The Face Is the Mirror of the Soul. The Cardiovascular Physical Exam Is Not Yet Dead!

Cardiac pathology can be congenital or acquired with underlying genetic predispositions. In this era of medicine there is a concern that the comprehensive physical examination doctors prided themselves on is becoming a lost art. Research studies have also revealed a decline in physical examination skills. The full clinical cardiovascular examination is indeed quite complex and does take significant time to master. It is critical that physicians be competent in the physical exam. Not identifying subtle clinical findings leading to missed or delayed diagnosis which can lead to significant morbidity and mortality. In this paper we intend to highlight the clinical cardiovascular findings that may be detected on patients even before initiating the physical exam. The head and neck visual examination may be quite revealing.

When the gold standard is not always golden: The value of invasive hemodynamic assessment to overcome the pitfalls of echocardiography in challenging cases of mitral stenosis.

Mitral stenosis is a uncommon valvular lesion in the developed countries. Noninvasive evaluation is the first-line modality for assessment of mitral stenosis, however the noninvasive methods may have limitations in certain cases. Invasive hemodynamics can be used as adjunct tool for assessment of mitral stenosis in such difficult cases. Mitral valve using three-dimensional planimetry is a promising technique for assessment of mitral stenosis.

Peripheral interventions and antiplatelet therapy: Role in current practice.

Peripheral arterial disease (PAD) is a common disorder associated with a high risk of cardiovascular mortality and continues to be under-recognized. The major risk factors for PAD are similar to those for coronary and cerebrovascular disease. Management includes exercise program, pharmacologic therapy and revascularization including endovascular and surgical approach. The optimal revascularization strategy, endovascular or surgical intervention, is often debated due to the paucity of head to head randomized controlled studies. Despite significant advances in endovascular interventions resulting in increased utilization over surgical bypass, significant challenges still remain. Platelet activation and aggregation after percutaneous transluminal angioplasty of atherosclerotic arteries are important risk factors for re-occlusion/restenosis and life-threatening thrombosis following endovascular procedures. Antiplatelet agents are commonly prescribed to reduce the risk of myocardial infarction, stroke and death from cardiovascular causes in patients with PAD. Despite an abundance of data demonstrating efficacy of antiplatelet therapy in coronary artery disease and cerebrovascular disease, there is a paucity of clinical information, clinical guidelines and randomized controlled studies in the PAD population. Hence, data on antiplatelet therapy in coronary interventions is frequently extrapolated to peripheral interventions. The aim of this review article is to elucidate the current data on revascularization and the role and duration of antiplatelet and anticoagulant therapy in re-vascularized lower limb PAD patients.

Protease-Activated Receptor 1 Inhibitors: Novel Antiplatelet Drugs in Prevention of Atherothrombosis.

Protease-activated receptor (PAR)-1 inhibitors have recently become popular in the use of atherosclerosis among clinicians. Atherosclerosis can cause cardiovascular and cerebrovascular events leading to one of the major causes of mortality worldwide. Thrombin-mediated platelets can cause atherosclerotic plaques, and these platelets are activated by thrombin through the PAR-1. Vorapaxar and atopaxar are novel antiplatelet drugs that inhibit the thrombin-induced platelet activation by antagonizing the PAR-1. The objective of this article is to review the mechanism of action of vorapaxar and atopaxar and explain the rationale for using them in atherothrombosis patients including myocardial infarction, peripheral arterial disease, and stroke.

When life-threatening conditions appear clinically silent: an atypical presentation of spontaneous coronary artery dissection in a 60-year-old female.

Spontaneous coronary artery dissection is a poorly understood phenomenon that usually affects women during pregnancy or the immediate post-partum period. We present the case of a 60-year-old female with chronic obstructive pulmonary disease who presented with vague complaints of shortness of breath, dizziness, and weakness with a mildly elevated troponin. She denied any anginal symptoms. As part of her initial workup, a nuclear stress test revealed inferior wall reversible changes. Coronary angiography revealed spontaneous right coronary artery dissection which was treated with a drug-eluting stent.
