Rice Bran’s Effect on Total Cholesterol, HDL, and LDL/HDL Ratio on Hypercholesterolemia Rats

Abstract: Hypercholesterolemia is a metabolism disorder characterized by increased or decreased lipid fraction in plasma. The of this research was to prove the effect of Rice bran to decrease of total Cholesterol rate, ratio of LDL / HDL and increase rate of HDL in hypercholesterolemia male white rats (Rattus norvegicus). The Research of the study was pure experiment by using post test randomized control design. Research Sample divided into five groups. The first group as a negative control, the second group as a positive control, and another groups were given rice brand, with various dose: 0,54 ml/a/day, 1,08 ml/a/day, 1,62 ml/a/day. The results of this research is rice brand can decrease of total cholesterol rate ( r2=0,964), decreased of ratio of LDL / HDL (r2=0,836), and increase of rate of HDL (r2=0,951) (ANOVA P=0,000). Rice bran can decrease total cholesterol rate, ratio of LDL / HDL and increase rate of HDL blood.

Highlighting the role of global longitudinal strain assessment in valvular heart disease

Background

Echocardiography has been the choice for imaging modality for valvular heart disease. It is less invasive, widely available, and allows valvular structure visualization. Echocardiographic assessment often also determines the management. Left ventricular ejection fraction is the most commonly used indicator during echocardiography assessment. It shows signs of left ventricular dysfunction in patients with valve disease. However, most of the time, the ongoing process of cardiac damage may already occur even with preserved cardiac function; further deteriorated ejection fraction will show irreversible cardiac damage. There is a need for a more advanced diagnostic tool to detect early cardiac dysfunction, to prevent further damage.

Main body

Advanced echocardiography imaging using strain imaging allows a physician to evaluate cardiac function more precisely. A more sensitive parameter than left ventricular ejection fraction, global longitudinal strain, can evaluate subclinical myocardial dysfunction before the symptoms occur by evaluating complex cardiac mechanisms. Global longitudinal strain evaluation provides the chance for physicians to determine the intervention needed to prevent further deterioration and permanent cardiac dysfunction. Global longitudinal strain is proven to be beneficial in many types of valvular heart diseases, especially in mitral and aortic valve diseases. It has an excellent diagnostic and prognostic value for patients with valve disease. This review aims to present the superiority of global longitudinal strain compared to left ventricular ejection fraction in assessing cardiac function in patients with valvular heart disease. Clinical usage of global longitudinal strain in several valvular heart diseases is also presented in this review.

Conclusions

The superiority of global longitudinal strain to left ventricular ejection fraction relies on the mechanism where other strains would compensate for the deterioration of longitudinal strain, which is more vulnerable to damage, so the cardiac function is preserved. Therefore, examination of longitudinal strain would give the physician early signs of cardiac function impairment, and prompt management can be conducted.

Arrhythmia-induced Cardiomyopathy: An Article Review

Arrhythmia is one of the significant reversible causes in patients with heart disease and left ventricular dysfunction. Tachycardia, atrial fibrillation, and premature ventricular contractions have indeed been related to arrhythmia-induced cardiomyopathy (CM), a reversible dilated CM. Effective arrhythmia suppression will entirely or partially recover ventricular function, lowering morbidity and mortality. However, the importance of arrhythmia-induced CM (ARiCM) is often underestimated in clinical practice because arrhythmia is often seen as a result rather than a cause of CM, leading in treatment delays and failure to increase the quality of life and better clinical outcomes. This article review aims to summarize the pathomechanisms, and a general approach to the management of ARiCM and its long-term outcomes. ARiCM can cause a variety of clinical signs, ranging from asymptomatic to severe heart failure symptoms. Electrocardiogram, 24 h Holter monitoring, echocardiography, and cardiac magnetic resonance are all recommended for diagnosis. More research is required to better understand the pathogenesis of ARiCM and to differentiate treatment alternatives to choose the ideal ARiCM management approach.

Atrial Failure: What Do We Know About It?

Heart failure is the end of all pathological conditions in the heart. Most accepted paradigms in heart failure are always preceded by left ventricle disfunction. Currently, there are several clinical studies that show that heart failure may occur without prior left ventricular dysfunction. Left atrial dysfunction may play a more important role in heart failure than previously expected. Failure of the left atrium can exist independently of left ventricle dysfunction and mitral valve abnormalities. Atrial failure, just like left ventricular failure, can lead to global heart failure. Etiology, pathomechanism and clinical symptoms of atrial failure are complex and not well understood. This review will explain atrial failure.

A Case of Malignant Right Coronary Artery: Frequent Angina in Young Person

Highlight:A young adult has activity-triggered atypical chest pain and diagnosed malignant RCA.Congenital anomalies  needed to be aware by cardiologists to help clinical practice.Planning a treatment about management of the CAAs condition should be undertaken by the inter-specialist team. Abstract:We presented a case a young adult with activity-triggered atypical chest pain and diagnosed with anomalous origin of right coronary artery (RCA) from the left coronary sinus with an interarterial course between the aorta and the main pulmonary artery that was detected by CT coronary angiography. This anomaly has been called malignant RCA. Coronary artery anomaly is a congenital condition. Most of the cases remain asymptomatic. This condition is also one of the most causes of sudden cardiac death, because the coronary artery examination is not regularly done. Nevertheless, during high intensity activity, it could be symptomatic and might be lethal. Diagnosing coronary artery anomalies might be tricky and cardiologists must be aware of this. The CAAs condition is a rare situation. The CAAs condition is associated with sudden death, especially intense physical activity. There was no rigid guideline for the management of the CAAs condition, so that planning a treatment in the inter-specialist team should be done.

Metabolic syndrome and heart failure: mechanism and management

Heart failure (HF) and metabolic syndrome (MetS) are syndromes that affect a large proportion of the world population. MetS is known to be one of the risk factors of HF, and it can also act as comorbidity in HF. This review aims to further discuss the mechanism of MetS in causing HF, the management of MetS in order to prevent HF, and the management of MetS in HF patients. Visceral adiposity is the primary trigger of MetS which is followed by chronic inflammation, insulin resistance, and neurohormonal activation. All the mechanisms causing MetS play also an important role in the progression of HF. The MetS approach can be achieved by managing its components according to the current guidelines and careful management of MetS should be done in patients with HF. MetS is closely related to the progression of HF so that comprehensive management which involves a multidisciplinary team is necessary for managing patients with metabolic syndrome and heart failure.

Endovascular Surgery or Both: A Case Report of Hybrid Procedure in a Patient with Abdominal Aortic Aneurysm and Tasc D Aortoiliac Occlusive Disease

Hybrid procedure, a combination of endovascular and open surgical approach, has emerged as the first-line treatment for patients with severe aortoiliac diseases because of its effectiveness. We report a hybrid procedure in a 72 year old man with an Abdominal Aortic Aneurysm (AAA) and Trans-Atlantic Inter-Society Consensus (TASC) D aortoiliac occlusive disease. After two failed attempts using the intraluminal technique (retrograde and antegrade), we successfully performed an endovascular approach with subintimal and Subintimal Arterial Flossing Antegrade-retrograde Intervention (SAFARI) technique with the help of roadmap technology. The vascular surgeon completed the procedure by creating femorofemoral bypass using a Great Saphenous Vein (GSV) graft. The graft was patent and there were no complications at 1 week, 1 month and 6 months follow-up.

Exercise Training Improved Longitudinal Intrinsic Left Ventricle Function in Heart Failure with Preserved Ejection Fraction

Exercise improves morbidity, fatality rate, and quality of life in heart failure with low ejection fraction, but fewer data available in heart failure with preserved ejection fraction (HFPEF). The purpose of this study is to test the hypothesis that exercise training might improve the longitudinal intrinsic left ventricular (LV) function in HFPEF patients. This quasi-experimental study had recruited 30 patients with HFPEF. Exercise training program had been performed for a month with a total of 20 times exercise sessions and evaluated every 2 weeks. Echocardiography was performed before sessions, second week and fourth week of exercise training. Six-minute walk tests (6MWTs) and quality-of-life variables using Minnesota living with HF scoring and the 5-item World Health Organization Well-Being Index scoring were measured before and after exercise as well. Left ventricular filling pressure, represented by the ratio of early diastolic mitral flow velocity/early diastolic annular velocity and left atrial volume index, improved during exercise. The longitudinal intrinsic LV function, represented by four-chamber longitudinal strain, augmented during exercise ( p  < 0.001). Aerobic capacity, measured by 6MWT, increased significantly ( p  = 0.001). Quality of life improved significantly during exercise ( p  < 0.001). Exercise training was suggested to improve the longitudinal intrinsic LV function and quality of life in HFPEF. Clinical Trial Registration: ACTRN12614001042639.
