Clinical significance of mirror lesions in lower extremity arterial disease.

OBJECTIVE: The aim of this study was to investigate the clinical relevance of bilateral peripheral arterial disease (PAD) patterns. BACKGROUND: No prior study has evaluated the clinical significance of symmetrical lesion patterns, particularly the coexistence of same-level significant plaques in both lower extremities ("mirror lesions"). METHODS: We conducted a single-facility, primary data analysis involving 225 patients with symptomatic PAD. RESULTS: Eighty-two percent of the patients had bilateral lesions: 14.2% had femoropopliteal, 38.7% had infrapopliteal, and 27.1% had both femoropopliteal and infrapopliteal lesions. The lesions were found in the exact same arteries bilaterally in 24.9% of the patients, while 26.7% had a local mirror pattern limited to the femoropopliteal (13.7%) or infrapopliteal (12.9%) arteries. Having a lesion in an artery was a risk factor for occlusive disease of the corresponding artery on the other side. Patients presenting with critical limb ischemia (CLI) had a history of resting pain (17%), ulceration/gangrene (13%), or prior amputation (26%) of the contralateral limb. Patients with significant bilateral disease had unilateral false-negative ABI results in 11.6% of the cases. The arterial Doppler study results were unilaterally false-negative in 19.6% and bilaterally false-negative in 2.8% of the patients. CONCLUSIONS: Patients with known peripheral arterial disease need to have both limbs fully evaluated and monitored, even in cases with negative screening results. Mirror angiographic imaging is common and often accompanied by symptoms of claudication. Unilateral ischemia is a strong risk factor for contralateral disease. Patients with CLI are at high risk for occlusive lesions of the nonindex limb.

Evaluation of the level of depression among medical students from Poland, Portugal and Germany.

BACKGROUND: Depression is a serious illness affecting health, family and professional life of many people of all sectors of society. It also concerns students, regardless of their geographical location. The Beck Depression Inventory (BDI) is a proper tool to brief check of the level of depression because it has high correlation with depression. The aim of this study was to assess and compare the level of depression among medical students from Poland, Portugal and Germany. SUBJECTS AND METHODS: Students from different countries were asked to fill in an electronic form containing the BDI. The form was created separately for each country, using official translation of the BDI, approved by the competent psychiatric association. Google Drive software was used for the electronic form, and Stat soft Statistica v10 software for statistical analysis. RESULTS: There were statistically significant differences (p<0.05) in terms of average score of the BDI and of the proportion of the scores more than 10 points of medical and technology students among kinds of studies and countries. The average score of the BDI of medical students: Poland: 13.76±9.99 points; Germany: 8.49±7.64 points; Portugal: 7.37±7.67 points. The average score of the BDI of technology students: Poland: 12.42±9.66 points; Germany: 10.51±8.49 points; Portugal: 9.25±8.97 points. The proportion of the scores more than 10 points of medical students: Poland 56.32% (285/506) Germany 34.92% (154/441) Portugal 26.03% (82/315). The proportion of the scores more than 10 points of technology students: Poland 55.01% (368/669) Germany 43.82% (156/356) Portugal 37.57% (136/362). CONCLUSIONS: The highest depression score among medical and technology students according the BDI was found in Poland. A proper monitoring of depression is required, as well as rapid and appropriate help for those who suffer from it.

Long-term outcomes of the Coordinated Care Program in Patients after Myocardial Infarction (KOS-MI).

BACKGROUND: The Coordinated Care in Myocardial Infarction Program (KOS-MI) was introduced to improve prognosis for patients after myocardial infarction (MI). The program includes complete revascularization followed by unrestricted access to rehabilitation, electrotherapy and cardiac care. AIM: The aim of this study was to assess major adverse cardiac and cerebrovascular events (MACCE) of patients enrolled in the KOS-MI at 3-year follow-up. METHODS: This is a retrospective, multicenter registry of patients treated for MI. Study group (KOS-MI) of 963 patients was compared to the control group (standard of care) of 1009 patients. At 3-year follow-up MACCE including death, MI, stroke and repeated revascularization were reported. Additionally, hospitalization due to heart failure (HF) was analyzed. Propensity score matching (PSM) was utilized for group baseline characteristics adjustment. RESULTS: Patients in the KOS-MI group were younger (65 vs. 68; P < 0.001), mostly men (70% vs. 62.9%; P < 0.001), admitted with ST-elevation myocardial infarction (STEMI) (44.6% vs. 36.2%; P < 0.001). Patients in the control group had more comorbidities and were admitted more often with non ST-elevation myocardial infarction (63.8% vs. 55.4%; P < 0.001) and acute HF (5.1% vs. 2.7%; P = 0.007). Following PSM 530 well matched pairs were selected. At three years (92.3% follow-up completeness), the relative risk reduction was: 25% in MACCE (P = 0.008), 38% in mortality (P = 0.008), 29% in repeated revascularization(P = 0.04) and 28% (P = 0.0496) in hospitalization for HF in the KOS-MI group. CONCLUSIONS: The combination of contemporary invasive techniques, complete revascularization, cardiac rehabilitation and ambulatory care included in the KOS-MI Program improves long-term prognosis of patients after MI up to 3-year follow-up.

Actual status and future directions of cardiac telerehabilitation.

Telerehabilitation (TR) was developed to achieve the same results as would be achieved by the standard rehabilitation process and to overcome potential geographical barriers and staff deficiencies. This is especially relevant in periodic crisis situations, including the recent COVID-19 pandemic. Proper execution of TR strategy requires both well-educated staff and dedicated equipment. Various studies have shown that TR may have similar effects to traditional rehabilitation in terms of clinical outcomes and may also reduce total healthcare costs per participant, including rehospitalization costs. However, as with any method, TR has its advantages and disadvantages, including a lack of direct contact or prerequisite, rudimentary ability of the patients to handle mobile devices, among other competencies. Herein, is a discussion of the current status of TR, focusing primarily on cardiac TR, describing some technical/organizational and legal aspects, highlighting the indications, examining cost-effectiveness, as well as outlining possible future directions.

Aborted myocardial infarction in patients with ST-segment elevation myocardial infarction treated with mechanical reperfusion.

BACKGROUND: Aborted myocardial infarction (abMI) is a type of acute coronary syndrome in which patients treated with reperfusion avoid the great burden of necrosis. Yet, no definition of abMI in patients undergoing primary percutaneous coronary intervention (pPCI) has been proposed so far. AIMS: This study aimed to identify patients with abMI and compare them with the remaining patients with ST­segment elevation myocardial infarction (STEMI). METHODS: It was a retrospective study of 1693 consecutive patients with STEMI treated with pPCI. The median (IQR) follow­up was 3.45 (1.45-5.09) years. Aborted MI was diagnosed if ST­segment elevation was reduced by more than 50%, no new abnormal Q waves were observed, the maximal level of creatine kinase MB did not reach a value 5­fold higher than the upper limit of normal (below 125 U/l), and there was successful reperfusion defined as the Thrombolysis in Myocardial Infarction score of 3 after PCI. RESULTS: Using our definition, abMI was diagnosed in 176 cases (10.4%). Compared with the remaining patients with STEMI, those with abMI were younger (mean [SD] age, 61.8 [11.5] vs 64.4 [11.6] years; P = 0.005) and were more frequent smokers (48.9% vs 36.7%; P = 0.002). They had greater left ventricular ejection fraction (median [interquartile range (IQR)], 49% [40%-55%] vs 55% [51%-60.5%]; P <0.001), were discharged earlier from the hospital (hospitalization time, median [IQR], 73 [60-90.5] hours vs 87 [69-98] hours; P <0.001), and had a lower mortality rate at 1 month and long­term follow­up (2.27% vs 8%; P = 0.006 and 10.8% vs 23.9%; P <0.001, respectively). CONCLUSION: Patients with abMI had better short­ and long­term outcomes than other patients with STEMI. Some negative cardiovascular factors such as smoking were more often observed in the abMI group.

Comparison of long-term outcomes after directional versus rotational atherectomy in peripheral artery disease.

INTRODUCTION: The rate of atherectomy utilization in peripheral artery diseases (PAD) is growing. The two atherectomy devices available on the market and used most frequently are the directional and rotational ones. Nonetheless, there is a lack of direct comparison between these two types of atherectomy in PAD. AIM: To compare the long-term outcomes after PAD endovascular revascularization with two types of atherectomies: rotational (AR) (Phoenix Philips) and directional (AD) (SilverHawk Medtronic). MATERIAL AND METHODS: This was a single-center, retrospective study of obstructive and symptomatic PAD patients who underwent revascularization with atherectomy. The endpoints were considered as target lesion revascularization (TLR), death, amputations and bailout stenting (BS). RESULTS: The AR group consisted of 97 patients, while the AD group consisted of 85 individuals. There were no significant differences between the groups in terms of baseline characteristics except for an increased critical limb ischemia (CLI) prevalence in the AR group. The mean follow-up for AD and AR was 282.6 ±147.4 and 255.7 ±186.1 days, respectively (p = 0.44). There were no significant differences in the death rate (AD: 1 (1.7%) vs. AR: 5 (5.7%); p = 0.54), amputations (AD: 2 (2.3%) vs. AR: 5 (5.7%); p = 0.45) or bailout stenting (AD: 2 (2.3%) vs. AR: 3 (3.2%); p = 0.74), whereas TLR was more frequent in the AD group (AD: 25 (29%) vs. AR: 15 (15.9%; p = 0.03). The Kaplan-Meier analysis showed no significant differences between the groups in time to TLR, amputation or death. CONCLUSIONS: In this hypothesis-generating study the AR had a lower rate of TLR when compared to the AD. Nevertheless, this should be confirmed in further controlled randomized trials.

Long term outcomes in diabetic patients treated with atherectomy for peripheral artery disease.

BACKGROUND: The prevalence of diabetes has increased significantly in well-developed countries during the last decade and it continues to grow. Diabetes increases the risk of restenosis in patients treated percutaneously for peripheral artery disease. The present study sought to compare outcomes of atherectomy treatment in diabetic (DM) vs. non-diabetic (nDM) patients suffering from peripheral artery disease. METHOD: Between 2008 and 2012, 204 revascularization atherectomy procedures were performed on arteries of the lower extremities. The endpoints included target lesion revascularization (TLR), amputation and death. The type of atherectomy (excisional-soft plaque, orbital-calcified plaque, with active aspiration - with a thrombus) was left to operator discretion. RESULTS: This study contains 132 DM (66% male, age 68 ± 11.2 years) and 72 nDM (63% male, age 75 ± 11.3 years) subjects. DM were younger but had a higher prevalence of coronary artery disease (DM: 91% vs. nDM: 62%, p < 0.0001) and end-stage renal disease (DM: 22% vs. nDM: 2.5%, p < 0.0001). There were no differences in critical limb ischemia between the groups (DM: 21% vs. nDM: 12%, p = = 0.13). Mean time of follow-up was 384 and 411 days in DM and nDM, respectively (p = 0.43). There were no significant differences in TLR (DM: 15.2% vs. nDM: 22.2%, p = 0.249), amputations (DM: 3.0% vs. nDM: 1.5%, p = NS) or death rates (DM: 2.2% vs. nDM: 2.7%, p = NS). Kaplan-Mayer analysis showed no significant differences between the groups in the time to TLR, amputation or death. CONCLUSIONS: Plaque modification with adjusted atherectomy appears to have similar outcomes in diabetic as well as in non-diabetic patients. Nonetheless, a randomized study would be warranted to confirm the findings of the current study.
