Acute coronary syndrome due to native coronary occlusion proximal to a patent bypass graft: a case report.

BACKGROUND: Primary percutaneous coronary intervention (PCI) for acute coronary syndrome has significantly contributed to improvements in overall outcomes. However, clinical challenges exist when performing urgent PCI for patients with a history of coronary artery bypass grafting (CABG). CASE SUMMARY: An 83-year-old man with a history of CABG presented with an inferior ST-elevation myocardial infarction (STEMI). Emergent coronary angiography showed an occlusion of the right coronary artery that had been previously grafted with the right gastroepiploic artery. Primary PCI for the native coronary artery was performed on the assumption that the bypass graft had been occluded. We were unable to attain angiographic antegrade flow after balloon angioplasty, and intravascular ultrasound revealed a ruptured plaque with a thrombus proximally and a patent bypass graft with complete recanalization distally. These findings suggested that the plaque rupture with resultant thrombus formation proximal to the anastomosis eventually overlay the patent bypass graft. Subsequent stent implantation covering only the culprit site with a residual stenosis proximal to the anastomosis was performed, resulting in good patency of both the native coronary artery and bypass graft for more than 3 years. DISCUSSION: This is the first documented case of a patient with STEMI due to proximal native coronary artery occlusion with a thrombus overlying a patent bypass graft. Intravascular ultrasound was helpful to recognize the distal patency and guide optimal stent implantation. This case illustrates the complexity of treating a patient with a history of CABG and the importance of a multifaceted approach in such an urgent situation.

Management instructions for elderly patients with hypertension.

Aim: To compare the understanding of hypertension and antihypertensive treatment in Japanese patients (aged <75 years vs. ≥75 years) with blood pressure (BP) targets as per the 2014 Japanese guidelines.Methods: A 10-question survey was administered before and after treatment.Results: Majority of patients aged ≥75 years did not achieve their BP targets (75%); >50% of these patients had little knowledge of hypertension and poor understanding of their physician's explanation of it.Conclusions: Elderly patients with hypertension (aged ≥75 years) require daily BP monitoring and detailed and repeated explanation of hypertension and BP targets.

Questionnaire Survey From the Viewpoint of Concordance in Patient and Physician Satisfaction Concerning Hypertensive Treatment in Elderly Patients　- Patients Voice Study.

BACKGROUND: Patient-physician concordance is an important concern in the treatment of elderly patients with hypertension (HT). Treatment that considers concordance is necessary for mutual understanding and therapeutic satisfaction between patients and physicians. However, there have been no studies addressing concordance that objectively analyzed both patient and physician satisfaction before and after treatment.Methods and Results:An exploratory open-label, multicenter, intervention study was conducted. Patients with HT undergoing treatment with angiotensin-receptor blocker (ARB) or a calcium-channel blocker (CCB) monotherapy were enrolled. Medication was switched to an ARB/CCB combination tablet and taken for 12 weeks. Physicians and patients participated in satisfaction surveys concerning treatment. Discrepancies in satisfaction levels between patients and physicians were found at baseline for the following survey items: treatment, involvement in treatment, understanding of HT, reliance, medication, and blood pressure. After treatment, the satisfaction levels of both patients and physicians increased; discrepancies in satisfaction between the groups also improved. CONCLUSIONS: The rates of satisfaction were relatively higher for patients compared with physicians at baseline. After HT treatment addressing concordance, both patient and physician satisfaction rates and the gap in satisfaction rates between patients and physicians improved. This indicates that addressing concordance has clinical significance in the treatment of elderly HT patients. (UMIN000017270).

[Malignant lymphoma with various cardiac manifestations: a case report].

A 49-year-old woman presented with malignant lymphoma manifesting as dyspnea, palpitation and leg edema. Chest radiography demonstrated cardiomegaly, electrocardiography(ECG) showed first degree atrioventricular block, and echocardiography showed concentric left ventricular hypertrophy with granular sparkling texture and mild pericardial effusion. The diagnosis was malignant lymphoma(B-cell) based on lymph node biopsy. Chemotherapy(CHOP) was performed under a suspected diagnosis of cardiac invasion of malignant lymphoma. Immediately after chemotherapy, ECG showed complete atrioventricular block with sinus arrest, ventricular fibrillation and atrial fibrillation. ECG was normalized after 2 weeks on chemotherapy. Left ventricular hypertrophy was improved and pericardial effusion disappeared. However, she died of recurrence of malignant lymphoma on day 116.
