euro 2020 football championship on Takotsubo Syndrome: Results of a multicenter national registry.

Objectives: The UEFA 2020 European Football Championship held in multiple cities across Europe from June 11 to July 11, 2021, was won by Italy, providing an opportunity to examine the relationship between emotional stress and the incidence of acute cardiovascular events (ACE). Methods and results: Cardiovascular hospitalizations in the Cardiac Care Units of 49 hospital networks in Italy were assessed by emergency physicians during the UEFA Euro 2020 Football Championship. We compared the events that occurred during matches involving Italy with events that occurred during the remaining days of the championship as the control period. ACE was assessed in 1,235 patients. ACE during the UEFA Euro 2020 Football Championship semifinal and final, the most stressful matches ended with penalties and victory of the Italian team, were assessed. A significant increase in the incidence of Takotsubo Syndrome (TTS) by a factor of 11.41 (1.6-495.1, P < 0.003), as compared with the control period, was demonstrated during the semifinal and final, whereas no differences were found in the incidence of ACS [IRR 0.93(0.74-1.18), P = 0.57]. No differences in the incidence of ACS [IRR 0.98 (0.87-1.11; P = 0.80)] or TTS [IRR 1.66(0.80-3.4), P = 0.14] were found in the entire period including all matches of the UEFA Euro 2020 compared to the control period. Conclusions: The data of this national registry demonstrated an association between the semifinal and final of UEFA Euro 2020 and TTS suggesting that it can be triggered by also positive emotions such as the victory in the European Football Championship finals.

Alexithymia is a determinant of early death in the long-term course of post-myocardial infarction.

Among people with ST-segment elevation myocardial infarction (STEMI), high alexithymia was associated with delay to hospital arrival. High alexithymia could be a determinant of early death in the long term after STEMI. People with STEMI who participated in a survey in 2011, was tested about the state of life in 2021. The sample was divided into two cohorts (cut-off: TAS-20≥61 in 2011). The relationship between possible death occurred and having high alexithymia was calculated by comparing the mortality after 10 years in the two cohorts through the Cox' proportional hazard model. Status in life was verified on 39.3% of the sample. No differences were found regarding age, sex, high alexithymia between individuals on whom it was possible to verify the state in life and in whose it was not. In 2021, among people having high alexithymia in 2011, a higher risk of early death was found (RR=5.75, CI 95% 1.116-29.637).

Surviving to Acute Myocardial Infarction: The Role of Psychological Factors and Alexithymia in Delayed Time to Searching Care: A Systematic Review.

The time from symptom onset to reperfusion is a critical determinant of myocardial salvage and clinical outcomes in patients with acute myocardial infarction (AMI). This time period could be delayed if people do not seek help promptly and/or if the health system is not efficient in responding quickly and attending to these individuals. The aim of this study was to identify psychological factors associated with pre-hospital delay (PHD) or patients' decisional delay (PDD) in people with an ongoing AMI. A search in PubMed/Medline from 1990 to 2021 with the keywords "pre-hospital delay" OR "prehospital delay" OR "patient delay" OR "decisional delay" OR "care seeking behavior" AND "psychological factors" OR "alexithymia" AND "myocardial infarction" was performed. Thirty-six studies were included, involving 10.389 patients. Wrong appraisal, interpretation and causal beliefs about symptoms, denial of the severity of the symptoms and high levels of alexithymia were found related to longer PHD or PDD. Alexithymia may be an overarching construct that explains the disparate findings of the studies exploring the role of psychological factors in PHD or PDD. Further studies are needed in order to analyse the role of alexithymia in patients with risk factors for AMI to prevent delay.

Non-invasive estimation of stroke volume during exercise from oxygen in heart failure patients.

AIMS: In heart failure, oxygen uptake and cardiac output measurements at peak and during exercise are important in defining heart failure severity and prognosis. Several cardiopulmonary exercise test-derived parameters have been proposed to estimate stroke volume during exercise, including the oxygen pulse (oxygen uptake/heart rate). Data comparing measured stroke volume and the oxygen pulse or stroke volume estimates from the oxygen pulse at different stages of exercise in a sizeable population of healthy individuals and heart failure patients are lacking. METHODS: We analysed 1007 subjects, including 500 healthy and 507 heart failure patients, who underwent cardiopulmonary exercise testing with stroke volume determination by the inert gas rebreathing technique. Stroke volume measurements were made at rest, submaximal (∼50% of exercise) and peak exercise. At each stage of exercise, stroke volume estimates were obtained considering measured haemoglobin at rest, predicted exercise-induced haemoconcentration and peripheral oxygen extraction according to heart failure severity. RESULTS: A strong relationship between oxygen pulse and measured stroke volume was observed in healthy and heart failure subjects at submaximal (R2 = 0.6437 and R2 = 0.6723, respectively), and peak exercise (R2 = 0.6614 and R2 = 0.5662) but not at rest. In healthy and heart failure subjects, agreement between estimated and measured stroke volume was observed at submaximal (-3 ± 37 and -11 ± 72 ml, respectively) and peak exercise (1 ± 31 and 6 ± 29 ml, respectively) but not at rest. CONCLUSION: In heart failure patients, stroke volume estimation and oxygen pulse during exercise represent stroke volume, albeit with a relevant individual data dispersion so that both can be used for population studies but cannot be reliably applied to a single subject. Accordingly, whenever needed stroke volume must be measured directly.

Heart applications of 4D flow.

Four-dimensional (4D) flow sequences are an innovative type of MR sequences based upon phase contrast (PC) sequences which are a type of application of Angio-MRI together with the Time of Flight (TOF) sequences and Contrast-Enhanced Magnetic Resonance Acquisition (CE-MRA). They share the basic principles of PC, but unlike PC sequences, 4D flow has velocity encoding along all three flow directions and three-dimensional (3D) anatomic coverage. They guarantee the analysis of flow with multiplanarity on a post-processing level, which is a unique feature among MR sequences. Furthermore, this technique provides a completely new level to the in vivo flow analysis as it allows measurements in never studied districts such as intracranial applications or some parts of the heart never studied with echo-color-doppler, which is its sonographic equivalent. Furthermore, this technique provides a completely new level to the in vivo flow analysis as it allows accurate measurement of the flows in different districts (e.g., intracranial, cardiac) that are usually studied with echo-color-doppler, which is its sonographic equivalent. Of note, the technique has proved to be affected by less inter and intra-observer variability in several application. 4D-flow basic principles, advantages, limitations, common pitfalls and artefacts are described. This review will outline the basis of the formation of PC image, the construction of a 4D-flow and the huge impact the technique is having on the cardiovascular non-invasive examination. It will be then studied how this technique has had a huge impact on cardiovascular examinations especially on a central heart level.

Assessment of the German and Italian Stress Cardiomyopathy Score for Risk Stratification for In-hospital Complications in Patients With Takotsubo Syndrome.

Importance: Takotsubo syndrome (TTS) is an acute, reversible heart failure syndrome featured by significant rates of in-hospital complications. There is a lack of data for risk stratification during hospitalization. Objective: To derive a simple clinical score for risk prediction of in-hospital complications among patients with TTS. Design, Setting, and Participants: In this prognostic study, 1007 consecutive patients were enrolled in the German and Italian Stress Cardiomyopathy (GEIST) registry from July 1, 2007, through December 31, 2017, and identified as the derivation cohort; 946 patients were enrolled in the Spanish Registry for Takotsubo Cardiomyopathy (RETAKO) as the external score validation. An admission risk score was developed using a stepwise multivariable regression analysis from 2 registries. Data analysis was performed from March 1, 2018, through July 31, 2018. Main Outcomes and Measures: In-hospital complications were defined as death, pulmonary edema, need for invasive ventilation, and cardiogenic shock. Four variables were identified as independent predictors of in-hospital complications and were used for the score: male sex, history of neurologic disorder, right ventricular involvement, and left ventricular ejection fraction (LVEF). Results: Of the 1007 patients enrolled in the GEIST registry, 107 (10.6%) were male, with mean (SD) age of 69.8 (11.4) years. Overall rate of in-hospital complications was 23.3% (235 of 1007) (death, 4.0%; pulmonary edema, 5.8%; invasive ventilation, 6.4%; and cardiogenic shock, 9.1%). The GEIST prognosis score was derived by providing 20 points each for male sex and history of neurologic disorders and 30 points for right ventricular involvement and then subtracting the value in percent of LVEF (decimal values between 0.15 and 0.70). Score accuracy on area under the receiver operating characteristic curve analysis was 0.71, with a negative predictive power of 87% with scores less than 20. External validation in the RETAKO population (124 [13.1%] male; mean [SD] age, 69.5 [14.9] years) revealed an area under the curve of 0.73 (P = .46 vs GEIST derivation cohort). Stratification into 3 risk groups (<20, 20-40, and >40 points) classified 316 patients (40.9%) as having low risk; 342 (44.3%) as having intermediate risk, and 114 (14.8%) as having high risk of complications. The observed in-hospital complication rates were 12.7% for low-risk patients, 23.4% for intermediate-risk patients, and 58.8% for high-risk patients (P < .001 for trend). After 2.6 years of follow-up, patients with in-hospital complications had significantly higher rates of mortality than those without complications (40% vs 10%, P = .01). Conclusions and Relevance: The GEIST prognostic score may be useful in early risk stratification for TTS. High-risk patients with TTS may require an intensive care unit stay, and low-risk patients with TTS could be discharged within a few days. In-hospital complications in patients with TTS may be associated with increased risk of long-term mortality.

Coronary flow reserve is related to the extension and transmurality of myocardial necrosis and predicts functional recovery after acute myocardial infarction.

BACKGROUND: Few studies have examined the effect of transmurality of myocardial necrosis on coronary microcirculation. The aim of this study was to examine the influence of cardiac magnetic resonance-derived (GE-MRI) structural determinants of coronary flow reserve (CFR) after anterior myocardial infarction (STEMI), and their predictive value on regional functional recovery. METHODS: Noninvasive CFR and GE-MRI were studied in 37 anterior STEMI patients after primary coronary angioplasty. The wall motion score index in the left descending anterior coronary artery territory (A-WMSI) was calculated at admission and follow-up (FU). Recovery of regional left ventricular (LV) function was defined as the difference in A-WMSI at admission and FU. The necrosis score index (NSI) and transmurality score index (TSI) by GE-MRI were calculated in the risk area. Baseline (BMR) and hyperemic (HMR) microvascular resistance, arteriolar resistance index (ARI), and coronary resistance reserve (CRR) were calculated at the Doppler echocardiography. RESULTS: Bivariate analysis indicated that the CPK and troponin I peak, heart rate, NSI, TSI, BMR, the ARI, and CRR were related to CFR. Multivariable analysis revealed that TSI was the only independent determinant of CFR. The CFR value of >2.27, identified as optimal by ROC analysis, was 77% specific and 73% sensitive with accuracy of 76% in identifying patients with functional recovery. CONCLUSIONS: Preservation of microvascular function after AMI is related to the extent of transmurality of myocardial necrosis, is an important factor influencing regional LV recovery, and can be monitored by noninvasive CFR.

Prognosis and first diagnostic ECG in STEMI patients referred to the emergency medical system for primary PCI.

BACKGROUND: Pathological Q waves (QWs) in the first ECG recorded at hospital admission has been found to correlate with myocardial damage and mortality in STEMI patients. We investigated the association between new QWs recorded in the pre-hospital setting and adverse outcome during the hospital stay. METHODS: A pre-hospital ECG was recorded in 248 patients with STEMI who underwent primary PCI. Patients were divided into two groups based on the presence (n = 44, QWs) or absence (n = 204, non-QWs) of new QWs. RESULTS: Patients with new QWs had a higher prevalence of anterior infarct, cardiogenic shock and a lower LV ejection fraction. In-hospital mortality was higher in patients with new QWs. The percentage of patients with new QWs increased progressively with increasing pain to ECG time. CONCLUSIONS: New QWs provide rapid prognostic information in the pre-hospital phase of STEMI by identifying patients at risk of adverse outcome during the hospital stay.

Takotsubo Syndrome is Associated with Mood Disorders and Antidepressants Use, not with Anxiety and Impairment of Quality of Life Due to the Psychiatric Disorder.

BACKGROUND: The aim was to study the association between mood and anxiety disorders and the Tako-Tsubo Syndrome (TTS) and to determine the role of antidepressants and the impairment of quality of life due the comorbid psychiatric disorder. METHODS: Case-control study: 19 consecutive patients (17 female) with TTS compared to 76 controls without TTS, were randomly selected from the database of a nationwide epidemiological study after matching (gender, age and residence) by controls. Psychiatric diagnoses were carried out according to the ICD-10 using semi-structured interview tools (ANTAS-SCID) administered by clinical staff. Quality of Life (Qol) was assessed by means of SF-12. RESULTS: Only Major Depressive Disorders (MDD) showed higher frequencies in cases with statistical significance difference (p=0.014) as well as at least one Mood Disorder Diagnosis [MDD or BD] (p=0.002). The lifetime prevalence of at least one anxiety disorder with no comorbid mood disorder did not show a higher frequency in cases (p=0.57).The score at SF-12 in the TTS group was similar to those of controls (p=0.71)In the TTS group, the score at SF-12 in people with one mood or anxiety diagnosis (N=7) was similar to those without mood or anxiety diagnosis (p=0.75). The use of antidepressants was higher in TTS group (15.79% vs 1.31%; p=0.030). CONCLUSION: The study shows an association between TTS with depressive disorders and antidepressants use and does not confirm the association with anxiety syndromes. The study suggests the need to investigate the possible interactions between antidepressants use and mood disorders in studies with appropriate design and sample size.

Feasibility, symptoms, adverse effects, and complications associated with noninvasive assessment of coronary flow velocity reserve in women with suspected or known coronary artery disease.

BACKGROUND: Microvascular coronary impairment, defined as reduced coronary flow reserve, represents the predominant etiologic mechanism of ischemia in women with chest pain and no obstructive coronary artery disease. Transthoracic echocardiography (TTE) is a noninvasive method for assessing coronary flow velocity reserve (CFVR) in the left anterior descending coronary artery (LAD). The purpose of this investigation was to define the safety profile, feasibility, adverse events, and rate of complications of the test in women with suspected CAD. METHODS: We evaluated CFVR in LAD with TTE during adenosine infusion in 1455 women aged 66.4±11.9 years. RESULTS: A complete CFVR study was achieved in 1429 pts (feasibility 98.2%), the test being performed also in the early phase of acute coronary syndrome and on obese patients. Minor symptoms or adverse effects occurred in 43.7% of patients not requiring test termination: hyperpnea (16.7%), flushing (9.4%), atypical chest pain (9.9%), headache (6.6%), minor arrhythmias (2.9%), chest pain with EKG changes (1.5%) were the symptoms reported. No major complications were observed. CONCLUSIONS: Noninvasive assessment of CFVR in LAD by TTE is a very feasible method with very low incidence of adverse events and complications in women with suspected or known CAD. It is safe and can be used when evaluating female patients with atherosclerotic LAD disease or with coronary microvascular impairment.

Alexithymia affects the time from symptom onset to calling the emergency system in STEMI patients referred for primary PCI.

BACKGROUND: STEMI programs have been found to reduce the time to reperfusion but do not address the time delay caused by patients. In this study we sought to assess whether and to what extent alexithymia, defined as the inability to recognize and describe somatic feelings appropriately, impacts on this delay. METHODS: Ninety-five STEMI patients referred by the Emergency Medical System (EMS) to our hospital for primary percutaneous coronary intervention were studied. The time from symptom onset to the EMS call (time to call) as well as the time from the EMS call to the first intervention that restored patency of the culprit vessel (system delay) and the total ischemic time was calculated in patients categorized into two groups according to the Toronto Alexithymia scale (TAS-20): patients with higher alexithymia scores (≥61), and patients with lower scores of alexithymia (<61). RESULTS: According to the TAS-20, we identified 27 patients as being alexithymic and 68 patients as not. The time to call and the total ischemic time were longer in alexithymic compared to non alexithymic patients (respectively, 159min vs 35min, and 258.5 vs 139 , p=0.001), while the system delay was similar in both groups. CONCLUSIONS: Alexithymia is one trait of the patient personality which appears to have negative implications in the setting of a STEMI network by interfering with prompt seeking of care. This information could help in guiding novel strategies to motivate patients to call EMS quickly and further shorten the total ischemic time.

Care quality monitoring of a ST-segment elevation myocardial infarction programme over a 5-year period.

AIMS: The aim of this study is to investigate the long-term impact of a prehospital ECG programme on treatment times for patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). METHODS: From January 2008 to December 2012, 213 STEMI patients transported by the Emergency Medical System (EMS) underwent primary PCI in our Hospital. The protocol included ECG tele-transmission, early activation of the cath lab and direct routing of the patient for primary PCI. Fifty-four patients referred by EMS in 2007, when ECG tele-transmission was unavailable, were used as controls. First diagnostic ECG-to-balloon time, door-to-balloon time and total ischemic time were collected for all patients. RESULTS: First diagnostic ECG-to-balloon time decreased from 125.5 min in 2007 to 104 min in the first year after implementation of the STEMI programme (2008). Successively, it declined to 81 min by the end of the study period (2012) (P < 0.0001). Door-to-balloon time decreased notably from 92.5 min in 2007 to 40.5 min by the end of the study period (p < 0.0001). Total ischemic time fell from 200 min in 2007 to 170 min in 2008 and it further declined to 163.5 min in 2012 (p < 0.042). CONCLUSIONS: We report progressive improvements in times to treatment over a 5-year period in a STEMI program for patients referred by the EMS. The importance of data collection and monitoring is highlighted by our results.

Admission hyperglycemia in acute myocardial infarction: possible role in unveiling patients with previously undiagnosed diabetes mellitus.

AIM: The aim of this study was to investigate the relationship between admission plasma glucose levels and abnormal glucose metabolism in patients with acute myocardial infarction (AMI) without a previous diagnosis of diabetes mellitus. METHODS: A total of 285 nondiabetic patients admitted with AMI were screened for glucometabolic disorders by using fasting glucose measurements during hospital stay or an oral glucose tolerance test on discharge. Patients diagnosed as having diabetes mellitus were followed-up for a mean of 60 ±â€Š33 months in order to confirm the diagnosis. RESULTS: There was a graded relationship between admission glucose levels and the prevalence of newly detected diabetes mellitus (group 1, <140 mg/dl: 12%; group 2, ≥140 < 200 mg/dl: 40%; group 3, ≥200 mg/dl: 70.3%; P < 0.0001). The admission glucose level of at least 144 mg/dl was the best predictor of newly detected diabetes mellitus during hospitalization (area under the curve 0.78, P = 0.0001). In multivariable analysis, patients with admission hyperglycemia had greater odds of having newly detected diabetes mellitus (odds ratio 6.6, 95% confidence interval 2.7-16.3, P = 0.0001). Diabetes mellitus was confirmed in the long-term follow-up in 78% of patients diagnosed as having diabetes mellitus during hospitalization. CONCLUSION: Our finding suggests a relationship between admission glucose and previously undetected diabetes mellitus in nondiabetic patients presenting AMI. Acute hyperglycemia may help to identify high-risk patients for diabetes mellitus, who should be screened initially for glucometabolic disorders, then closely monitored and appropriately treated to improve outcome.
