Resumen Antecedentes: El pronóstico de los pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) y antecedente de intervención coronaria percutánea (ICP) es incierto. Objetivos: Evaluar si la ICP previa en pacientes con IAMCEST incrementa el riesgo de eventos cardiovasculares mayores y si el flujo final epicárdico varía según la estrategia de reperfusión. Material y métodos: Subestudio de PHASE-MX, observacional, longitudinal y comparativo, de pacientes con IAMCEST reperfundidos en menos de 12 horas de iniciados los síntomas, divididos conforme el antecedente de ICP. El acaecimiento del criterio de valoración principal (muerte cardiovascular, reinfarto, insuficiencia cardíaca y choque cardiogénico) dentro de los 30 días se comparó con estimaciones de Kaplan-Meier, prueba de rangos logarítmicos y modelo de riesgos proporcionales de Cox. El flujo epicárdico final se evaluó con el sistema de clasificación del flujo TIMI después de la reperfusión. Resultados: Se incluyeron 935 pacientes, 85.6 % del sexo masculino, 6.9 % de los cuales tenía antecedente de ICP; 53 % recibió terapia farmacoinvasiva y 47 %, ICP primaria. La incidencia del criterio de valoración principal en pacientes con ICP previa fue de 9.8 % versus 13.3 % en aquellos sin ese antecedente (p = 0.06); 87.1 % de los pacientes con ICP previa obtuvo flujo final de grado TIMI 3 versus 75 % del grupo con estrategia farmacoinvasiva (p = 0.235). Conclusiones: El antecedente de ICP no incrementa el riesgo de eventos cardiovasculares mayores a los 30 días en pacientes con IAMCEST; sin embargo, impacta negativamente en el flujo sanguíneo angiográfico final de los pacientes que recibieron terapia farmacoinvasiva (en comparación con ICP primaria).
Abstract Background: The prognosis of patients with ST-segment elevation myocardial infarction (STEMI) and previous percutaneous coronary intervention (PCI) is uncertain. Objectives: To evaluate if previous PCI in patients with STEMI increases the risk of major cardiovascular events, and if final epicardial blood flow differs according to the reperfusion strategy. Material and methods: Observational, longitudinal, comparative sub-study of the PHASE-MX trial that included patients with STEMI and reperfusion within 12 hours of symptom onset, who were divided according to their history of PCI. The occurrence of the composite primary endpoint (cardiovascular death, re-infarction, congestive heart failure and cardiogenic shock) within 30 days was evaluated using Kaplan-Meier estimates, log-rank test and Cox proportional hazards model. Final epicardial blood flow was assessed using the TIMI grading system after reperfusion. Results: A total of 935 patients were included; 85.6% were males, and 6.9% had a history of PCI; 53% underwent pharmacoinvasive therapy, and 47%, primary PCI. The incidence of the composite primary endpoint at 30 days in patients with a history of PCI was 9.8% vs. 13.3% in those with no previous PCI (p = 0.06). Among the patients with previous PCI, 87.1% reached a final TIMI grade 3 flow after primary PCI vs. 75% in the group with pharmacoinvasive strategy (p = 0.235). Conclusions: A history of PCI does not increase the risk of major cardiovascular events at 30 days; however, it impacted negatively on the final angiographic blood flow of patients that received pharmacoinvasive therapy (compared to primary PCI).

Objective Coronary arteriography(CAG)and percutaneous coronary intervention(PCI)are the most effective methods for the treatment of coronary atherosclerotic heart disease(CAD),but radial artery vascular variation,especially the presence of 360° tortuous(annular tortuous)radial artery seriously affects the success rate of trans-radial artery approach(TRA)interventional operation.This article provides a preliminary exploration of CAG and PCI through the annular tortuous radial artery.Methods We retrospectively analyzed 15 patients with annular tortuous right radial artery who successfully completed CAG or PCI by annular tortuous radial artery,and summarized the procedures performed through the annular tortuous radial artery.Results We found that the annular tortuous radial artery could be passed through by the catheter with the assistance of percutaneous transluminal coronary angioplasty(PTCA)guide wire or combined with a diameter of 2.0 mm balloon(6-8 atm dilatation state),and then the PTCA wire and the balloon can be replaced with a coronary angiography guide wire after the catheter passed through annular tortuous radial artery,and finally the annular tortuous radial artery could be straightened by fixing the coronary angiography guide wire and rotating and pulling the catheter.Finally,the catheter could be advanced to the coronary orifice and subsequent CAG or PCI could be performed while the annular tortuous radial artery was kept straightening.Both the left and right coronary arteries could perform coronary intervention using this technique,and there were no complications such as forearm hematoma or vascular rupture after this operation.Conclusions It is possible to successfully complete the coronary interventional therapy through annular tortuous radial artery by using the technique with the help of PTCA wire combined with balloon.

Objective To evaluate the effects of antihypertensive drugs on renal function after percutaneous transluminal coronary angioplasty. Methods A retrospective analysis was performed on 193 patients who underwent percutaneous transluminal coronary angioplasty and took antihypertensive drugs regularly. Those patients were admitted to Nanjing Drum Tower Hospital during January 2020 to December 2020. The patients were divided into ACEI/ARB group, β-blockers, calcium channel blockers and hydration control group. All patients received routine hydration during the perioperative period. The changes of serum creatinine (Scr), blood urea nitrogen (BUN), estimated glomerular filtration rate(eGFR) and endogenous creatinine clearance rate (Ccr) before and after operation were compared. Results The incidence of CIN was 0% in four groups. Compared with the preoperative, there was no significant change in Scr and Ccr in every group. Except for the hydration control group, the BUN levels in three treated groups were reduced after postoperative. Specifically, the BUN reduction in β-blockers group has statistically significant difference compared to the hydration control group and CCB group. In addition, eGFR levels were significantly reduced in the β-blockers group. Preoperative Scr and Ccr levels in patients with high blood pressure (SBP≥140 or DBP≥90) were significantly different from the patients with normal blood pressure (SBP<140 and DBP<90). Conclusion The use of ACEI/ARB and CCB before percutaneous transluminal coronary angioplasty had no effect on renal function in the short term. β-blockers can slightly reduce renal function, especially in patients with high blood pressure, who should receive special attention.
摘要
RESUMEN El ejercicio físico evita las enfermedades cardiovasculares pero cuando es intenso debe tener planificación y dosificación correctas y, de ser posible, es muy útil contar con una prueba ergométrica previa y un especialista orientador; porque también puede producir accidentes cardiovasculares en deportistas de alto rendimiento, entre otras cosas, por no cumplir con una programación bien definida con un basamento científico. La complicación más temida es la muerte súbita cardíaca, habitualmente por arritmias malignas y enfermedad isquémica. Se presenta el caso de un deportista de alto rendimiento, de 34 años de edad, en fase desentrenamiento y sin factores de riesgo cardiovascular u otros antecedentes de interés, que sufrió un infarto agudo de miocardio anterior extenso, con angina postinfarto, debido a una estenosis suboclusiva de la descendente anterior proximal. Se realizó angioplastia de rescate, con implantación de un stent farmacoactivo y el paciente evolucionó favorablemente.
ABSTRACT Physical exercise avoids cardiovascular diseases but when it is intense, it must have correct planning and dosage and, if possible, a previous ergometric test and a guidance specialist could be very useful; because it can also cause cardiovascular events in high performance athletes, among other things, for not complying with a well-defined schedule with a scientific base. The most feared complication is sudden cardiac death, usually due to malignant arrhythmias and ischemic heart disease. Here is presented the case of a 34-year-old high-performance athlete, in the detraining phase and without cardiovascular risk factors or other history of interest, who suffered an extensive acute myocardial infarction, with post-infarction angina, due to a stricture suboclusive of the proximal left anterior descending artery. A rescue angioplasty was performed, with implantation of a drug-eluting stent and the patient evolved favorably.

Resumen Introducción La oclusión coronaria aguda, asociada a alta tasa de morbimortalidad en el infarto agudo del miocardio con elevación del segmento ST (IAMCEST), representa un desafío para el intervencionista cuando desconoce el importe de carga de trombo y las características distales a la oclusión (obstrucción microvascular (OMV), estenosis distal) que complican la angioplastia primaria (ACTP) y el fenómeno de no reflujo (FNR), el cual tiene una incidencia reportada de 20 a 40%. Objetivos Evaluar la eficacia de la angiografía distal con microcatéter al orientar una estrategia terapéutica individualizada con la finalidad de prevenir el FNR en oclusión coronaria aguda por IAMCEST en ACTP. Material y métodos Se incluyeron 70 pacientes con IAMCEST. Se realizó angiografía con microcatéter distal a la obstrucción y se eligió la estrategia terapéutica en la angioplastia de conformidad con hallazgos: estenosis, carga de trombo y OMV. Posteriormente se evaluó la incidencia de FNR al finalizar la ACTP. Resultados Reporte de 70 pacientes, la mayoría hombres (80%), clase Killip-Kimball I (95%), con afección de la arteria coronaria derecha en 57% de ellos y de la descendente anterior en 37%. Trombo distal presente en 47% de los pacientes estudiados, se observó en 21% de los casos que la longitud de obstrucción fue mayor de 30 mm, disección de las arterias también en 21%, OMV presente en 41% y 25% con estenosis distal. Estrategias terapéuticas utilizadas: se aplicó stent con fármaco en 81% de los pacientes, balón largo en 93% y trombolítico en 30%. Se observó una incidencia del FNR de 18.6%. Conclusiones En IAMCEST la técnica propuesta disminuye el FNR en comparación con lo reportado. La obstrucción > 30 mm es factor independiente de FNR, por lo que en estos casos recomendamos el uso de esta técnica y balón largo.
Abstract Introduction The acute coronary occlusion associated with a high valuation of morbimortalidad in the acute infarction of the myocardium with elevation of the ST segment (STEMI), represents a challenge for the interventionist, due the unknown amount of thrombus load and its characteristics beyond the occlusion (microvascular obstruction (MVO), distal stenosis), which leads to complicate the primary angioplasty (PTCA) and to the no reflow phenomenon (NFP), which has an overall incidence reported from 20 to 40%. Objectives To evaluate the efficacy of the distal coronary angiography with microcatheter, that leads to an individualized therapeutic strategy, with the purpose of prevent the NFP in the accute coronary occlusion in STEMI treated with PTCA. Material and methods 70 patients were included with STEMI. We performed coronary angiography with microcatheter distal to the obstruction, and the therapeutic strategy was chosen in accordance with findings: stenosis, thrombus amount or MVO. After the PTCA were performed, we evaluated the NFP incidence. Results Report of 70 patients, the majority men (80%), class Killip Kimbal I (95 %), with disease of the right coronary artery in 57%, and anterior descending coronary artery in 37%. Distal thrombus was present in 47% of the studied patients. An obstruction length of more than 30 mm was observed in 21% of the cases, also we observed dissection of the arteries in a 21%, MVO was presented in 41%, and distal stenosis in 25%. Used therapeutic strategies: It was applied medicated stent in 81% of the patients, long balloon in 93%, and thrombolytic therapy in 30%. We observed a NFP incidence of 18.6 %. Conclusions The diagnostic and therapeutic approach for STEMI that this study recommends, diminishes the NFP in comparison with reported. An obstruction > 30 mm is an independent factor for NFP, therefore in these cases we recommend use the described diagnostic approach and long balloon.
摘要
Drug-coated balloons (DCB) have emerged as a new application in percutaneous coronary intervention. It is developed to circumvent some of the limitations faced by drug-eluting stents (DES). DES has some limitations, as follows: it could not be implanted in some lesions; bleeding risks are associated with prolonged dual antiplatelet therapy; risks of late and very late stent thrombosis increase. Many clinical trials had confirmed the efficacy and safety of DCB, particularly, the application of DCB in coronary small vessel diseases. This review discussed the basic concept, development, evolution of DCB and some clinical studies associated with the application of DCB in coronary small vessel diseases.

Objective To compare the prognosis of vascular in situ and bridge vessel percutaneous coronary intervention ( PCI) therapy strategies in patients with recurrent angina after coronary artery bypass grafting ( CABG) . Methods A total of one hundred and two patients with recurrent angina after CABG from January 2008 to January 2016 were involved in this study and were divided into two groups according to interventional therapy strategy:74 patients in the vascular in situ PCI group ( in situ group,74 cases) and 28 patients for bridge vessel PCI group ( bridge vessel group,28 cases) . The patients have been followed up for (33. 6± 10. 2) months. The major adverse cardiovascular events ( MACE) of the two groups were recorded, including non?fatal acute myocardial infarction ( AMI) ,target vessel revascularization ( TVR) and cardiac death, and multivariate logistic regression analysis was used to analyze the related factors of MACE. Results Compared with the bridge vessel group,the non?MACE survival rate,non?AMI survival rate and non?TVR survival rate of the in situ group were significantly increased ( ( 71. 6% ( 53/74 ) vs. 57. 1% ( 16/28 ) , 93. 2% ( 69/74 ) vs. 82. 1% (23/28),81. 1% (60/74) vs. 67. 9% (19/28) ),the differences were statistically significant (χ2=8. 141,4. 219,5. 436, P<0. 05) . Multivariable logistic regression analysis showed that age of bridge ( OR=1. 023,95%CI 1. 005-1. 026,P=0. 019) ,diabetes mellitus ( OR=2. 386,95%CI 1. 425-3. 991,P=0. 003) and bridge vessel PCI (OR=1. 884,95%CI 1. 093-3. 220,P=0. 025) were factors that affect the clinical prognosis in patients with recurrent angina pectoris after CABG. Conclusion The clinical prognosis of the in situ PCI is better than bridge vascular PCI in patients with recurrent angina after CABG,while the age of bridge, diabetes mellitus, vascular interventional treatment are factors for the effect of interventional therapy patients prognosis. The clinical prognosis is much better in native vessel PCI than that of bridge vessel PCI in patients with recurrent angina after CABG. The age of bridge,diabetes mellitus and bridge vessel PCI are the factors that affect the clinical prognosis in the patients.

Fundamentos: A intervenção coronariana percutânea(ICP) promove melhora sintomática e menor necessidade de antianginosos na doença coronariana estável, masnão reduz a incidência de infarto do miocárdio e morte. Objetivo: Avaliar a adequação das indicações de ICPem pacientes com doença coronariana estável em um hospital universitário.Métodos: Foram estudados 102 pacientes com doença coronariana estável submetidos consecutivamentea ICP em um hospital universitário, com média de idade de 65,9±10,7 anos, sendo 67,3 % homens. Coletaram-se informações referentes ao paciente(dados clínico-epidemiológicos, resultados de testes provocativos de isquemia e uso de antianginosos) e aomédico solicitante (tempo de formação e especialidade). Considerou-se adequada a indicação de ICP a pacientes com angina do peito refratária ao tratamento clínico ou a pacientes assintomáticos apresentando grande área de isquemia miocárdica em testes provocativos.Resultados: A indicação de ICP foi considerada adequada em 34 (33,3 %) pacientes, inadequada em 2 e incerta nos 66 restantes. À análise univariada,mostraram-se significativamente associadas à indicação de ICP inadequada/incerta as variáveis: idade mais elevada (p=0,001), aposentadoria (p=0,006) e ausência de tabagismo (p=0,041) e de dislipidemia(p=0,039), observando-se tendência à significância em relação a sedentarismo (p=0,094), renda mais baixa(p=0,013) e tempo de formação do médico solicitante ≥10 anos (p=0,094). Após análise de regressão logística,apenas idade mais elevada (OR=1,10 [1,06-11,1]; p=0,048), renda mais baixa (OR=2,84 [1,5-7,6]; p=0,039)e maior tempo de formação do médico solicitante...
Background: Percutaneous coronary intervention (PCI) results in improved symptoms and less need forantianginal medications for stable coronary artery disease, but does not reduce myocardial infarction and death rates. Objective: To assess the appropriateness of PCIindications in patients with stable coronary artery disease at a university hospital. Methods: The study involved 102 patients with stable coronary artery disease consecutively undergoing PCIat a university hospital, with a mean age of 65.9 ± 10.7 years and 67.3% male. Information was collected on the patient (clinical and epidemiological data,ischemia provocation test results and antianginal drug use) and the requesting physician (time since graduation and speciality). PCI indications wereconsidered appropriate for patients with angina pectoris to clinical treatment, or for asymptomatic patients presenting large areas of myocardial ischemia in provocation tests. Results: PCI indications were consideredappropriate for 34 (33.3%) patients, inappropriate for two others, and uncertain for the remaining 66.In the univariate analysis, the following variables were significantly associated with inappropriate/uncertain ICP indications: older (p=0.001), retired(p=0.006), non-smoker (p=0.041) and dyslipidemia (p=0.039), noting a trend towards sedentary lifestyles (p=0.094), lower income (p=0.013) and≥10 years time since graduation (p=0.094). After the logistic regression analysis, only the older (OR=1.10 [1.06-11.1]; p=0.048), lower income(OR=2.84[1.5-7.6]; p=0.039) and longer time since...

Although atrial fibrillation is the most frequent cause of embolic stroke, coronary embolism from atrial fibrillation is a very rare cause of acute myocardial infarction. Therefore, simultaneously presented acute ischemic stroke and acute myocardial infarction due to atrial fibrillation in the same patient has not been documented. The present report describes the case of a 58-year-old man with paroxysmal atrial fibrillation who initially presented with a large cerebral infarction due to embolic occlusion of the left middle cerebral artery. Four hours after the diagnosis of cerebral embolism, he was subsequently diagnosed with acute myocardial infarction due to concurrent coronary embolism. He underwent successful coronary revascularization with a drug-eluting stent. The possibility of combined coronary embolism as a rare etiology should be kept in mind when a patient with acute embolic stroke presents, especially when there is evidence of acute myocardial infarction.

摘要
PURPOSE: Thiazolidinediones are insulin-sensitizing agents that reduce neointimal proliferation and the adverse clinical outcomes associated with percutaneous coronary intervention (PCI) in patients with diabetes mellitus (DM). There is little data on whether or not low dose pioglitazone reduces adverse clinical outcomes. MATERIALS AND METHODS: The study population included 121 DM patients with coronary artery disease and they were randomly assigned to 60 patients taking 15 mg of pioglitazone daily in addition to their diabetic medications and 61 patients with placebo after the index procedure with drug-eluting stents (DESs). The primary end points were rate of in-stent restenosis (ISR) and change in atheroma volume and in-stent neointimal volume. The secondary end points were all-cause death, myocardial infarction (MI), stent thrombosis and re-PCI. RESULTS: There were no statistical differences in the clinical outcomes and the rate of ISR between the two groups [all-cause death; n=0 (0%) in the pioglitazone group vs. n=1 (1.6%) in the control group, p=0.504, MI; n=2 (3.3%) vs. n=1 (1.6%), p=0.465, re-PCI; n=6 (10.0%) vs. n=6 (9.8%), p=0.652, ISR; n=4 (9.3%) vs. n=4 (7.5%), p=1.000, respectively]. There were no differences in changes in neointimal volume, percent neointimal volume, total plaque volume and percent plaque volume between the two groups on intravascular ultrasonography (IVUS) study. CONCLUSION: Our study demonstrated that low dose pioglitazone does not reduce rate of ISR, neointimal volume nor atheroma volume in DM patients who have undergone PCI with DESs, despite the limitations of the study.

Despite an increasing prevalence and burden of disease in the elderly, little is known about the management and outcomes of acute coronary syndromes in this group. We report the case of a 101-year-old female patient with a non-ST segment elevation myocardial infarction. Coronary angiography showed a total occlusion of the proximal right coronary artery (RCA), and a significant stenosis in the proximal to mid left anterior descending artery (LAD). Despite a very poor initial clinical status, a percutaneous coronary intervention was successfully performed for the total occlusion in the RCA. The LAD lesion was treated with medical therapy only, on account of the age and general condition of the patient. She was discharged after recovering to a good health status, free of chest pain or dyspnea.

Most type I and II perforations are predominately caused by hydrophilic and stiff wires, often presented in the delayed form, and do not require pericardial drainage or surgical interventions. However, we report a type III delayed coronary artery perforation at the site of stent implantation after intervention without any evidence of immediate perforations. To the best of our knowledge, this is the first case report of angiographic documentation and treatment of delayed coronary perforation at the site of stent, presented as a cardiac arrest.

PURPOSE: The optimum loading dose of clopidogrel has not been established in Asian patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Our aim was to evaluate the impact of different clopidogrel loading doses on short- and long-term clinical outcomes in Asian STEMI patients undergoing primary PCI. MATERIALS AND METHODS: We studied 691 STEMI patients undergoing primary PCI, loaded with 600 mg (n=381) or 300 mg (n=310) of clopidogrel. The primary outcome was major adverse cardiac events (MACEs), defined as a composite of all-cause death, reinfarction, or target vessel revascularization (TVR). RESULTS: Baseline clinical and peri-procedural characteristics were mostly comparable between the 600 mg and 300 mg groups. There were no differences in 1 month MACEs as well as all-cause death, reinfarction, TVR, and stent thrombosis between the two groups. After a median follow-up of 921 days, MACEs [adjusted hazard ratio (HR) for the 600 mg group 1.79, 95% confidence interval (CI): 0.80-3.97, p=0.153], all-cause death (adjusted HR for the 600 mg group 0.97, 95% CI: 0.50-1.88, p=0.928), reinfarction (adjusted HR for the 600 mg group 1.03, 95% CI: 0.55-1.91, p=0.937), and TVR (adjusted HR for the 600 mg group 1.36, 95% CI: 0.68-2.69, p=0.388) did not differ between the two groups. These results were reliable even after analysis of propensity score-matched population, and were also constant among various subgroups. CONCLUSION: A 600 mg loading dose of clopidogrel did not result in better short- and long-term clinical outcomes in Asian STEMI patients undergoing primary PCI.

Fluoroscopy-induced chronic radiation dermatitis (FICRD) is a cutaneous disorder that results from prolonged exposure to ionizing radiation during interventional procedures. With the expanded use of interventional procedures, there is increased fluoroscopic exposure. However, diagnosis and treatment of such disorder remain difficult. Herein, we report on a case of FICRD that occurred in the right subscapular area.
