  1. Fulltext Cardiac mass in a patient with sigmoid adenocarcinoma: a metastasis?
    Ngow HA, Khairina WM
    Cardiovasc J Afr, 2012 Aug;23(7):e10-2.

    Cardiac metastasis from a bowel malignancy seldom occurs and there is a limited number of case reports published on this subject. Although colorectal cancer is the third commonest malignancy in Malaysia, the incidence of cardiac metastasis has never been reported. We report a case of an elderly man with recently diagnosed adenocarcinoma of the sigmoid colon, who presented with congestive cardiac failure secondary to mechanical obstruction by a right atrial mass. The intractable shock led to his sudden death before any intervention could be planned. If an intra-cavity cardiac mass is detected in a patient with an underlying metastatic malignancy, cardiac metastasis should be suspected. However, primary cardiac tumour or thrombus could also be the differential diagnosis. In our case, the definitive cardiac pathology remained unsolved as an autopsy was refused.
  2. Fulltext Influence of visceral fat and blood pressure on changes in blood flow velocity in non-obese individuals

    Cardiovasc J Afr, 2018;29(3):146-149.

    INTRODUCTION: The aim of this study was to evaluate the impact of different visceral fat (VF) and blood pressure (BP) levels on changes in blood flow velocity (BFV) among non-obese subjects, using a cross-sectional study approach.

    METHODS: A total of 110 putatively healthy and non-obese subjects were divided into three groups according to their level of VF and BP. Common carotid artery BFV was measured using a developed portable Doppler ultrasound measurement system.

    RESULTS: The most pronounced peak systolic velocity (S1) was lower (p < 0.05) in the hypertensive group and the peak diastolic velocity (D) was significantly lower in the pre-hypertensive group than in the normotensive group. There were differences in velocity reflection and resistive indices between the hypertensive and other two BP groups. The higher VF group had significantly lower S1 and D velocities and resistive and vascular elasticity indices. By contrast, the velocity reflection index was larger in the higher VF group.

    CONCLUSIONS: We confirmed that there were significant differences in the BFV among non-obese subjects who differed in level of VF and BP. This study confirms that a putatively increasing VF and BP level is associated with the development of hypertension.
